摘　　要：结合质子交换膜燃料电池(proton exchange membrane fuel cell,PEMFC)电化学特性、气体流量特性及温度特性,考虑FC模块的效率及寿命,建立基于PSCAD/EMTDC的PEMFC发电系统自定义动态模型,提出PEMFC组中FC模块运行优化算法及其并网控制策略。FC模块运行优化利用先进先出算法,实现FC模块等时运行,DC/DC变换部分采用Boost电路电压外环、电流内环的双环控制,实现DC电压平稳输出,DC/AC并网逆变器采用功率外环、电流内环的双环控制的定功率控制策略,实现系统友好同步并网。通过PSCAD/EMTDC软件平台,仿真验证了所提系统的正确性和有效性。According to the electrochemical, gas flow and temperature characteristics of proton exchange membrane fuel cell （PEMFC）, a custom dynamic model of the PEMFC generation system is established based on PSCAD/EMTDC with consideration of the FC module efficiency and life span, and the PEMFC operation optimization algorithm and grid-connection control strategy are proposed. The FIFO algorithm is adopted in FC module operation optimization, and the equivalent FC module running time is achieved. Boost circuit and double loop control of outer voltage loop and inner current loop are adopted in DC/DC conversion section, and steady output of voltage is achieved. Constant power control strategy of double loop control of outer power loop and inner current loop is adopted in DC/AC grid-connected inverter section, and friendly and synchronous grid-connection of PEMFC grid-connected power generation system is achieved. The correctness and effectiveness of the proposed system in this paper are verified through the PSCAD/EMTDC software platform.
