Abstract:

This research is concerned with the solid-state power conversion system that interfaces a multi-phase, fault-tolerant, permanent magnet generator to a high voltage DC bus. The generator is being developed for future aerospace application, it has five independent phases, a 3:1 speed range and a one per-unit output impedance.

Abstract:

Equipped with appropriate control strategies, permanent magnet (PM) machines are becoming one of the most flexible types of actuators for many industrial applications. Among different types of PM machines, five-phase BLDC machines are very interesting in fault tolerant applications of PM drives. Torque improvement in five-phase BLDC machines can be accomplished by optimizing their mechanical structure or by enhancing their controlling methods. New current controllers are proposed in this thesis to improve the quality of generated torque under normal operations of five-phase BLDC machines. Pro

Abstract:

It is well known there are three main approaches to maintenance of machinery, namely breakdown maintenance, scheduled maintenance and preventive maintenance. Breakdown maintenance is practised when machines are operated until they fail before maintenance is carried out. This out-of-date maintenance policy is slowly being abandoned by industry. Scheduled maintenance relates to interrupting machinery at regular intervals for the purposes of maintenance and this policy is still being used in many areas even though it is expensive one. The third maintenance policy is that of preventive maintenance

Abstract:

In order to maintain a continuous power suppply, nowadays relays in transmission systems are required to be able to deal with complicated faults involving non-conventional connections, which poses a challenge to the short circuit analysis performed for the data settings of the relay. The traditional sequence domain method has congenital defects to treat such cases, which leads to a trend of using the actual phase domain method in fault calculation. Although the calculation speed of the phase domain method is not so fast and is memory consumable, it perfomrs well when handling complicated fau

It is becoming increasingly common practise to model the impact of faults on fluid flow within petroleum reservoirs by applying transmissibility multipliers, calculated from the single-phase permeability of fault rocks, to the grid-blocks adjacent to faults in produc- tion simulations. The multi-phase flow properties (e.g. relative permeability and capillary pressure) of fault rocks are not considered because special core analysis has never previ- ously been conducted on fault rock samples.

Fault tolerant machine drives are key enabling technologies for safety critical applications such as electric vehicle traction, and aerospace power generation, actuation and propulsion. High performance in healthy conditions and excellent fault tolerance against various faults are required for a fault tolerant drive, however, these two aspects usually conflict with each other. Thus, this PhD study aims to develop a fault tolerant machine drive which exhibits high performance and good fault tolerance, and can be realised in a simple and cost-effective manner.

This thesis explores the impacts and behavior of 3-phase distribution transformers when subject to ungrounded single phase open circuit faults. A simple 3-phase system is modeled using MATLAB Simulink and operation under fault conditions are simulated and studied. Simulation results are confirmed via lab experimentation. Finally, a robust detection and protection method using neutral current injection (as proposed in industry literature) is built and demonstrated.

Abstract:

Three phase induction motors have been intensively utilized in industrial applications, mainly due to their efficiency and reliability. These motors have good properties such as: increased stability and robustness, durability, large power to weight ratio, low production costs and controllability easiness. The most common faults that could happen in the rotor and the stator are: a) short circuit in stator winding, b) broken rotor bars, c) bearing failures, and d) dynamic or static air gap irregularities. These types of faults, are necessary to be identified and categorized, as soon as possible

An estimated 30% of the faults in Induction Machine (IM) are related to its stator.

However, ITSC fault can be avoided by detecting them in advance and then scheduling the maintenance of the IM. This thesis studies two methods for detecting this incipient ITSC fault in a three-phase IM and then estimating the stator resistance unbalance due to the ITSC fault.

The conventional standard three-phase induction motors cannot operate inherently after the loss of a phase. The two-phase operation of a three-phase induction motor cannot supply the necessary performance in terms of torque and output power in applications that require high reliability such as electric traction applications, and electric ship propulsion. Therefore, one of the means to overcome this drawback is the addition of more phases to the motor, which forms the main focus of this thesis.

Abstract:

Les entraînements électriques polyphasés ont acquis une importance particulière ces derniers temps pour leur utilisation dans des applications où la fiabilité présente un intérêt pour des raisons économiques et de sécurité. Cette thèse se centre sur le développement de techniques de commande en mode instantané pour contrôler de manière optimale les machines polyphasées, en analysant leur tolérance dans différentes conditions de fonctionnement, telles que lors de l’atteinte de limites électriques (limites de tension, de courant et de niveau maximum de magnétisation) ou de défauts de type phase

Abstract:

Os motores de indução trifásicos são os principais elementos de conversão de energia elétrica em mecânica motriz aplicados em vários setores produtivos. Identificar um defeito no motor em operação pode fornecer, antes que ele falhe, maior segurança no processo de tomada de decisão sobre a manutenção da máquina, redução de custos e aumento de disponibilidade. Nesta tese são apresentas inicialmente uma revisão bibliográfica e a metodologia geral para a reprodução dos defeitos nos motores e a aplicação da técnica de discretização dos sinais de correntes e tensões no domínio do tempo.

Abstract:

Depuis une quinzaine d'années, l'éolien s'est grandement développé en nombre d'infrastructures et en puissance unitaire mais il reste toujours confronté à un problème de disponibilité de par les nombreuses pannes d'ordre mécanique ou électrique. Le but de ces travaux consiste à concevoir, modéliser et piloter des aérogénérateurs tolérants aux défauts mécaniques et électriques. Pour cela, une structure basée sur une génératrice asynchrone hexaphasée à grand nombre de paires de pôles a été retenue. L'augmentation du nombre de pôles permet de s'affranchir ou de simplifier le multiplicateur, sourc
