清原县红河电站位于红河干流,于1995年并网发电。该电站总装机为4×1250kW,发电机型号为HL240-WJ-84,可控硅励磁柜型号为FKLI-240/100。年发电量为1000万kW·h。发电机出口电压为6.3kV,经主变升压至66kV后并地区网。地区网负荷主要由红河电站带动。2000年9月20日7:08分地区220kV主变跳闸,因负荷远远大于发电机容量,线路电压由66kV降到54kV时1F、2F发电机跳闸,等地区主变回复后开机时,1F、2F发电机无法起励,经检查2台机的可控硅励磁续流管全部击穿。
Qingyuan County Honghe Power Station is located in the mainstream of the Red River, in 1995 and power generation. The total installed capacity of the plant is 4 × 1250kW, the generator model is HL240-WJ-84, and the SCR excitation cabinet model is FKLI-240/100. The annual generating capacity of 10 million kW · h. Generator outlet voltage of 6.3kV, after the main transformer boost to 66kV and regional network. Regional network load is mainly driven by Honghe Power Station. At 20:08 on September 20, 2000, 220kV main transformer tripping occurred in sub-region. The load is much larger than the generator capacity. When the line voltage is reduced from 66kV to 54kV, the 1F and 2F generators are tripped. , 2F generator can not be inspired by the examination of 2 machine SCR excitation freewheel all breakdown.
