从内蒙古乌兰察布地区电网所供负荷来看,60%为高耗能用户,尤其“新城湾、前进变、旗台变、兴广变”用户负荷较大,变电站出线多,所以其安全运行尤为重要。另外,由于负荷增长迅猛,而电网建设相对滞后,“新风变、城东变”用户存在轮流限电问题,在限电时由于用户的频繁操作,启停负荷时对电网的安全运行也有很大影响,从2011年的统计数据来看,全年共发生高耗能跳闸131次,对电网安全运行构成极大威胁。从接入系统的高耗能用户来说,大部分为35千伏
According to the load supplied by the power grid in Wulanchabu, Inner Mongolia, 60% is a high energy consuming user, especially because of “heavy load of Xinchengwan, forward change, Qitai change, Xingguang change” and substation outlet, Its safe operation is especially important. In addition, due to rapid load growth, while the power grid construction lags behind, “new wind changes, Chengdong change ” users turn turns the power limit problem, in the power limit due to frequent user operation, start and stop the load on the grid when the safe operation A great impact, statistics from 2011 point of view, the year a total of high-energy trip occurred a total of 131 times, the safe operation of the power grid pose a great threat. The majority of energy users accessing the system are 35 kV
