Investigation of Switched Reluctance Generator Characteristics

Abstract

The current thesis presents an investigation for the performance and characteristics of switched reluctance (SR) machine in its generating mode. The effect of different operating parameters has been considered. The performance of switching reluctance generator is studied when connected to a common network and when feeding an isolated load,

The thesis provides a survey about. switched reluctance machine system components and its performance .in both motor and generator modes of operation. The differences between motor and generator modes are discussed on the basis of energy conversion principles to achieve clear understanding of the generator operation.

Switched reluctance machine magnetization characteristics are inherently nonlinear. The available models of switched reluctance machine are numerical in nature. A software development kit (SDK), oriented towards switched reluctance system simulation, is designed and implemented in C++, it implements object oriented programming (OOP) technique. The SDK contains software libraries to simulate SR •machine with different models, different drive topologies and different types of electric supplies and loads. The developed SDK is fully compatible with Microsoft Foundation Class (MFC) library and designed to be fully extendable and modifiable for future work.

The software package is developed undr:r Microsoft Windows operating system. It implements graphical user interface (GUI) based on multi document interface(MDI). Such package is efficient to study and compare the design and performance of different machine and drive configurations.

The performance of switched 'reluctance generator based on the nonlinear magnetization characteristics is extensively studied.
