摘要
微机保护装置运行所处电磁环境恶劣 ,提高其抗干扰性对电网的安全、可靠运行具有重要意义。讨论了电快速瞬变脉冲群干扰的产生机理和特征 ,介绍了相关电磁兼容标准 ,分析了电快速瞬变脉冲群干扰对微机保护装置的影响 。
It is important for power network to improve the immunity of protection equipment running in badly electromagnetic environment. This paper analyzes the generation mechanism and the characteristics of the electrical fast transient burst, and introduces some relative electromagnetic compatibility standards. The influence of electrical fast transient burst on microcomputer based protection equipment is discussed. The restraint methods according to different ports of protection equipment are presented.
