无功功率补偿在供配电系统中具有提高电网功率因数的作用,是节能管理中的一项重要的措施.合理规划补偿容量,可以减少电网损失,提高电网质量.目前,杏北油田采用配电线路集中补偿、用电设备分散补偿等四种补偿方式,通过对配电线路集中补偿和用电设备分散补偿进行研究分析,根据补偿效果,得出功率因数的最佳补偿上限为0.9;根据理论计算,杏北油田线路的无功补偿上限为77 169 kvar,提出了6 kV电力线路补偿工作的重心应在单井低压补偿设备的投运上.%The reactive power compensation can improve the power factor of the power grid in the power supply and distribution system,and it is an important measure in energy saving management.Reasonable compensation capacity can reduce the power grid loss and improve its quality.At present,distribution circuit concentrated compensation,electrical equipment dispersive compensation and other two compensation methods are used in Xingbei Oilfield.Through research analysis of distribution circuit concentrated compensation and electrical equipment dispersive compensation,and according to compensation results,the optimum compensation upper limit of power factor is 0.9;and according to theoretical calculation,it is known that the reactive power compensation upper limit of cables in Xingbei Oilfield is 77 169 kvar,then it is put forward that the key of 6 kV compensation work should be the operation of low voltage compensation devices for the single well.
