摘　　要：总结了河北南网数年来重视继电保护正确动作后的延伸分析,并指出其是较好地保障电网安全稳定运行的一种做法。提出“故障”是一笔日益减少的稀缺“资源”,充分利用故障资源,检验分析继电保护可能存在的隐患,及时采取有效措施解决发现的问题,将对保障电网的安全稳定运行发挥积极的作用。Extended analysis to ensure the security and stability of South Hebei Power Network is summarized through years of experience. The idea is to emphasize the extended analysis on correct operations of protective relay besides incorrect ones. It is a effective way to make full use of the fault resource, analyze thoroughly the possible hidden trouble of protective relay, and finally take measures to solve the problems. All these efforts will play a positive role on the safety and stability operation of power grids.
