汽轮机运行参数偏差对经济性能影响的分析方法

Analysis Methods of the Economical Performance Change due to the Deviation of the Steam Turbine Operation Parameters

在火电厂性能分析和热力试验中 ,常使用运行参数的修正曲线来修正由于试验时机组各运行参数不在额定值而带来的机组经济性能偏差 ,使实验结果都为额定的运行参数条件下机组的经济性能。利用这种思路 ,介绍了用热力学方法从热力试验数据中拟合得到汽轮机运行参数的修正曲线 ,然后把曲线用于机组实时经济性能偏差分析中的方法。

The operation parameters of turbines are off-designed most of the running time, and the deviation between the real-time data and the rated data makes the deviation of the economical efficiency. This article introduces the method in which the respective deviation resulted from the corresponding operation parameter's deviation can be achieved by using of the fair curve which is fitted with the data in the thermal test of the turbine.
