Individual Channel Design for Synchronous Generators

Abstract

In this paper a novel control strategy for a real synchronous generator is presented. It is based on linear, diagonal, low order, minimum-phase, fixed, and stable controllers. The controller was obtained via individual channel design (ICD), a framework that allows analysis and synthesis of multivariable control systems by means of classical techniques based on the Bode and Nyquist plots. The generator is part of a one machine – infinite bus system. A linearised model around an operating point in a rotating coordinate frame is used. The theoretical principles behind this control strategy are summarised for completeness. The results using this novel control strategy are obtained throughout simulations in MATLAB®.
