大型发电厂启备变带公用负荷接线方式改造经济性探讨

Discussion onReforming Economy ofImprovement of Wiring of Start-up and Standby Transformerwith Public Load in Large-scale Power Plant

网厂分家后,电厂启备变用电按大工业用户用电进行收费。为提高电厂经济效益,对用电系统进行调整和改造,启备变带公用负荷接线方式厂用电深度进行优化,启备变改热备用方式。综合改造费用、改造前后厂用电量及费用,启备变改热备用方式运行后,厂用电量降低35%以上,整体节约费用近200万元,经济性显著。

After the grid and the power plant are separated,the power consumption of start-up and standby transformerwas charged by large industrial users.In order to improve the economic efficiency of power plants,the electricity system was adjusted and improved.The wiring of start-up and standby transformer with public load was optimized.The hot standby mode was used.Integrated renovation costs,plant electricity consumption and costs before and after renovation,after the start-up standby transformer turn into hot standby,plant power consumption reduced more than 35%and the overall cost savings of nearly 2 million.The economy was significant.
