论述了输电系统超高压大容量静止无功补偿器(SVC)的改造过程,对河南电网改造后的静止无功补偿器控制策略进行了叙述。通过改造后静止无功补偿器的实际运行结果验证了SVC对稳定河南电网500 kV系统电压、提高系统暂态稳定性的实际作用。
The transformation process of UHV high capacity static var compensator (SVC) in power transmission system is discussed. The control strategy of STATCOM after Henan power grid reconstruction is described. Through the actual operation of the modified static var compensator, the actual effect of SVC on stabilizing the voltage of 500 kV system in Henan power grid and improving the system transient stability is verified.
