Development of Fuzzy Excitation Control System

Abstract

Power system stability is essential to reliable and economical operation of power system. The quick-response excitation control with PSS is used as a power system stability improvement measure at generator. This method, however, is not always sufficient to apply in a wide operation range of power system configuration, load flow, and so on.
This paper includes results of experiments of fuzzy excitation control system on AC/DC Power System Simulator of CRIEPI. This control system is verified to improve power system stability and has better performance than the conventional excitation control on a one and two machine to infinite bus system.
