摘　　要：电力系统继电保护的主要任务是反应一次设备的工作状态,控制和调节一次设备。随着电网结构越来越复杂,继电保护定值的整定工作量日益增加,这必然导致保护定值间的配合日趋困难。就此问题,提出了解决方案并对继电保护在线校核软件的结构和功能进行了探讨,对其中关键问题进行了研究。The main objectives of any relay protection schemes in power system are to response the working state of primary equipment and to monitor and control them. Nowadays,with more and more sophisticated structure of power grid,the adjustment of relay protection setting values increases gradually,which inevitably leads to the hard coordination among the protection setting values. As the result,some solutions are proposed,the structure and function of on-line checking software for relay protection are discussed,and the key problems and technical difficulties are investigated.
