Os motores de indução monofásicos necessitam de dois enrolamentos estatóricos para criação de um campo magnético girante: um enrolamento principal e um enrolamento auxiliar. Este último tem o objetivo de criar um campo girante apenas na partida do motor, desligando-se logo em seguida, através de um interruptor centrífugo acoplado ao eixo do rotor da máquina. O objetivo deste trabalho é avaliar a influência das diferentes configurações de enrolamentos sobre as características externas do motor de indução monofásico. Sendo assim, através desta análise, pretende-se verificar se há algum benefício em seu desempenho. Neste trabalho, duas configurações de enrolamentos foram desenvolvidas e testadas em laboratório. Na primeira configuração, o enrolamento principal foi alocado na parte inferior das ranhuras. Na segunda configuração, as posições dos enrolamentos foram invertidas. As duas configurações de enrolamento foram aplicadas a um protótipo de 0,37 kW, quatro pólos. A simulação foi realizada através de um programa computacional de elementos finitos, possibilitando a extração e análise de resultados, com as densidades de fluxo nas duas configurações. Os resultados dos ensaios realizados no protótipo permitiram analisar o comportamento de grandezas como corrente elétrica, torque, potência e rendimento que são apresentados e comparados no final deste trabalho.

The single phase induction motor needs two stator windings to produce the rotating magnetic field: a main winding and an auxiliary winding. The aim of the auxiliary winding is to create the rotating electromagnetic field when the machine is starting and afterwards turned off, generally through a centrifugal switch coupled to the shaft of the machine. The main purpose of this work is to evaluate the influence that the position of the two windings have on the external characteristics of the single phase induction motor. For this purpose, two different kinds of winding configurations were carried out and simulated in a prototype. In the first configuration, the main winding was located in the bottom of the slot. In the second configuration, the positions of the windings were inverted. Performance analysis and computational simulation by Finite Element Method were carried out after the prototype 0.37 kW, four poles was prepared. In this way, through this analysis, improvements on its performance are expected. The electrical quantities such as flux density, electric current, torque, power and efficiency are compared in the end of this document.

▼ Voltage fluctuations in distribution networks are a power quality disturbance that can produce a number of undesirable effects, particularly if the level of fluctuation becomes excessive. Utilities and customers have a responsibility of ensuring that levels remain below values that are regarded as acceptable. In order to determine what an acceptable level might be, measurement techniques have been devised that are able to establish a quantitative measure for voltage fluctuations. The basis of these methods is the effect that voltage fluctuations have on the luminous output of the incandescent lamp. This phenomena is referred to as lamp flicker, or simply flicker. The IEC Technical Reports IEC/TR 61000-2-2 and 61000-2-12 define flicker levels that arise in response to voltage fluctuations by using short term and long term flicker severity indices, P_st and <em>P_lt</em>, on the basis of human visual sensation which is generated by the traditional incandescent lamp types. The output from new lamp types such as compact flourescent lights are less sensitive to voltage fluctuations as their flicker characteristics are considerably different compared to those of the traditional incandescent lamp. These differences could support the moderation of the present voltage fluctuation and flicker standards and hence the associated limits. However, the severity indices used to quantify flicker do not account for effects that may be observed in the terminal characteristics of electrical equipment connected to the public supply network. Therefore, the potential detrimental effects on electrical equipment which may be caused by relaxation of these flicker limits should be investigated before any changes to the present standards take place. The related investigation presented in this thesis is motivated by this issue in addition to developing a greater insight into the impact of voltage fluctuations on common items of electrical equipment. The impact of voltage fluctuations on a single-phase, full-bridge rectifier with a capacitor filteris investigated. Such a circuit is found in many different types of equipment. By comparing the DC-link capacitor ripple current characteristic between non-fluctuating and regular fluctuating AC power supplies using mathematical analyses, simulation, and experimental verification, the investigation reveals that the DC-link capacitor will accumulate and dissipate increased amounts of charge when the rectifier is subjected to AC source voltage fluctuations. The consequence of this phenomena is that the RMS value of the capacitor current will increase and the magnitude of this increase is related to the modulation frequency and magnitude of the fluctuating voltage. Therefore, an AC supply with a voltage fluctuation component will cause the capacitor filter of the rectifier circuit to sustain increased stress. This stress may accelerate the capacitor ageing process, possibly resulting in premature equipment failure. Using a simple thermal…

▼ Transformers form a very important part of the power transmissions and distribution network; as they are responsible for the transfer of electrical energy from the power generation sites onto the transmission lines and finally to the distribution stage. Dry-type and oil-filled single-phase transformers, either alone or as a part of three-phase banks, are used extensively in the power distribution network, ultimately providing power to the domestic consumers. Any faults in the single-phase transformers leading to power outages or catastrophic power systems failures cause huge loss of capital, property and in some cases even human casualties. Gradual deterioration of the electrical winding insulation ultimately leads to inter-turn winding short circuit faults; which account for a significant proportion of all transformer failures. Incipient stages of inter-turn winding faults have negligible impact on the terminal voltages and currents of transformers; thus these faults often go undetected by the traditional differential relay based protection mechanisms. By the time, the faults manifest themselves into severe winding short-circuit faults consequently forcing the differential relays to operate for tripping the circuit breakers; a significant part of the transformer windings and core may get extensively damaged. Over the years, various techniques have been developed for detecting and studying inter-turn winding faults; however their practical implementation involves quite a few challenges such as high cost, lack of reliability, low accuracy and need for mounting additional equipment inside the transformer casing. Additionally, none of the existing techniques are suitable for online and real-time condition monitoring of the transformers. This absence of any proven technique to detect incipient levels of inter-turn winding faults in single-phase transformers has motivated the research of this thesis. In the thesis, firstly, a non-invasive technique for modeling single-phase transformers has been developed which is based solely on the terminal measurements of voltages and currents. The effects of transformer core saturation, non-linearity, hysteresis are incorporated in the model by considering a time-varying magnetizing inductance comprising of any desired number of harmonic components. The coefficients of the magnetizing inductance are computed from the instantaneous values of flux linkage and magnetizing current over one complete cycle. The model is found to replicate the behaviour of the single-phase transformer with an extremely high level of accuracy, under any load conditions for healthy as well as faulty operations. Detailed simulation and experiment based studies have been performed for corroborating the effectiveness of the proposed terminal measurement based modeling technique not only in detecting incipient stages of inter-turn winding faults (involving less than 1% of the turns) but also in estimating fault severity. Also, a non-invasive, online and real-time implementation of the proposed inter-turn… Advisors/Committee Members: Nandi, Subhasis (supervisor).

▼

The single-phase and two-phase versions of AC motors can be modelled by means of the two-axis (d-q) theory with sufficient accuracy when the equivalent circuit parameters are correctly estimated. This work attempts to present a unified approach to the analytical prediction of the electromagnetic torque of these machines. Classical d-q axes formulation requires that the reference frame should be fixed on the frame where the asymmetries arise, i.e. the stator and rotor. The asynchronous torques that characterize the induction motors are modelled in a stationary reference frame, where the d-q axes coincide with the physical magnetic axes of the stator windings. For the permanent magnet motors, that may exhibit asymmetries on both stator and rotor, the proposed solution includes: a series of frame transformations, followed by symmetrical components decomposition. As in single-phase and two-phase systems the homopolar component is zero; each symmetrical component – negative and positive – is further analysed using d-q axes theory. The superposition principle is employed to consider the magnets and rotor cage effects. The developed models account for the most important asymmetries of the motor configuration. These are, from the stator point of view, different distribution, conductors' dimensions and number of effective turns, non-orthogonal magnetic axes windings and from the rotor point of view, asymmetrical rotor cage, variable reluctance, and permanent magnets effect. The time and space harmonics effect is ignored. Test data are compared with the computed data in order to observe how the simplifying assumptions affect the level of accuracy. The analytical prediction methods make possible torque computation according to the nature of the torque being computed, namely, induction, reluctance and excitation (permanent magnet). The results are available for quasi steady-state, steady-state (rated or synchronous speed) and dynamic analyses. All the developed mathematical models can be used in preliminary design for further optimisation and accurate estimation in complex numerical models. Another important feature of the analytical models for single-phase and two-phase AC motors, is that they can be directly implemented in any suitable electrical drives control strategy.

Електротехника - Електричне машине / Electrical engineering - Electrical machines

Употреба електричних машина у електричним возилима и у електромоторним погонима великих снага често се базира на концепту вишефазних машина и претварача. Предмет научне расправе у оквиру дисертације је разматрање, утврђивање и уважавање електромагнетских појава које се јављају у току рада ових машина, а које могу утицати на одабир оптималне топологије статорског намотаја. Постоји потреба за анализом појава које се јављају при раду вишефазне машине, а које утичу на промене њених параметара и перформанси, што је искоришћено као темељ за формирање методологије пројектовања статорског намотаја шестофазне машине. Док су адекватни математички модели вишефазних машина за линеарне услове рада доступни, то није случај са моделима код којих је присутно засићење магнетског кола. У овој дисертацији обрађена је проблематика пројектовања намотаја статора на примеру шестофазне машине. Анализирана је појава засићења магнетског кола при различитим условима напајања, при чему се анализира потенцијална употреба постојећих модела засићених трофазних машина за потребе моделовања засићених вишефазних машина. Код модела шестофазне машине са векторски распрегнутим равнима анализирано је постојање међусобног утицаја између различитих равни при појави засићења магнетског кола, а што је од значаја за развој прецизнијих модела и алгоритама управљања. Дисертација се ослања на аналитичка разматрања, анализу применом методе коначних елемената и експерименталне резултате. Показано је да на засићење на путу главног флукса утичу компоненте струје које не доприносе стварању електромеханичког момента, тј. установљено је постојање међураванског унакрсног засићења, што доводи до потребе за развојем нових модела шестофазних и осталих вишефазних машина, који ће уважити овај ефекат. Поред засићења, анализиране су различите топологије статорских намотаја ради остваривања бољих перформанси шестофазне машине са становишта смањења површинских губитака у ротору. Установљено је да скраћење навојног корака намотаја често не доводи до смањења ових губитака. Као резултат анализе формирана је методологија оптималног пројектовања статорског намотаја шестофазне машине која се базира на основним научним доприносима ове дисертације.

Este trabalho tem por objetivo estudar o acionamento do motor de indução utilizando o método de controle vetorial por fluxo de rotor. Inicialmente, desenvolvido o modelo matemático do motor de indução monofásico transformado o eixo estacionário para que seja eliminada a dependência angular das variáveis do devido à assimetria dos parâmetros do motor. É observado que o motor monofásico pode ser apresentado em configuração bifásica. Em seguida, um estudo de netrização do motor é realizado. O controle vetorial é analisado na seqüência, observando a necessidade de simetria dos parâmetros do motor para que haja um controle o do motor. São considerados dois métodos: controle direto do fluxo de rotor e indireto do fluxo de rotor. Analisa-se, também, o comportamento do controle de simulações numéricas Na seqüência,implementa-se experimentalmente o controle utilizando um processador digital de sinais. Os resultados obtidos mostram que o estudado ao ser aplicado ao motor de indução monofásico apresenta uma boa ta dinâmica para o sistema, tanto para método direto quanto para o método indireto.

The objective of this work is to study the rotor flux vector control applied to a single-phase induction motor drive. Initially, a mathematical model of the motor will be derived. The motor equations will be transformed to the stationary reference frame so that the angular dependency due to the asymmetry of the motor variables is eliminated. Then is discussed that single-phase induction motor can be viewed as a two-phase system. A mathematical model to derive the motor parameters is presented. The next step is to analyze the rotor flux vector control, pointing out the need for a symmetry transformation of the motor parameters. Two control methods are presented: direct rotor flux control and indirect rotor flux control. Theses control methods are validated through numerical simulations. Experimental analyses making use of a digital signal processor are carried out. The results obtained show the good dynamic response when the vector control method is applied to a single-phase induction motor drive system.

Este trabalho propõe um controle de velocidade sensorless aplicado a motores de indução monofásicos. Tem-se por objetivo proporcionar uma alternativa de acionamento com velocidade variável dos motores de indução monofásicos em aplicações residenciais, nas quais estes geralmente operam em velocidades fixas. Para contextualização do tema no cenário atual, inicialmente é apresentada uma revisão da literatura quanto aos acionamentos a velocidade variável de motores de indução monofásicos. A partir da revisão da literatura é desenvolvido o modelo matemático que representa o comportamento dinâmico do motor de indução monofásico e, juntamente com este tópico, a validação do modelo para obtenção dos parâmetros elétricos é feita a partir de ensaios clássicos. Em seguida, é apresentada uma técnica de controle por orientação no campo aplicada a motores de indução monofásicos, com a obtenção de um novo modelo matemático onde essa técnica possa ser aplicada. Além disso, esse trabalho propõe um método de estimação da velocidade rotórica de motores de indução monofásicos a partir de um algoritmo MRAS (Model Reference Adaptive System), baseado no cálculo da potência reativa deste motor. Com isso, são apresentados resultados de simulação para validação da técnica de estimação proposta. O controlador de velocidade escolhido é um PI discreto, que teve sua escolha definida pela simplicidade de implementação. Dois controladores PIs discretos também são usados para o controle das malhas de corrente. Por fim, são apresentados resultados experimentais desenvolvidos em plataforma computadorizada que validam as técnicas propostas, tanto no controle de velocidade com a medição da mesma, como no controle de velocidade sem o uso do sensor.

This work proposes a sensorless speed control applied to single-phase induction motors (SPIM). The objective is to present an alternative for variable speed single-phase motor drives for residencial applications, which operate mostly with constant speed. For contextualization in the actual scenario, firstly a bibliographic review about variable speed operation of single-phase induction motors is presented. After, the mathematical model that represents the single-phase induction motor dynamic behavior is developed, and following, the model validation to obtain the electrical parameters is done with classical experimental tests. Then, a field orientation technique applied to single-phase induction motors is presented, where a new mathematical model is developed for the application of this technique in this motor. Also, this work proposes a method of single-phase induction motors rotor speed estimation using an MRAS (Model Reference Adaptive System) algorithm, based on the calculation of the motors reactive power. So, some simulation results are presented for the validation of the proposed estimation technique. The speed controller used is a discrete PI because the simplicity of its implementation. Two discrete PIs controllers are used for current control. Finally, experimental results obtained in a computer…

Les moteurs asynchrones diphasés sont largement utilisés dans des applications de moins d’un kW, où le prix est un facteur important de choix, en particulier pour les volets roulants. Ces applications, pour des raisons de sécurité, nécessitent une détection précoce des obstacles et donc l’implantation d’un capteur de vitesse. Dans un souci de réduction de coût, une des pistes intéressantes est l’estimation de la vitesse à partir de la mesure des courants et des tensions, de manière à faire l’économie du capteur de vitesse. La première partie de notre travail a consisté à étudier et réaliser différentes alimentations : sur le secteur avec condensateur de déphasage ou par convertisseur statique. Dans une seconde partie, la modélisation du moteur en régime permanent et transitoire et celle du volet (tablier, frein, réducteur) nous a permis d’établir les caractéristiques électromagnétiques du motoréducteur et le comportement mécanique de la charge. Les paramètres de ces modèles ont été identifiés et les résultats analysés. Dans la troisième partie, à partir de ces modèles, différentes stratégies de détection de fin de course du volet sans capteur, d’arrêt sur obstacles ainsi qu’une commande de limitation de couple ont été mises au point et validées expérimentalement. Une carte électronique économique a été réalisée.

The single-phase induction motor is widely used for capacity of less than the kW in applications where the price is an important consideration, particularly for rolling shutters. For safety reasons, these applications require an early detection of obstacles and thus it is necessary to implement a speed sensor. In a preoccupation of cost saving, one tries to estimate the speed on the basis of voltage and current measurements, in order to economize on the speed sensor. The first part of our work deals with the study and realization of different power supplies : Capacitor-run single-phase induction motor or static converter supply. In a second part, the static and transient modeling of the motor and the rolling shutter (shutter, gears and brake) has provided the electromagnetic characteristics of the geared motor and the mechanical behavior of the load. The parameters of these models have been identified and the results have been discussed. In the third part, from these models, different strategies have been devised and validated for detecting the arrival of a rolling shutter on the abutment, implementing a soft stop on obstacles and limiting the torque. A low cost electronic command board has been realized.

▼ Voltage instabilities and subsequent system collapses are considered as growing concerns in modern multiphase distribution networks as they are progressively forced to operate closer to their stability limits due to many factors such as increasing load level, lack of reactive power sources, high installation of single-phase shunt capacitors and reverse action of voltage control devices. System operators must be able to quickly identify trouble spots and take corrective steps to avoid critical voltage collapses. To achieve this, suitable indices must be defined to assess system security and take corrective control actions when predefined thresholds are reached. In this regard, the identification and ranking of weak buses in a power system is an important research area.The existing conventional bus voltage ranking indices are only defined for single-phase and balanced three-phase networks. This thesis proposes a new bus voltage ranking index (VRI) to identify the weakest single-, two- and three-phase buses of multiphase distribution networks. Then, applications of the proposed bus ranking index will be tested for enhancing the voltage stability of unbalanced multiphase distribution networks.In the first part of this thesis, the definition of conventional voltage ranking indices are modified and generalized to also include unbalanced and multiphase networks using symmetrical components. For the first time, the method of symmetrical components is applied to the three-phase voltages computed from three-phase power flow. The new index is defined as the ratio of the (fundamental) positive-sequence voltage at the point of voltage collapse to the positive-sequence voltage at the base-load source. The former voltage level is determined by increasing the active power of all loads while keeping power factor constant until the point of voltage collapse is reached.In the second part of this thesis, the new VRI is validated through the calculation of grid losses and PV curves based on positive-sequence voltage. Extensive simulations of the IEEE 13 and 34 node test feeders are performed using the DIgSILENT PowerFactory to further validate and compare the performance of the new VRI with three well-known conventional ranking indices.In the third part of the thesis, the new VRI is used to identify the weakest three-phase buses in unbalanced three-phase distribution networks. Then, the index is utilized to place compensation devices at the weakest buses of the modified unbalanced three-phase 13 node test feeder to improve voltage stability and increase the maximum loading factor (MLF) under unbalanced three-phase operating conditions.In the fourth part of the thesis, static analyses are carried out to demonstrate applications of the proposed VRI in increasing MLF and improving voltage stability of multiphase networks under unbalanced loading and/or network conditions. Then, dynamic simulations are performed to further validate the accuracy of the proposed VRI and improving voltage stability under dynamic operating conditions.In the…

▼ Sensorless speed estimation in induction machines (IMs) presents an attractive proposition for eliminating the need for physical speed measurement sensors and thus avoiding the associated reliability and cost issues, such as the requirement of extra wiring, careful mounting, maintenance and adjustment. In this thesis, the feasibility of utilising the stator current and power signals to establish spectral search based (SSB) sensorless speed estimation schemes in wound rotor induction machines (WRIMs) operating in extended slip and open-loop controlled conditions is investigated. The research is performed on three different industrial WRIM designs.The thesis first investigates the spectral content of WRIM electrical and mechanical signals with the principal aim of identifying spectral patterns that can facilitate the development of real-time sensorless speed estimation. The examination is based on detailed harmonic models of the considered machine designs as well as experimental results obtained from tests performed on laboratory test rigs. A generalised theoretical analysis of the possible spectral content of machine signals that enables the derivation of closed form analytical expressions linking individual spectral frequencies to rotor speed is also undertaken. The results demonstrate that it is possible to clearly identify speed dependent components in the stator current and power signals and map the boundaries of the narrowbands maximised by these for extended slip and open-loop operating conditions. To enable improvement in attainable real time SSB estimation rates a dichotomous search algorithm real-time spectral processing method was employed for frequency tracking in this research. The algorithm performance is evaluated in real-time tests performed on a measured steady-state laboratory machine stator current and power signals. The results demonstrate that the dichotomous routine provides an inherent advantage in the frequency estimation rate without compromising the estimation accuracy and can therefore enable significant estimation rate improvement in SSB speed estimation algorithms.Novel sensorless speed SSB estimation techniques are then proposed for WRIM operation in extended slip and voltage/frequency controlled conditions. The algorithms utilise the reported analysis of electrical signals and are separately defined for each assessed operation mode and the stator current, phase power and three-phase power signals. It is shown that, in principle, power signal based estimation algorithms can offer an inherent capability of estimation rate reduction. A novel adaptive sliding window algorithm is defined for open-loop operating conditions that enable estimation in a wide operating speed range while minimising the potential for undesirable overlap with PWM harmonics. The proposed algorithms have been verified and their performance limitations assessed in real-time experiments on three different industrial WRIM designs. It is shown that reliable real-time speed estimation in steady-state and transient operating… Advisors/Committee Members: APSLEY, JUDITH JM, Apsley, Judith, Durovic, Sinisa.

Induction motors are widely used as main drives in Textile industries, Machine Tools and Agriculture. More than 60% of electrical energy generated being utilized by induction motors. Any improvement in power factor and efficiency will be cost effective for the nation. The research work is focused to suggest design modifications and efficient operation of three phase induction motor for energy conservation. Efficiency and power factor of an induction motor depends on load current. With regard to the factors of safety and available standard specifications, normally, over rated motors are employed, that lead to poor efficiency and power factor. Double Winding Induction Motor (DWIM) with constructional modification and efficient operation is considered for power factor improvement in this research work. A 3 kW, 415 V, 3-phase DWIM has been designed, fabricated and tested. This motor consists of two sets of identical windings in same stator core. While one set of winding is connected to a three phase supply to work as a conventional induction motor to meet mechanical load, a three phase EMF is induced in the other set of winding, which works as an Induction Alternator (IA). A small three phase load or single phase load may be connected to second set of winding. Since both windings were loaded, in addition to improvement in power factor and efficiency, energy conservation is made possible in this machine. A Microcontroller based control circuit has been designed to operate DWIM in power balancing mode in which the machine is operated at its rated capacity and in energy efficiency mode, it is operated at a load current that corresponds to maximum efficiency. Depending upon the mechanical load on the first set of winding, electrical load is switched to second set of winding such that the machine is operated, based on the mode of selection. An equivalent circuit has been developed for a DWIM from no load test, blocked rotor test and various combinations of electrical and mechanical load on both windings.
