Abstract

According to the random variation characteristics of wind energy and the fluctuation of dynamic reactive power regulation of DFIG along with the variation of active power, this paper proposes a new control strategy for reactive power and voltage. In this strategy, the scheme of switching of capacitor bank is pre-performed based on the predicted wind power, then based on the analysis on the PQ curve of DFIG, by regulating the reactive power of wind farm in real time with SVC; it implements the reactive power and voltage control. Therefore, this improvement can enhance voltage quality and reduce capacitor responding times. The simulation results of a real time wind speed disturbance wind farm system show that the control strategy is effective and feasible.

Key words

doubly-fed induction generator (DFIG) / coordination control / switching of capacitor bank / static var compensator (SVC)
