COMPARISON OF USING SVC AND STATCOM TO PROVIDE REACTIVE POWER FOR A GRID-CONNECTED WIND POWER PLANT TO STABILIZE THE OUTPUT VOLTAGE DURING STARTUP AND FAULT CONDITIONS

In this paper our study highlights the stability of wind farms with Fixed Speed Induction Generators (FSIG) during startup and fault conditions. Also, focusing at the use of Static Var Compensator (SVC) and Static Synchronous Compensator (STATCOM) to improve the performance of wind farms to investigate. Due to the nature of an Asynchronous Generator during starting and fault condition and because of the large amount of slip of rotor, generator consumes a large amount of reactive power that it causes variation in small networks and changing in voltage level profile. Here in this exercise we illustrate the necessity of using compensators using previous works and then by using of wind turbine model in MATLAB we applied it in our network and simulated this network with SVC and STATCOM, and finally we discuss output diagrams.
