摘　　要：风能具有随机性和间歇性,大规模风电场接入电网时会对系统的稳定性产生一定的影响。建立了风力发电机组模型,仿真分析了利用STATCOM改善风电场(由变桨距定速异步感应发电机组成)的静态和暂态稳定性。仿真结果表明,STATCOM可以有效地改善风电场的稳定性,在系统故障后提供无功支撑,提高了风电场的低电压穿越能力。Due to the stochastic and intermittent characteristic of wind power,lager--scale wind farm integration has a great impact on the stability of power system. A mathematical model of wind power generation sets is established to research voltage stability enhancement of wind farms by using STATCOM. The simulation results show that STATCOM provides reactive power support to improve the voltage stability of wind farms after the faults are cleared,and improve the low voltage ride-through capability.
