汽轮机组最佳经济运行方式的确定
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.
