摘要
平凉电网的无功、电压存在的问题主要是华亭电网的无功潮流分布不合理和电压偏高问题,为了切实有效解决电压问题,查找原因,根据平凉电网4种典型方式,进行无功优化计算,分析平凉电网无功负荷分布情况和无功补偿情况,降低华亭电网110kV系统电压是此无功电压解决方案。
Existence of reactive power in the Pingliang power grid can be attributed to the unreasonable distribution of reactive powertidesandhighervoltageexistingintheHuatingpowernetwork. To find out the causes and to address the problem effectively, the reactivepoweroptimizationcomputationisdoneaccordingtothefour typical modes of the Pingliang power grid, analyses are done for the distribution and compensation of the reactive power in the grid. It is concluded that lowering the system voltage of the 110 kV Huating networkbetherightsolutiontosolvethereactivepowerissue.
