一种适用于母差保护的CT饱和判据

CT saturation criterion suited for busbar differential protection

母线是发电厂和变电站的重要组成部分 ,一般均装设母线保护 ,而母线保护工作的可靠性将直接影响发电厂和变电站工作的可靠性。如何防止母线保护在外部故障CT饱和时误动 。

Busbar is an important unit of power system and the reliability of busbar protection will directly affect the reliability of generating plant and substation. How to prevent the busbar protection from maloperation in saturated CT and external fault is still a question to be discussed.
