A Basic Study of Fuzzy-Logic-Based Power System Stabilization with Doubly-Fed Asynchronous Machine

This paper investigates the function of DASM (doubly-fed asynchronous machine) with emphasis placed on its ability to the stabilization of the power system. P (active power) and Q (reactive power) compensation from DASM can be determined by fuzzy logic, and regulated independently through secondary-excitation controlling. Simulation results by EMTP show that such system can restore the power system to a normal operating condition rapidly even following severe transmission-line failures. Comparison studies have also been performed between a conventional controller and proposed fuzzy-logic controller
