| 摘 要： | 介绍了静止无功发生器(SVG)的工作原理、数学模型、控制策略和在风电场的应用情况。通过模拟电网的三相断线故障,测试了SVG的动态响应时间、无功输出容量和系统电压的变化情况。实验结果证明了SVG具有较好的无功输出特性,在系统故障时可以提供较大的无功支撑,从而提高整个电网运行的稳定性。

| Abstract: | The working principle,mathematical model,control strategy and application in the wind farm of static var generator(SVG) are introduced.Through the three-phase disconnection fault simulation of the power grid,the dynamic response time,reactive power output capacity of SVG and the change of the system voltage are tested.The experiment results show that SVG has a good reactive power output characteristics,and provides a big reactive support for the failure system.Thus,it can improve the stability of the entire power grid. |
