摘要
交流站用电系统是一个变电站的重要组成部分,交流站用电系统运行的可靠性直接影响电力一次系统的安全运行。介绍了一起由于站用电系统上下级开关保护等配合不当引起的交流站用电全失事故。同时通过事故模拟试验对事故原因进行了分析,并提出了防范对策。
AC station service power system is an important part of the transformer substation. Whether it operates reliably or not directly affects the safe operation of the power primary system. This paper introduces an accident of AC power losing which caused by the inconsequent protective cooperating of station power system switches. Meanwhile, the causes of the accident are analyzed by simulant experience and precautions are proposed.
