Among the Static Synchronous Compensator (STATCOM) objectives, the correction of power factor, as well as the protection of sensitive loads against voltage swell/sag voltage. The STATCOM acts as a voltage source inverter, which is connected in shunt with a sensitive load and controlled to generate the required compensation reactive power. Only power-factor correction is the concern of this paper, which will mean operating the STATCOM as Var compensation mode. The proposed system is founded by the PLL concept in a wind energy conversion system (WECS). The planned WECS is formed by permanent magnet synchronous generator (PMSG) wind turbine system connected to the grid through Static Synchronous Compensator. The ability of fuzzy logic to handle rough and unpredictable real world data made it suitable for a wide variety of applications, especially, when the models or processes are too complex to be analyzed by classical methods. This paper investigates the application of a fuzzy controller for controlling the DC capacitor voltage under steady and transient condition. Simulations using MATLAB / SIMULINK are carried out to verify the performance of the proposed controller.
