标积制动式纵差保护的整定问题

Setting Problem for Scalar Product Differential Protection

标积制动式纵差保护的原理独立于比率制动式纵差保护。前者的制动系数Ｋ′ｒｅｓ既不适宜也不必要从后者的制动系数Ｋｒｅｓ中推算出来。文中引用了三峡水轮发电机的计算实例。

The principle of scalar product differential protection is independent of percentage differential protection.The restraining coefficient of the former is inappropriate and unnecessary to calculate from the latter.In this article an example of Three Gorges hydraulic generator is quoted.
