我省庙宫水电站,装机容量3×500千瓦,水轮机型号HL123-WJ—59,发电机型号为TSWN99/46—8,配用XT—600型调速器。1985年7月2日,因线路故障突甩负荷,1~#、3~#发电机被烧毁。此次事故除生产管理等方面原因外,也反映出整流操作接线上的一些问题,值得探讨。一、庙宫水电站直流系统接线庙宫水电站直流系统为硅整流电容储能装置。电源引自发电机母线及10千伏线路备用厂用变压器,通过两组整流器在直流侧并联,储能电容分为两组,一组供发电机及主变、另一组供线路后备保护电源。设计储能
Miaomi hydropower station in our province, installed capacity of 3 × 500 kilowatts, turbine model HL123-WJ-59, generator model TSWN99 / 46-8, equipped with XT-600 governor. July 2, 1985, sudden load rejection due to line failure, 1 ~ #, 3 ~ # generator was destroyed. The accident in addition to production management and other reasons, but also reflects the rectifier operation of some of the problems, it is worth exploring. First, Temple Temple hydropower station DC system wiring Temple Temple Hydropower Station DC system for silicon rectifier capacitor energy storage device. Power from the generator bus and 10 kV line backup plant transformers, rectifier in the DC side by two sets of parallel, storage capacitor is divided into two groups, one for the generator and the main transformer, and the other for the line backup power protection .
