Based on the theoretical research for gas turbine speed governors and the experimental research for the practical characteristic of domestic main gas turbine speed governors system,the applicability analysis to existing electric power system simulation software was carried on.Analysis result shows that the existing simulation model cannot reflect the frequency modulation property of domestic main gas turbine.The modeling research for gas turbine speed governors was carried on,and then the simulation model,which is suitable for domestic main gas turbine speed governors,was established.Simulating calculation result and experimental result show that the model can perfectly represent the real frequency-governing properties of gas turbine governors.Along with more and more operation of gas turbines,using this model to carry on the simulation computation for electrical power system can simulate the real dynamic property of the electrical power system.It is of great significance to solve the problems of domestic electrical power system safety.
