| 摘 要： | 作为高压母线的专门保护,BP-2B复式比率差动以动作可靠、灵敏度高、整组动作时间短而著称,在福州电业局得到了广泛的应用。为了简化复式比率差动调试方法、提高现场工作效率,本文深入分析了复式比率差动判据,推导了一种新的复式比率差动调试方法,并通过实践证明了这种方法的可行性和有效性。

| Abstract: | As special protection of high voltage bus,BP-2B duplex ratio-differential protection is famous because its action time is short and its sensibility is high,so it is used in Fuzhou Power Supply Bureau widely.In order to simplified the debugging method and increase the job ratio,we analyse the criterion of duplex ratio-differential protection,a new debugging method of duplex ratio-differential protection is proposed in this paper.It has been conformed the debugging method is feasible and valid. |
