静止无功发生器对抗电网负序电压的研究

Countermeasure to Network Negative Sequence Voltage for Static Var Generator

本文介绍了当电网运行不正常,有负相序电压时,静止无功发生器通过软件方法,产生反向的负相序电势来对抗,以维持静止无功发生器的继续运行。本文给出了一个例子,说明如何实现它,以及如何估计本方法的偏差。

The paper introduces a countermeasure to network negative sequence voltage for static var generator by producing counter-negative sequence EMF via software when network is operating abnormally. An example shows how to implement it and how to estimate the deviation of the method.
