Computer Simulation of Synchronous Machines

11.1  Introduction

While a motor or generator runs at steady state the vast majority of time, it is the brief instant where a transient occurs when most machines fail. There exist scenarios where the models leading up to this chapter fail to provide the needed accuracy, primarily because speed varies in such a manner that Park’s equations remain non-linear. In this case a full simulation of the differential equations is required. The method by which one goes about solving these equations varies widely. This chapter will describe an approach based on using MATLAB. The solutions will be obtained using the hybrid flux linkage variable ψ introduced in Chapter 3. The hybrid flux linkage has units ...
