摘要
安装并联电容器是提高电力系统功率因数、减小线路损耗及电压降落的常用方法,分析了电网中谐波的存在会增加电容器的介质损耗,并可能使系统发生并联谐振,放大谐波电流,危及电容器及系统的正常工作,为此,提出了避免谐振的对策。
The parallel capacitor is often used to improve the power factor, diminish the line loss, and prevent voltage drop. It is pointed out that harmonic in power systems will increase the dielectric loss of capacitors and can cause parallel resonance in the system. Countermeasures to prevent the parallel resonance are proposed.
