Research on Model Updating of Marine Gas Turbine Based on Optimization Algorithm
Gas turbine has been widely used as a marine power plant.In the development process of gas tur-bine,it is very important to establish a high-precision mathematical model that can reflect the actual performance of gas turbine.In order to improve the accuracy of gas turbine simulation model and play a better role in perform-ance analysis and prediction,a method for updating the steady-state simulation model of marine gas turbine based on optimization algorithm is proposed.Combined with the measured parameters in the gas turbine test process,the characteristics of gas turbine components and related parameters can be modified,so as to obtain an accurate mathematical model of gas turbine.This method has been applied in the test of a gas turbine.Compared with the original model,the accuracy of the main parameters such as power,fuel flow and exhaust temperature has been greatly improved,and the trend is more consistent with the reality,and the practical application effect in engi-neering is good.
