云南电网无功优化配置方案

Configuration Scheme on the Yunnan Power Grid Reactive Power Optimization

在合理电网规划和电源规划的同时,进行无功规划是维持电网电压稳定和保证电能质量的不可缺少工作。根据"十二.五"云南电网规划,使用BPA软件对云南电网"十二.五"进行分层分区无功平衡分析。利用灵敏度分析找出无功补偿敏感点,从动态仿真角度研究了无功补偿类型。从优化角度论证了无功配置能够满足电网无功优化运行。提出的无功优化配置,对云南电网"十二.五"无功规划具有良好的指导意义。

While reasonable network planning and power planning, reactive planning is indispensable to main-tain the grid voltage stability and ensure power quality. Based on the Yunnan Power Grid ＂12th Five-Year＂ Plan- ning, BPA is used to analysis stratified and partitioned reactive power balance, and used the method of sensitivity analysis to identify the sensitive point of reactive power compensation. Then from the dynamic simulation point of view the type of reactive compensation is studied, and from optimization point of view it demonstrates the reactive configuration which is able to meet the reactive power optimization run. The proposed reactive power optimal alloca- tion is a good guidance to the Yunnan Power Grid ＂12th Five-Year＂ reactive power planning.
