Abstract

This paper studies the mathematical simulation model based on the F class gas steam combined cycle unit, which provides a basis for the off design performance calculation of gas turbine and combined cycle, and meets the major technical requirements of the overall design of the unit. As the main basis for the overall design of gas turbine and combined cycle, the performance analysis results play an important supporting role. Therefore, the modeling and simulation method of gas turbine and combined cycle is a key supporting technology in the design process of heavy gas turbine and combined cycle, and the accuracy of the model has an important impact on the design results. Whether the accuracy of gas turbine and combined cycle simulation model can meet the design requirements is directly related to whether the design can be effectively carried out.
