摘要

针对现有基于保护范围校核计算方法的不足，对比分析了保护整定与校核的区别和联系，得出校核是整定逆过程的结论。在此基础上，结合整定计算思路，提出了基于整定逆过程的保护定值在线校核思想，并以距离保护为例，给出了普遍适用的校核计算原则及公式，并对其中的特殊问题进行了相应的处理。该方法与整定计算风格形式一致，易于用户迅速从整定计算过渡到校核计算。工程算例验证了该方法的正确性和可行性。

Abstract

In view of the current inadequate method of protection range verification， and from a comparative analysis of the differences and relations between protection setting and verification， it is concluded that verification is the inverse process of protection setting. On this basis and taking into consideration the idea of protection setting calculation， an on-line verification method based on the inverse process of protection setting is presented and the universal formulae and principles of on-line verification on distance protection are given. Furthermore， some specific problems are given corresponding treatment. The style of the method presented is consistent with the protection setting calculation， making it easy for users to quickly divert from setting calculation to verification calculation. The correctness and feasibility of this method is verified by practical examples.
