摘　　要：电力系统的负荷需要消耗大量的无功功率,而无功功率平衡要满足众多的接点电压,这就需要分级分层就地平衡。地区电网的电压无功控制,主要是控制其管辖范围内的各级变电站,使电网的电压合格,并实现无功就地平衡,降低网损,节约能源。这样,就要大力推动电压无功综合控制装置(VQC)在变电站的广泛应用,为此,对电压无功综合控制装置的实现方式、控制原理、控制方式以及控制策略进行了阐述,并提供了在变电站实际应用的工程方案。The load of power system entails great consumption of reactive power. To satisfy multitudinous nodal voltages, reactive power should be balanced hierarchically and locally. The voltage and reactive power control for regional power grid mainly controls the substations under it to ensure voltage quality of the grid and realize local balancing of reactive power, thereby reducing network losses and saving encrgy. So the widespread application of the voltage and reactive power integrated automatic control （VQC） system in substations should be actively promoted. This paper expatiates on the realization way and the control principle, mode and strategy of VQC, and describes two schemes for applying VQC in substations.
