摘要
随着地区经济的快速发展,地区局部电网重载情况越来越突出,成为影响电网安全稳定运行的一大隐患,秦皇岛西南部电网的龙小双回线路,线径较小,供电压力沉重,武山站、龙家店站长期处于重载情况下运行。若龙小一回线发生故障,必须采取措施快速控制西南部地区负荷,确保运行线路不发生相继故障。据此,秦皇岛地区在西南部电网安装了过负荷联切装置。此稳控装置可以在线路发生N-1故障时快速切除负荷,有效缩短事故处理时间,提高了地区电网运行的安全性。
With the regional economic development, southwest of Qinhuangdao grid has heavy pres- sure on power supply. Wushan----Longjiadian transformer stations is a long running case of heavy load. In order to ensure that the operation does not occur in succession fault line. Consider the transmission path of the operating conditions and load capacity of the line, if a small one long loop fails, it must take mea- sures to control the Southwest load fast. Accordingly, Qinhuangdao grid installed in the southwestern se- curity control equipment. The security control unit can occur in the line N--1 fault rapid removal of the load. This device can effectively reduce incident handling time and improve the regional power grid opera- tion security.
