本文对配电网中无功补偿并联电容器组投切时间进行理论分析,在理论分析的基础上,采用后台计算机的监控系统中实现的电压无功综合控制方法,分析了无功控制(VQC)原理,给出了相应的调节策略,从而减少了电容器组投切时所引起的涌流和过电压,延长了电容器组的寿命,保证了变电站用户端的电压接近额定值,对提高全网电压质量有着现实重要意义。 Based on the theoretical analysis, this paper analyzes the reactive power control (VQC) method based on the voltage and reactive power integrated control method in the monitoring system of backstage supporter. Principle, the corresponding adjustment strategy is given to reduce the inrush current and over-voltage caused by switching capacitor banks, prolong the life of capacitor banks and ensure that the voltage at the subscriber terminal of the substation approaches the rated value, thus improving the voltage quality of the entire network Reality is important.
