电网中的电力负荷大部分属于感性负荷,在运行中向这些设备提供相应的无功功率。在电网中安装并联电容器等无功补偿设备以后,可提供感性电抗所消耗的无功功率,减少了电网电源向感性负荷提供、由线路输送的无功功率。对无功就地补偿技术进行了探讨。
Most of the power loads in the grid are inductive loads, which provide the reactive power to these devices in operation. The installation of reactive power compensation equipment such as parallel capacitors in the power grid can provide the reactive power consumed by the inductive reactance and reduce the reactive power delivered by the grid power to the inductive load and the line. Reactive compensation in situ technology was discussed.
