摘要
规划的板桥变电站作为合肥市一环以内第1座220 kV变电站,采用全电缆出线,产生的充电功率较大,而周围变电站均未预留电抗器接入的可能性。考虑在板桥变电站集中配置电抗器以补偿周边电网盈余的无功功率,同时在尽量充分利用线路充电功率的基础上,减少站内电容器补偿容量;并结合电压水平和功率因数的要求,研究合理的无功配置方案,通过计算校验配置方案的合理性。
The planning Banqiao substation is the first 220 kV substation within first-loop of Hefei,all eliciting lines use cable, and produce very large reactive power,while ambient stations don＇t remain the possibilities of installing reactor.In order to compensate the surplus reactive power,this paper considers the scheme of configuring reactor concentrated,and on the base of adequately utilizing the reactive power of lines,decreases the compensated capacity of capacitor in the station.Combining the request of the level of voltage and power factor,this paper studies a reasonable configuration scheme of reactive power,and validates the rationality of scheme through calculating and analyzing.
