Research on Modeling and Simulation for On-line Status of Gas Turbine

Condition monitoring plays a significant role in the operation security of gas turbine.In order to optimize online monitoring and performance evaluation of gas turbine,so as to provide means for diagnostics of thermal performance and trends prediction of the components,the paper completed system modeling based on working characteristics of single-shaft gas turbine,and determined the operating point of various components with Newton iteration.Through the computational model for condition monitoring,software was developed for performance evaluation.Result from the model has the same tendency as the operation data.The model meets the needs of online condition monitoring for gas turbine,and can be put into engineering applications.
