摘　　要：基于Matlab/Simulink平台,根据容积惯性法建立某三轴燃气轮机发电机组非线性动态模型,并定制燃气轮机转速调节及发电机励磁系统控制策略,对动态模型进行阶跃形突增突减负荷变工况仿真研究。结果表明动态模型能够有效地对负荷突变工况进行模拟,为船舶电网供电模块的控制系统设计与优化提供模型基础;在变工况过渡过程中,燃气轮机发电机组动态响应特性满足船舶电网供电品质要求。According to the volume inertia, the nonlinear dynamic model for one type of three-spool gas turbine-generator set was established based on the Matlab/Simulink platform. The control strategy for speed regulation and excitation system was customized.And then the dynamic performance to the stepwise load were studied.The response curves show that the dynamic model accords well to the sudden load change process,and can be used as basal model for the power module control system design and optimization. The dynamic responses of gas turbine generator set meets the requirement of power supply quality for ship grid during the transient process of variable working condition.
