0.4kV可控硅动态无功补偿装置的应用

Application of 0.4 kV thyristor dynamic reactive power compensation device

在电力系统运行中,为减少能量损耗,提高供电设备利用率,需要采用无功功率补偿。介绍江苏金坛地区在中频炉、电弧炉客户中,电焊企业、商业、居民用户试用SVC可控硅动态无功补偿装置,构成低压动态无功补偿,提高功率因数,降低线路损耗,提高电能质量,节电效果明显。

In power system operation, in order to reduce en- ergy loss and improve the utilization rate of power supply equipmeat, reactive power compensation is needed. In this paper, intermediate frequency furnace, electric arc furnace customers, welding business, commercial, residential users in jintan region try to use dynamic reactive power compensation devices, consti- tute a low-voltage dynamic reactive power compensation to improve the power factor, reduce line losses, improve power quality. The energy-saving effect is obvious.
