摘要
双速循环水泵在电厂冷却系统中使用较多。随着高电压、大容量变频器技术的发展以及产品价格的下降,变频器作为调速节能的重要手段之一,已经在火电厂开始应用。本文对A电厂2×350MW间冷空冷供热机组采用双速和变频循环水泵方案进行优化、比较研究。
The two-speed circulating pump is widely applied in power plant. With development Of the high-voltage, large capacity inverter technology, price of fi＇equency converter is declined sharply. Frequency conversion technology is applied in power plant more and more as one of the important means of energy saving by speed regulation. In this paper, a comparative study of two-speed and variable frequency circulating pump programs applied in an air cooling cogeneration powor plant （2×350MW） is done.
