摘要
首先介绍了AVC系统控制原理;接着针对万州电网AVC系统遥控成功率低的问题,结合具体变电站设备遥控失败的现象(如遥控返校错误、未收到变位动作、遥控执行失败等),以分析报文为手段,讨论失败的原因;最后提出解决方法,并将其方法用于其他厂站设备研究,大大提高万州电网AVC系统遥控成功率。
Firstly, the control theory of automatic voltage control （ AVC） system is introduced .Then aiming at the low success rate of remote control in AVC system , the reasons are discussed by means of message analysis considering the remote control failures of substation equipment .At last, the solutions are put forward and applied to the equipment research in other power plants and substations , which greatly improves the success rate of remote control for AVC system in Wanzhu power grid .
