摘　　要：通过对火力发电厂循环冷却水系统进行的理论和试验研究,综合得出不同冷却水温和不同机组负荷下保持机组处于最经济运行真空的理论依据,实现了将循环水系统的优化调节设想转化为可行的工程指导,解决了长期以来困扰电厂实现循环水系统优化运行的难题。Through the theoretical and experimental study on circulating cooling water system for power plant, the the- oretical support for keeping the unit in the most economic condenser vacuum under different cooling water tempera- tures and differnt unit loads was obtained. The idea of optimal control of circulating water system was able to be transformed into practicable engineering guidance and the problem in optimal operation of the circulating water system which has puzzled power plants for a long time was settled.
