摘要

基于最优初压理论

建立最优初压计算模型

并以300MW机组为例进行了运行优化试验

按阀点寻优确定曲线上拐点

按初压寻优确定滑压过程的运行初压

并由此得出合理的机组定-滑-定运行曲线。实践表明

机组按此曲线运行经济性较高

参与调峰能力强

安全有保障

且有助于机组节能降耗。

Abstract

On the basis of the optimal initial pressure theory

a calculation model for the optimal pressure was established.Besides

the operation optimization test was conducted on a typical 300MW unit.The curve inflection points were determined by valve point optimization

and the initial pressure during sliding pressure operation was determined by initial pressure optimization.Thus

the reasonable fixed-slide-fixed pressure operation curve for the unit was obtained.Operated according to this curve

the unit had a high economic efficiency and strong ability of participating in peak regulation.This method is helpful to energy saving and safety operation of the unit.
