【Abstract】 The mathematical model of gas turbine generating sets with excitation system and governor system is presented, the simulation model of the excitation system is established in MATLAB and its dynamic performance is analyzed. The User-Defined Model of excitation system and governor system is also established by use of Power System Analysis Software Package (PSASP 6.1). The transient performance and small signal stability of gas turbine generating sets connected to a typical distribution network are calculated and analyzed. The influences of related parameters of excitation system and governor systems on dynamic performance of gas turbine are analyzed, so the foundation is lain for studying the influences of distributed generation on transient performance of power system.更多还原
