Coordinated Fuzzy Logic Control for Series Capacitor Modules and PSS to Enhance Stability of Power System
Abstract
This paper presents an application of a fuzzy logic control scheme for switched series capacitor modules to enhance overall stability of electric power systems. Through the signal conditioning of the measured real power flow at the location of the series capacitor modules, the phase/speed state of the electric power system is obtained to determine the number of capacitors energized at the state. The switching rules ate quite simple so as not to give heavy computation to the micro-computer utilized for the real time switching control of the series capacitor modules. A multimachine system is used to demonstrate the efficiency of the proposed switching control scheme, and coordination with power system stabilizers is considered.
Keywords: Fuzzy logic control scheme, Real time control, FACTS, Series capacitor modules.
