摘    要:近年来风力发电发展迅速,风电场逐渐形成了双馈风电机组和直驱风电机组混合运行的格局。由于双馈风电机组与直驱风电机组暂态特性的差异,直驱风电机组对双馈风电机组的短路电流可能产生影响,无法对混合风电场的短路电流进行准确计算。为此,针对双馈风电机组和直驱风电机组组成的混合风电场,建立了混合风电场故障工频等效电路,推导了不同机组影响下的双馈风电机组输出短路电流表达式。通过与单机双馈风电机组短路电流的对比,分析并总结了混合风电场中双馈风电机组短路电流的影响因素和变化规律。针对不同影响因素下双馈风电机组的短路电流,利用时域仿真进行了分析和验证,仿真结果证明了理论分析的正确性。

关 键 词:双馈风电机组  直驱风电机组  混合风电场  短路电流

Abstract:With great development of wind power in recent years, it is a trend that doubly-fed induction generators (DFIGs) and permanent magnet synchronous generators (PMSGs) operate together in one wind farm. Because of the differences between transient characteristics of the DFIG and PMSG, the short-circuit current of DFIG could be affected by the PMSG. The short-circuit current of whole hybrid wind farm can not be calculated accurately. In this paper, fundamental-frequency fault model of hybrid wind farm consisting of DFIGs and PMSGs is built. The short-circuit current of the DFIG considering the influence of multiple different wind turbines is deduced. Based on the comparison with short-circuit current of single DFIG, factors and change law of short-circuit currents of DFIG in hybrid wind farm are analyzed and summarized. Short-circuit currents of DFIG under different conditions are analyzed and verified by time domain simulations.
Keywords:DFIG  PMSG  hybrid wind farm  short-circuit current
