摘要
谐波谐振严重危害配电网的安全可靠运行,对配电网来说,抑制谐波是很有必要的。主要研究了低压无功补偿谐波抑制,根据低压无功补偿谐波放大抑制原理,对补偿电容的选择进行深入研究,并分别针对单台抽油机无功补偿对谐波谐振的影响和渤南线所有抽油机无功补偿对谐波谐振的影响。通过理论研究与仿真分析,得出有效的低压无功谐波放大抑制措施,有效抑制谐波对配电网的影响,提高配电网运行可靠性。
Harmonic resonance seriously affects the safe and reliable operation of distribution network.It’s very necessary to suppress the harmonics in oilfield power grid.Based on the principle of harmonic amplification suppression,the selection of compensation capacitor voltage is studied in depth.The influence of single pumping unit and all pumping units reactive power compensation on harmonic resonance is also researched and effective suppression measures for low voltage reactive power harmonic amplification are obtained to improve the operation reliability of oilfield distribution network.
