摘要
电力系统无功就地补偿器是电力供电系统中重要的调节设备,在系统中可以起到提高电网功率因数的作用,同时它也能够降低供电变压器以及输送线路的损耗,提高供电效率,改善供电运行状态。该设计以AT89C52为核心,采用互感器对电网中的电压与电流的相位角进行测量,并根据设定的阈值来确定是否需要向电路中投切电容。经过试验证明,该设计方案能够实现自动、快速、精准的无功功率补偿,有效地改变功率因数使其达到理想阈值,从而减小电力输、配电的损耗,提高供电质量,具有较好的实用价值。
Reactive power compensator in power system is an important regulating equipment in power supply system,which can improve the power factor of power grid,reduce the loss of power supply transformer and transmission line,improve power supply efficiency and improve power supply operation status.This design takes AT89C52 as the core,and uses transformer to measure the phase angle of voltage and current in the power grid,and determines whether it is necessary to switch capacitors into the circuit according to the set threshold.Experiments show that the design scheme can realize automatic,fast and accurate reactive power compensation,and effectively change the power factor to reach the ideal threshold,thus reducing the loss of power transmission and distribution,improving the quality of power supply and having good practical value.
