Reactive power planning in high voltage power distribution network

配电网无功补偿可以有效地降低网络的有功损耗,提高系统的电压合格率,降低网络运行费用,提高供电质量。配电网无功规划就是在已确定网架的基础上,合理地规划无功补偿装置的容量,减小配电网无功功率流动,保证配电网安全、优质、经济地向用户供电。文章介绍了一种实用的高压配电网无功规划优化方法及其具体实施步骤,对某市高压配电网进行了实际的无功规划分析应用,获得了显著效果,为其他地区高压配电网的无功规划提供了实际参考。

The reactive power compensation of distribution system can efficiently minimize the real power losses and improve voltage level of systems so that the yearly running charge will be reduced and the quality of power energy can be increased. The purpose of reactive power planning in distribution network lies in reasonably determining capacity of the reactive power compensation equipment, decreasing the reactive power flow in distribution network, and ensuring the distribution network provide high quality electricity to users safely and economically. Combining with power grid planning scheme of the high voltage power distribution network, a practical method and its implementation steps are presented, and a practical reference is offered to the reactive power planning of high voltage power distribution network in the other areas.
