Power Quality Improvement using Fuzzy controlled Statcom
Keywords:
Voltage stability, FACT, STATCOM, Fuzzy logic controllerAbstract
A static synchronous compensator (STATCOM) is one of the FACTS devices used to improve the power
quality of the power system. In this paper a mamdani based fuzzy logic controller is designed. The inputs to the fuzzy logic
are the alternator speed i.e. w and its derivative i.e. dw/dt and the output is the firing angle α of the voltage source
converter. The proposed controller is tested on two machine system using Matlab Simulink Environment. The Results are
compared with conventional PI STATCOM Controller.
