| 摘 要： | 用静止无功补偿器(SVC)和可控硅控制串联补偿器(TCSC)进行联合补偿,以提高异步风机风电场的暂态电压稳定性。在Matlab/Simulink中搭建了风电场及相关电网模型,通过仿真计算验证了SVC和TCSC对异步机风电场与电网暂态电压稳定性的作用。研究结果表明:在风速随机波动的情况下,SVC能动态地补偿无功功率,保持系统的暂态稳定性;当接入电网发生三相短路的大扰动故障时,TCSC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。

| Abstract: | Static var compensator(SVC) and thyristor controlled series compensator(TCSC) were united to improve the transient voltage stability of the asynchronous wind farm in this paper.And the related structure model of the wind farm power system is built in Matlab / Simulink.The contributions of SVC and TCSC to transient voltage stability of the asynchronous wind farm and power grid are verified by the simulation.The results showed that: when the wind speed is in random fluctuation,SVC can compensate reactive powe... |
