摘　　要：船舶主机余热的热电发电系统是一种新型的船舶主机余热发电系统,为了证实热电发电系统用于船舶余热发电的可行性,需要了解系统工作时热电转换的动态过程以及系统对船舶不同工况的适应能力。利用热电转换相关理论,对船舶主机余热的热电发电系统的热电转换过程进行了分析,建立了系统的动态数学模型。并且在系统中增加辅助升压部分,减小了参数波动,提高了系统的稳定性。利用SIMULINK工具对系统进行了仿真,对仿真结果分析表明,上述热电发电系统在船舶不同工况下是稳定可靠的。从而表明利用热电发电技术进行船舶主机余热发电是可行的。The thermoelectric generation system of main engine waste heat is an important auxiliary system in the field of waste heat power generation. In order to confirm the feasibility of the thermoelectric generation system for ship waste heat power generation,the dynamic process of thermoelectric conversion should be analyzed and the adaptability should be tested with different conditions of this system. A dynamic mathematic model was established by analyzing the thermoelectric conversion process using thermoelectric conversion theory. And the parameters fluctuation was considered by adding the auxiliary boost converter part. The analysis of the simulation result on SIMULINK shows that the system is stable and feasible in different work conditions for waste heat power generation.
