摘　　要：220 kV变电站在农村电网是重要的上级电源点,通过下级变电站供带负荷,在城市电网直接供带周边负荷,其电压水平高低对于下级电网及用户电压质量起着重要作用。科学、合理地选择变电站无功补偿装置,将有助于保障各级电网电压处于适宜水平,减少网损,保证供电质量。首先明确无功计算原则与步骤,从无功平衡、调相调压计算及电压波动校核三个方面来选择220 kV变电站无功补偿装置,从而指导工程设计与运行。In the rural power grid,220 kV substation is the key source of power for lower substation,and in the urban power grid,220 kV substation directly supply power for surrounding customers,which plays an important role in the power quality of the lower power grid and users.The scientific and reasonable selection of reactive power compensation devices for substations will contribute to qualified voltage of power grids at all levels,lower power loss and power quality.In this paper,it clarified the principles and steps of reactive power calculation,then select reactive power compensation device from three aspects:reactive balance,power flow calculations and voltage fluctuation check,so as to provide guideline for the engineering design and operation.

关 键 词：无功补偿 供电质量 网损
