摘要
对于循环水流量不可连续调节的循环水系统,通过对循环水管网水力工况分析以及凝汽器传热特性计算,利用离散优化模型对循环水系统进行了优化运行研究,得出机组不同负荷、不同循环水进水温度下最经济的循环水泵编组运行方式。将优化结果编制成循环水系统离散优化图,以供运行调节参照。
For the circulating water system with flow rate of the circulating water can not be continuously adjusted, through analysis of hydraulic performance in the circulating water pipe network and calculation of heat transfer property in the condenser,a study on operation optimization of the said circulating water system has been carried out by using the discrete optimization model,obtaining the most economic operation mode of circulating water pumps in grouping under different loads of the unit and under different temperatures of the inlet circulating water. A discrete optimization diagram of the circulating water system has been worked out from the optimized results, providing with reference for adjustment in operation.
