摘　　要：为掌握在电力系统中投入使用的燃气发电机组的运行情况,利用Matlab/Simulink仿真软件建立基于GGOV1(General Governor)燃气调速结构和AC8B励磁模型的燃气发电机组的通用动态模型,并以锦州25-1南CEPF海上石油生产平台上现有已投入运行机组的参数作为算例,对燃气轮机(即原动机)、励磁机、主发电机(为励磁同步电机)进行模块化精细模型的建立。通过仿真该机组模型的动态运行情况,机组转速、端电压、励磁电压、原动机输出机械功率、燃气消耗量的变化情况可以被有效监控。仿真结果表明,模型能够较为直观地反映负荷发生动态变化时,机组各物理量之间的联动变化关系,验证了模型的普适性。Aiming to grasp operating performance of gas turbine generator set in power system,this paper proposed a universal dynamic model based on GGOV1(general governor)structure and AC8 B excitation model using Matlab/Simulink.An application example is given with parameters of a gas turbine generator set which is already put into operation on Jinzhou 25-1 southern CEPF offshore platform,and the modular fine model is established for gas turbine(i.e.prime mover),exciter and main generator(i.e.exciter synchronous motor).Through simulation test,rotation speed,terminal voltage,field voltage,output mechanical power of gas turbine,and gas consumption can be monitored effectively.Eventually,the simulation results show that the established model can directly reflect the linkage between the physical quantities of the set when the load changes dynamically,which verifies the universality of the model.
