摘　　要：配电网无功补偿可以有效降低网络有功损耗,提高供电质量,降低网络运行费用。然而,规划态的配电网数据收集困难,特别是很难准确得到几年后系统的自然功率因数,使得规划期无功优化比较难于解决。根据规划导则首先求得现状年馈线的合理无功补偿度,然后基于该补偿度对规划期馈线进行无功补偿。实例计算分析表明了规划态配电网无功补偿估算方法的简洁和实用。Reactive power compensation of distribution networks can effectively reduce the power loss,improve power supply quality and reduce network operating cost.However,it is difficult to obtain the data of the planned distribution network,especially the power factor of system loads.Thus it is difficult to solve the problem of reactive power optimization in planning stage.The paper proposes to obtain a reasonable degree of reactive power compensation of the existing feeders according to planning guideline,and then to make a reactive power compensation for the planned feeders based on compensation degree.Case study indicates that the proposed method is simple and practical for estimating the reactive power compensation of planned distribution network.
