摘　　要：半物理仿真是仿真领域研究的热点和难点,在研究系统性能和控制策略时非常有用。结合燃料电池燃气轮机联合循环的特点,提出了上位机、下位机+实物部件的形式组成联合循环半物理仿真系统,基于PLC(Programmable Logic Controller)开发了此系统的下位机程序,实现了数据采集、与上位机通讯、系统参数控制以及对跳变时温度的特殊控制等功能,并且介绍了程序实现的主要代码。试验表明,该系统的下位机程序具有很好的实时性、精确性和稳定性。The hardware-in-loop simulation is hotspot and difficulty in the simulation field and very useful in studying the characteristic and control strategy of a system. According to the feature of fuel cell-gas turbine combined cycle system, the hardware-in-loop simulation system of combined cycle is brought forward which is composed of host computer、client computer and correlative hardware. The software portion of the client computer has been developed based on PLC. The functions of sampling data, communicating ...
