کنترلر هماهنگ مبتنی بر فازی برای پایداری سیستم قدرت و تنظیم ولتاژ

This paper deals with the design of a fuzzy based coordinated controller to prevent an electric power system losing synchronism after a large sudden fault and to achieve good post-fault voltage level. The developed controller has a fuzzy logic unit (FLU) which, accepts change in terminal voltage and speed deviation as its inputs and generates the required weightage for the transient controller and voltage controller. The performance of the proposed controller is compared with those existing control switching coordinate controller. The simulation study is carried out for the configuration of a single machine infinite bus power system.
