| Micro gas turbine power generation system(MTGS)is a multivariable,nonlinear complex system.Because of its rapid development of power generation technology,it has been continuously improved,and has become an important part of distributed power supply.In this paper,the dynamic characteristics of micro turbine power generation system based on the simulation platform is established with complete mathematical model of micro gas turbine and power generation system,grid load running,the speed module by adding a variable universe fuzzy PID control,simulation analysis of the control strategy has good stability and robustness.In the operation of micro gas turbine power,instantaneous power theory and the principle of hysteresis current control based on the design of constant power inverter main circuit and control circuit principle diagram and PQ diagram of constant control strategy,micro gas turbine hysteresis built in Matlab/simulink constant power decoupling control of PQ simulation model,the simulation results show that the control method has a good dynamic and static performance,the inverter output voltage,frequency,phase and three-phase current total harmonic distortion rate conforms to the national requirements of the grid. |
