Research on Simulation Method of Starting Process Based on Up-and-down Rate under Quasi-steady Assumption
In order to exactly perform the performance simulation of highly non-linear gas turbine starting process under quasi-steady assumption,by the method of given acceleration rate,the right side of the starting equation was linearized,realizing the quasi-steady-state simulation of the starting process.The design flow of starting simulation using this method was given,and the simulation and optimization analy-ses of different compressor angle adjustment rules and different starter power were carried out.The com-parative analysis between the simulation results and the test data shows that the main parameters,such as the speed up,rotating speed,working line and starting time,are in good agreement with the test data,and the variation trend of the performance and cross-section parameters of the gas turbine conforms to the engineering practice.
