摘　　要：为证实热电温差电池作为储备新能源应用到船舶电网中的可行性,需了解热电温差电池并网发电时的工作特性、装机容量和效能。利用热电转换相关理论精确描述热电温差电池的输出特性,建立完备的功率传输模型和效率模型。为实现效能最大化,设计热电温差电池的分布式结构,采用最大功率点跟踪技术和分布式开关控制技术,提高热电温差电池的输出功率,增强系统的稳定性。利用Simulink工具对系统进行仿真,仿真结果表明,采用最大功率点跟踪技术和分布式开关控制技术实现分布式热电温差电池的并网发电是可行的。In order to examine the feasibility of thermoelectric battery for ship power as a new energy storage alternative, it needs to understand the dynamic characteristics of thermoelectric power generation and the possible capacity and efficiency of battery of this kind. A complete power transmission/efficiency model is established through analyzing the thermoelectric conversion process using thermoelectric conversion theory. In order to achieve the performance requirements of the ship sys- tem, the distribution topology of batteries and the combination of Maximum Power Point Tracking （MPPT） and distributed switch control is introduced to improve the output power and enhance the stability of the system. The simulation of a ship waste heat recovery power generation system with distributed thermoelectric batteries is carried out and the results show that the large capacity thermoelectric battery with MPPT and distributed switching control is feasible.
