摘要
随着社会用电量不断提高,变电站长期处于高负荷运行状态,发生故障的可能性较高,为提升变电站运行稳定性,引入二次继电保护技术至关重要.文章分析智能变电站特点,基于智能化变电站运维需要,明确二次继电保护技术应用准则,从明确保护要求、优化设计、引入智能监控设备、智能整定与在线校核、自适应继电保护及智能告警等方面,提出应用二次继电保护技术的策略,降低变电站运行期间出现故障的可能性,为技术应用提供参考.
Abstract
With the continuous increase in social electricity consumption,substations are operating at high loads for a long time,and the possibility of faults is high.To improve the stability of substation operation,it is crucial to introduce secondary electromechanical protection technology.The article analyzes the characteristics of intelligent substations,and based on the needs of intelligent substation operation and maintenance,clarifies the application criteria of secondary relay protection technology.From clarifying protection requirements,optimizing design,introducing intelligent monitoring equipment,intelligent setting and online verification,adaptive relay protection and intelligent alarm,etc.,it proposes strategies for applying secondary relay protection technology to reduce the possibility of faults during substation operation,providing reference for technical application.
