目前,智能变电站技术的实践主要集中在技术层面上,注重新设备和新标准的应用,而对变电站二次运维研究不深入。针对近两年两起智能变电站运行人员由于不清楚保护装置的投退逻辑,错误的倒闸操作致使相关主变和部分线路跳闸、母线失压的典型事故,通过对事故主因的分析,分析了智能变电站检修二次安全管控管理办法,提出了几点运行维护注意事项,对今后规范智能变电站继电
At present, the practice of intelligent substation technology mainly focuses on the technical level, focusing on the application of new equipment and new standards, while the research on the secondary operation and maintenance of substations is not in-depth. According to the analysis of the main causes of accidents, two intelligent substation operators in the last two years did not know the reason of switching back and forth of the protection device, the wrong switching operation caused the main transformer and some lines to trip and the busbar lost pressure. Intelligent substation maintenance secondary safety management practices, put forward a few points for the operation and maintenance, the future specification smart substation relay
