摘要
随着微机型继电保护的广泛应用,继电保护装置和二次回路的电磁干扰问题越来越引起电力工程界的重视。该文分析了电力系统中常见的电磁干扰,讨论了继电保护的常见干扰源、耦合途径和抑制手段,对实际工程中发生的两起继电保护电磁干扰问题进行了深入的研究,分析了干扰产生的原因,提出了相应的现场处理意见,具有一定的理论意义和工程实用价值。
Along with the widely application of microcomputer protections, the electromagnetic interference problems of protection devices and circuits has aroused more and more interests. The common electromagnetic interference in power systems is analyzed and the interference sources, coupling approaches and the suppress ways are discussed as wcll. Two electromagnetic interference cases in field are analyzed. The corresponding suggestion is also presented with theoretical analysis and engineering application value.
