摘要

单轴燃气-蒸汽联合循环(单轴联合循环)机组蒸汽与燃气功率(蒸燃功)比是整个机组性能计算的重要参数

但无法直接测量得到。以质量能量平衡为基础

建立了燃气轮机输出功率、蒸燃功比等参数的计算模型。基于一体化过程模型开发平台

开发了单轴联合循环机组在线性能计算软件

并在某电厂STAG 109FA联合循环机组SIS中进行了应用。结果表明

使用该计算软件计算数据可靠

可满足实际需要。

Abstract

The steam-gas power ratio of a single-shaft gas-steam combined cycle unit is an important parameter for performance calculation of the entire unit

and it can't be obtained directly from measurement.A model for calculating the parameters of the gas turbine's output capacity

and steam-gas power ratio etc.has been established on the basis of mass-energy balance principleo.The on-line performance calculation software for the unit has been developed on the basis of integrated process modelling platform

and the said software being used into the SIS of a STAG 109FA combined cycle unit in one power plant.Results show that the application of said calculation software can obtain reliable calculated data

satisfying the requirements in practical application.
