目前国内配电变电站中电压与无功控制的主要手段是调节有载调压变压器的分接头和并联补偿电容器的投入量,以保证电压在规定的范围内,并尽量减少电网中无功的传输。本文首先分析了变电站电压无功控制的基本原理,然后全面地阐述了目前国内外变电站电压与无功控制策略的研究状况,分析了各种控制策略所存在的问题,最后提出了变电站电压无功控制的改进方向。
At present, the main means of voltage and reactive power control in distribution substations is to adjust the input amount of tap and shunt compensation capacitor of on-load tap-changer to ensure the voltage is within the specified range and minimize the reactive power transmission in the power grid . This paper first analyzes the basic principles of substation voltage and reactive power control, and then comprehensively expounds the current research situation of substation voltage and reactive power control strategies at home and abroad, analyzes the problems existing in various control strategies, and finally puts forward the substation voltage reactive power Control of the direction of improvement.
