摘要
阐述母线保护在电力系统中的重要作用,分析目前各类母线保护各有哪些优缺点,以及未来母线保护的发展方向。针对现在运用的不同母线保护,分析其工作原理,在实现母线保护的过程中运用了哪些型式的装置及其各自的特点和改进方法等。
The characteristic of bus protections used now are analyzed, what its advantage and disadvantage, important action in power system and development direction in future are explained. Aimed at different bus protection used now, what their operation principle, which relay protections would be used in its carrying out process, the features and the improved method of which also are introduced.
