摘　　要：由于清远地理位置的特殊性 ,小水电比例较大且远离负荷中心 ,使得清远电网丰、枯水期电网运行方式有很大的不同。从无功补偿的原理 ,分析了清远电网电压偏高的原因。采用灵敏度分析的方法 ,计算出清远电网无功补偿的容量及补偿地点 。Due to the large proportion of small sized hydro power in Qingyuan power system as well as the far location from load center,the operation mode is far different during the raining seasons and dry seasons.The reasons of the high voltage in Qingyuan power system are presented in this paper.The capacity and sites of reactive load compensation in Qingyuan power system are given using the sensitivity analysis.After reactive compensation,the voltage of the power system is improved.

关 键 词：无功功率 无功补偿 丰水期 枯水期
