双馈电机风电场电压协调控制策略

为增强并网风电场的电压稳定性,提出了一种变速恒频双馈风机组与风电场无功补偿装置??静止同步补偿器的协调控制策略.该策略充分利用了DFIG网侧换流器、定子侧的无功发生能力,有效提高了风电并网点电压的暂态水平,并加速了电压的恢复过程.在DIgSILENT/Power Factory建立了仿真模型,仿真结果验证了该控制策略的有效性.;In order to enhance the stability of the voltage of grid-connected wind farm, a coordinated control strategy of Doubly-fed Induction Generator(DFIG) and wind farm with FACTS device Static synchronous compenstator is proposed. In this strategy, DFIG grid-side converter and the stator side reactive power generate ability are utilized, the Point of Common Coupling(PCC) transient voltage quality is improved, and the transient voltage recovery process is sped up. The proposed coordinated control strategy is simulated by DIgSILENT/Power Factory, and the simulation results show that the method is correct and feasible
