针对风力发电机在直接并网方式下产生的暂态冲击电流过大的问题，提出了一种削弱异步发电机并网暂态的新方法，在异步发电机Y。型接线定子中性点串入一电阻，三相顺序延时合闸并网。理论分析、仿真和模拟实验结果表明，该方法同三相线路中分别串联电阻的方法相比在并网瞬间冲击电流的抑制效果上几乎是等效的。而由于该方法只需要一个电阻及旁路开关，因此比传统的三相串入电阻法更加经济。文章还通过理论分析推导出了中性点电阻的最佳取值表达式，以用于该方法的具体实施。“,”In allusion to intense transient current impaction due to direct grid-connection of induction wind turbine generator, a new method to suppress such a transient current impact is proposed, that is, a resistance with a parallel by-pass switch is connected in series into the grounding circuit of wye-connected stator windings and three phases of the induction generator are connected to power grid in sequence with time-delay. Results from theoretical analysis, digital simulation and simulation experiment show that as for the effect of suppressing current impact at grid-connecting moment the proposed method is almost equivalent to traditional method of connecting three resistances in series to each phase, however the proposed method only need a resistance and a by-pass switch connected in parallel with the resistance for an induction generator, so the proposed method is more economical.
