摘　　要：研究了一种利用AspenPlus软件模拟固体氧化物燃料电池热电联供(SOFC-CHP)系统的方法,并以1 kW级系统为例进行了计算,该方法可用于快速判断不同燃料及电堆功率要求下的SOFC-CHP系统热电供应情况。试验结果表明,在理想状态下SOFC的净发电效率可达51%,热效率高达42%,CO_(2)排放摩尔分数高达70%。所提方法可极大缩短计算速度,对进一步优化系统效率很有帮助。The software Aspen Plus is taken to simulate a combined heating and power system integrated with solid oxide fuel cells(SOFC-CHP).Taking a 1 kW SOFC-CHP system as an example,the simulation method can make quick judgement on the heat and power supply situations of the system with different fuels and under various load requirements.The test results show that in the ideal condition,the power generation efficiency of the SOFC can reach 51%,the thermal efficiency can peak at 42%,and the emitted CO_(2) mole fraction can be 70%.This method can greatly shorten the calculation time and facilitate the efficiency improvement of the system.
