【摘要】：智能变电站技术的推广为继电保护的运维提供了新的思路和技术手段。基于状态信息的在线监测将有利于提高智能变电站继电保护系统的可靠性,减少运维的工作量。从智能变电站继电保护组成的角度出发梳理了继电保护的状态信息,分析了状态信息之间的关联关系,通过对继电保护实时采集和上传的状态信息增加逻辑运算和判断比较,提出了基于状态信息各种关联关系的继电保护在线监测方法。算例表明本文方法能够发现继电保护的某些异常,从而提高智能变电站继电保护运维的有效性。
[Abstract]:The popularization of intelligent substation technology provides new ideas and technical means for relay protection operation and maintenance. On-line monitoring based on state information will help to improve the reliability of intelligent substation relay protection system and reduce the workload of operation and maintenance. From the viewpoint of the composition of relay protection in intelligent substation, the state information of relay protection is combed out, and the relationship between state information is analyzed. The logic operation and judgement comparison are added to the state information collected and uploaded in real time for relay protection. An online monitoring method for relay protection based on various correlation relationships of state information is proposed. Numerical examples show that the proposed method can detect some anomalies of relay protection and improve the effectiveness of operation and maintenance of relay protection in intelligent substation.
