摘要：AbstractConsidering the requirements of economy, emission and dynamic performance of three-shaft gas turbine for sudden unloading, the multi-objective optimization of three-shaft gas turbine performance was carried out. Firstly, the simulation model of three-shaft gas turbine was established, and the accuracy of the model was verified by comparing with the design point parameters. Then, the research of multi-objective optimization of the economy, emission and dynamic performance for sudden unloading is carried out based on the three-shaft gas turbine model, and the TOPSIS method was used to select the optimal point in the Pareto solution set. This paper provides a theoretical basis for the performance improvement and optimization design of the three-shaft gas turbine.
