摘　　要：提出了以微机线路保护为基础实现方向式母线保护的方法，它工程造价低，构成简单，不受ＣＴ饱和等因素的影响。方向式母线保护能较好地适应厂站自动化特别是继电保护下放的需要，同时也为超高压电网重要厂站母线保护的双重化提供了新选择。A new method to realise directional bus protectionbased on microprocessor line protection is introduced. It is of low engineering cost, simple construction and not affactec by CT saturation. The directional bus protection is well available to the requirement of substation automation, especially distributed type relaying, meanwhile provide a new choice for doubling of bus protection in important substation of UHV power network.
