摘　　要：运用连续潮流计算的PU曲线法,对基于直驱永磁风力发电机(D-PMSG)并网风电场参与电力系统电压控制调整进行了研究。针对风电接入地区电网电压出现偏高或偏低的运行工况,通过调整D-PMSG网侧变频器的不同控制策略,使D-PMSG并网风电场发出或吸收一定的无功功率,最终使风电接入地区的电网电压在允许的偏差范围内,符合电网的相应规程。通过对新疆某地区电网进行仿真计算,根据绘制的D-PMSG构成的风电场参与电网电压调整控制前和控制后风电场升压站、公共接入点及地区电网重要变电站的PU曲线结果表明:通过调整D-PMSG风电场的控制策略,能有效改善含风电地区电网的静态电压稳定问题。The PU curves method was applied to research on the D-PMSG wind farm participating in regulating voltage stability of power system. When the voltage of wind farm regional power network appears high or low, by changing different controllable modes of the grid-side converter of D-PMSG, let the D-PMSG wind farm discharge or absorb a certain reactive power, at last the voltage stability of regional power network can make the voltage be in normal range . By means of a certain regional power network located in Xinjiang uygur autonomous region, the PU curves of at point of common coupling, key buses are plotted before and after wind farm participating in regulating voltage stability of power system. Conclusion is as follows, by changing different controllable strategy, it enhaces the level of static-state voltage stability of power system effectively.
