电动给水泵容量优化对空冷机组节电的影响

The research of how capacity optimization of electrically driven feed pumps influences the power saving of air cooling units

通过对空冷机组运行特性的分析,针对2×300MW亚临界直接空冷机组,建议配置3×50%容量的电动调速给水泵。对电动给水泵的容量进行优化,每台机组建议选配3台50%TRL容量电动调速给水泵,与按规定选配3台50%BMCR容量电动调速给水泵相比,每年大约节电6.54×106kWh,节电效果巨大。

According to the analysis of the operating characteristics of the air-cooling unit,in terms of the engineering construction of 2 ×300MW subcritical direct air-cooling unit,it's better to configure 3 ×50% of the capacity of the electric feed water pump. To optimize the capacity of the pump electric,each unit is proposed to match 3 electric feed water pump of 50% TRL capacity. Compared with optioning 3 electric feed water pump of 50% BMCR capacity in accordance with the provisions,it can reduce the power consumption of 6. 54 × 106 kWh per year. The saving effect is remarkable.
