摘　　要：以综合电力系统的电源模块为研究对象,采用Matlab/Simulink仿真软件,基于燃气轮机各部件的电气特性,建立某单轴燃气轮机发电机组控制系统仿真模型,对其进行分级加、减载及三相短路故障仿真实验,研究在燃气轮机转速和同步发电机励磁控制系统协调作用下机组的动态特性。结果表明在负荷波动过程中,控制系统协调作用能够确保发电机组调速及调压性能满足电网要求,使得供电品质达到电网指标。Taking the power module of integrated electric power system as the object of the research,based on electrical characteristics of gas turbine components,this paper establish the control system model of single-shaft gas turbine generator set using the Matlab/Simulink software,and carry out variable load and three phase short circuit fault experiment to study the dynamic performance of generator set under the coordinated control of gas turbine speed and synchronous generator excitation. The results show that the speed control performance and voltage adjustment performance of generator set could meet the requirements of power grid in the process of load fluctuations. which made the power supply quality reach power grid indicators.
