摘　　要：利用线路故障临界切除时间来表征电力系统暂态电压稳定性的量化指标,采取动态时域仿真法对WSCC3机9节点算例系统与基于直驱机组并网风电场接入该算例系统的暂态电压特性进行了仿真分析,研究结果表明,接入直驱机组风电场后算例系统的线路故障临界切除时间要比原算例系统的线路故障临界切除时间要长,因此,基于直驱机组风电场的接入算例系统能较好地改善原系统的暂态电压稳定性。The transient voltage stabilities of a three-synchronous-generator and nine-bus power grid integrated with or without Direct-driven Permanent Magnet Synchronous Generator （D-PMSG） are simulated by dynamic time-domain method and compared by taking the fault critical clearing time as the quantitative indicator of transient voltage stability of power system. The results show that the fault critical clearing time of grid integrated with D-PMSG is longer than the grid without D-PMSG, and so the integration of D-PMSG into grid can improve the stability of grid.
