Damping of Electromechanical Oscillations in Multi-Machinery Power System with Various Types of Excitation Controller

Abstract

The paper cites investigation results of electromechanical oscillations in the power system where synchronous generators are equipped with various types of excitation controllers in the presence or absence of system stabilizers. Influence of every controller types on oscillation processes in the power system has been shown in the paper. The paper proposes an approach of optimum selection of setup excitation controller parameters while having system stabilizers. A complete scheme of the «Azerenergy» system has been taken as an example for an analysis of electromechanical oscillations and an influence of excitation controllers on them. Synchronous generators of the system are using excitation controllers of dramatic effect and СДП1- and UNITROL-types having a system stabilizer
