摘要
】在大型电力电子装置的供电系统中，往往存在着大量的谐波干扰，致使功率因数难以测量、无功功率不易补偿。为此，本文提出了一种新的高压无功功率自动检测补偿系统。通过对电流波形进行数字滤波，准确地确定了功率因数。同时，采用非线性控制技术，较好地解决了无功功率的自动补偿问题。试验证明，该系统稳定可靠，节能效果明显。
There are a lot of harmonic disturbances in the power supply system of large scale power electronics setup.The harmonic disturbances result in difficulties to measure the power factor and to compensate the reactive power.This paper presents a new automatic measurement and compensation system of high voltage reactive power.The power factor can be measured accurately by digital filter of current waveforms and the reactive power can be compensated by non linear control.Experiments have proved that the system is stable and reliable.
