摘要
随着电网负荷的日益加重,许多变电站都需要加装无功补偿装置。经济合理地配置无功补偿设备,对提高输送能力和降低电网损耗具有重要意义。在深入研究变压器和线路无功损耗产生机理的基础上,结合变压器和线路的实际运行情况,提出220 kV变电站无功补偿容量的实用计算方法。并利用该计算方法计算了山东电网某220 kV变电站需要的无功补偿容量。
As the load increase in the power grid, the reactive power compensation devices should be added in many substations. Economic and reasonable allocation of reactive power compensation equipment to improve transmission capacity and reduce power loss is important. Based on the study of losses on the transformer and line, combining with the actual operation situation of transformer and line, and 220 kV substation reactive-power compensation capacity of practical calculation method is provided in this paper. By this way, the reactive compensation capacity needs of a 220 kV substation in Shandong Grid have been calculated.
