企业配电系统谐波污染及治理

Enterprise Distribution System Harmonic Pollution and Its Treatment

现代工矿企业因大量使用各种非线性负载,其配电系统中势必会产生较为严重的谐波污染,对变压器、电动机、电容器等电气设备的使用效率和寿命造成影响,从而给电网稳定运行和企业正常生产带来了潜在的威胁,需要加大谐波治理力度,提升电网电能质量。通过正确选用无源滤波、有源滤波、混合滤波等技术,以及合理采用集中滤波、分散滤波和就地滤波的方式,能有效抑制各类谐波,改善供电质量,保证企业配电系统安全稳定运行。

Modern industrial and mining enterprises inevitably generate serious harmonic pollution in their power distribution systems due to the extensive use of various non-linear loads,thus affecting the service efficiency and life of electrical equipment such as transformers,motors and capacitors.Therefore,it poses a potential threat to the stable operation of the power grid and the normal production of the enterprise.It is necessary to increase the intensity of harmonic control and improve the power quality of the power grid.Through the correct selection of technologies such as passive filtering,active filtering and hybrid filtering,as well as the rational use of centralized filtering,decentralized filtering and local filtering,various harmonics can be effectively suppressed,power supply quality can be improved,and the safe and stable operation of the enterprise power distribution system can be ensured.
