Behavior Analysis Of Asynchronous Wind Turbine In Presence Of Static Synchronous Compensator Operating With Fuzzy Logic Voltage Controller

Abstract : The aim of this paper is to discuss and demonstrate how a Static Synchronous Compensator (STATCOM) is used with a Single Input Fuzzy Logic Controller (SIFLC) to improve voltage profile and stability of an asynchronous wind turbine. In the literature, it is well known that reactive power management is the greatest challenge in wind turbine based on a three-phase Self-Excited Induction Generator (SEIG). Any variation of wind speed or load causes a variation on the needed reactive power and thus a voltage fluctuation. Flexible AC transmission (FACT) device such as STATCOM become then a necessity to prevent voltage instability and hence voltage collapse at the point of common coupling (PCC). The performance of the proposed compensator can be significantly improved when combined with a SIFLC. The present document traits so the modeling of the power system, the simulation results, the control scheme and the design of the proper SIFLC.
