Reducing Voltage Fluctuations in Wind Turbines by SVC Method

Abstract:

Today because of increasing wind generation in the power systems, voltage variations are critical in power quality of grid combination of wind energy. This paper presents a Static Var Compensator (SVC) as an efficient choice for the reactive power regulation of wind turbines to decrease voltage fluctuations, and the proposed modulation is performed for the cases with and without SVC. The simulation showed the effective influences of the SVC on the voltage characteristic with the unexpected changes in the voltage magnitude.
