【摘要】 热电联供系统为复杂的非线性系统,时间尺度跨度大,热力系统、电力系统的响应特性存在较大差异,系统仿真效率和准确度难以兼顾。针对上述问题,提出了一种基于Simulink/SimPowerSystems的固体氧化物燃料电池热电联供系统多速率仿真方法。采用MatlabS函数建立了固体氧化物燃料电池动态模型,基于电路类比法建立了热力管网等效电路模型。根据不同系统和设备的响应特性进行分区仿真,不同分区使用不同的仿真步长。最终,通过算例分析,验证了所提出多速率仿真方法的有效性。更多还原

【Abstract】 The CHP system is a complex nonlinear system. It is difficult to balance the efficiency and accuracy, due to the CHP system has a large time scale span and the response characteristics of the thermal system and the electrical system are quite different. To solve this problem, a multi-rate dynamic simulation method for the CHP system based on SOFCs using Simulink/SimPowerSystems is proposed.The model of SOFC is established using Matlab S-function. The equivalent circuit model of thermal network is established. Perform partition simulation based on the response characteristics of different systems and equipment in the CHP system. Different partitions use different simulation steps. Finally, the effectiveness of the proposed multi-rate simulation method is verified.更多还原
