摘　　要：介绍燃气发电机组功率调节的主要方式、传统发动机控制器的特点,以及通用型PLC在较复杂控制系统中的优势。对发动机输出功率、转速、转矩之间的关系进行分析,得出通过控制发动机节气门开度调节燃气发电机组输出功率的控制策略。通过建立节气门数学模型并仿真,对发电机组输出功率的控制进行理论研究。在一台微型燃气热电联产机组上进行试验,验证了负功率控制、功率平滑控制和带死区控制等算法的可行性和优势。The main ways of power regulation of gas generator set is introduced,the characteristics of traditional engine controller,and the advantages of general PLC in complex control system.The relationship among engine output power,speed and torque is nalyzed,and the control strategy of adjusting the output power of gas generator set by controlling the throttle opening of engine is obtained.Through the establishment of throttle mathematical model and simulation,the output power control of generator set is studied theoretically.The feasibility and advantages of negative power control,power smoothing control and dead zone control are verified by experiments on a micro gas cogeneration unit.
