基于开环控制的启备变电源系统无功补偿控制策略研究

摘要

In power system, static var compensator plays an important role in improving line power factor and the quality of system voltage, but when with the startup power source the static var compensator can hardly have a good compensation effect. The control strategy of static var compensator in startup power source was studied, a method based on open loop control was put forward and the scientificity and rationality of the control strategy was proved through simulation.%在电力系统中，无功补偿装置主要用于提高线路功率因数，改善系统电压质量的作用，但是，在含启备变供电环境下，无功补偿装置想要取得良好的补偿效果就极其困难。对含启备变系统中无功补偿装置的控制策略进行了研究，提出了一种基于开环控制的方法，并通过仿真，验证了控制策略的科学性与合理性。
