Reactive power analysis and control of doubly fed induction generator wind farm

Power relations of doubly fed induction generator (DFIG) wind power generation system are analyzed. Based on this, a method is proposed to calculate the reactive power limit. Furthermore, the reactive power control of DFIG wind farm is studied and the control scheme is provided to exert the reactive power dealing capability of wind power system. A reactive power compensation strategy for the local user using DFIG wind farm and the distribution algorithms of reactive power demand are given. Simulation results are provided to verify the proposed theory.
