摘　　要：对微型燃气轮机发电系统启动与发电过程中的控制策略及启发一体过程进行研究。启动过程中,利用网侧变流器的整流稳定作用,使电网的交流电转化为直流电,利用机侧变流器将直流电逆变为高频交流电,驱动电机提升转速,当实时转速达到额定转速后,完成微型燃气轮机的启动。发电过程中,永磁同步电机转动产生高频交流电,利用机侧变流器,将交流电整流成为直流电,并维持母线电压稳定。利用Matlab软件,构建启动/发电一体运行模型并进行启发切换的仿真验证,结果表明,该模型可在启动状态与发电状态之间做到平滑切换,达到了设计预期。The control strategy and heuristic integrated process of micro-gas turbine power generation system in the start-up and power generation process are analyzed.In the start-up process,the grid side converter is used to convert the alternating current of the power grid into direct current,and then the machine-side converter is used to convert the direct current into high-frequency alternating current to drive the motor to increase the speed.When the real-time speed reaches the rated speed,the start-up of the micro gas turbine is completed.In the process of power generation,the permanent magnet synchronous motor rotates to generate high frequency alternating current,which is rectified into direct current by the machine side converter,and maintains the voltage stability of the bus.Matlab software is used to build the start-up/power generation integrated operation model,and the simulation verification of inspiration switching is carried out.The results show that the model can smoothly switch between the start-up state and the power generation state,reaching the design expectation.
