摘要
电压稳定性问题是风电场并网运行中普遍存在的现象。建立了静止无功补偿器和固定电容器结合的控制模型及控制策略。重点分析SVC补偿容量大小、控制器增益K大小对提高风电场电压稳定性的作用;当接入电网发生三相短路的大扰动故障时,仿真分析表明SVC能够有效地恢复机端电压,提高了风电场的低电压穿越能力。
Voltage stability issues is a widespread phenomenon integration on power system in the wind farm. In this pa- per, establishing control model and control strategy of combining a static var compensator and fixed capacitors in PSASP. Focused analysis SVC compensation capacity sizes, the controller gain k size in the role of wind farm voltage stability. The short circuit of Three-phase occurred when large disturbance faults in grid, The simulation analysis shows that SVC can effectively restore machine terminal voltage, improving the capacity of low voltage ride through in wind farm.
