基于区域分布的中压配电网无功规划

Planning of Reactive Power in Medium-voltage Distribution Network Based on Local Distribution

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。文章结合某城市中压配电网的电网规划方案。介绍一种综合配电网负荷特性、供电线路类型及长度等因素进行中压配电网无功规划的方法及具体实施步骤。

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, ensuring the distribution network provide high quality electricity to users safely and economically. Combining with power grid planning scheme of the medium-voltage distribution network in one city,a method of reactive power planning for medium-voltage distribution network summing up the characteristics of load, the type and length of power supply line etc. and its implementation steps have been presented.
