  微型燃料电池热电联供系统作为一种清洁的家用发电设备,在供应家庭用电的同时,可以提供家用生活热水,具有很高的综合能源利用效率,因此受到世界各国的高度重视。开展热电联供系统的模型研究,对实际系统的构建具有很好的参考价值。本文在MATLAB/SIMULINK平台上搭建了家用质子交换膜燃料电池热电联供系统(PEMFC-CHP)模型,针对该系统中水冷式燃料电池的散热特性直接受用户侧热水器水温影响的特点,提出了一种基于热水温度的热电联供运行方案。采用该方案,以满足热需求为目标,通过参考模拟的家庭用户一天的用电及用热工况分析了该系统在可变负载下的动态性能,同时计算了系统发电上网的净电量。仿真结果表明,采用该方案不仅可以达到满足居民日常热需求的目标,同时可以满足部分电需求,节省能耗。
