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.
