摘 要: | 补偿无功功率将降低供电系统的功率损耗和电能损耗,减少变压器和线路中的电压损失和提高发供电设备的利用率。针对并联电容器的安装地点不同、控制方式不同以及安装点与功率因数考核点不同,提出各种不同的无功功率补偿容量和功率因数的计算方法。结果表明,补偿后变压器损耗有所下降,变压器一次侧平均功率也有所下降,对应的功率因数上升了,证明了其计算方法的正确性。

Abstract: | Compensation for reactive power would lower down power supply's power loss and electricity energy loss,and reduce the voltage loss in transformer and lines and raise utility rate of generator and power supply equipment.Calculation methods were raised for different reactive power compensation capacity and power factor aiming at different installation of parallel capacitors,control method and different in site and power factor examining site.The results show that after compensation,transformer loss is somewhat reduced,transformer primary average power is also reduced and the corresponding power factor is raised,proving the correctness of its calculation method. |
