With the China high-speed railway promoting social and economic improvement, developing clean and renewable energy as EMU' s supplementary or alternative sources of energy has importantly practical significance. The feasibility of applying solar PV technology on EMU is discussed, and the simulation output characteristics of EMU PV system under various operating conditions are studied, the method of maximum power point tracking of PV system on EMU is carried out and simulated.%中国高速铁路在推动社会和经济快速发展的同时也消耗了大量能源,因此开发清洁可再生新能源作为动车组补充或替代能源具有重要的现实意义.文章探讨了在动车组上利用光伏发电技术开发太阳能资源的可行性,对动车组光伏发电系统在多种工况下的输出特性进行仿真研究,提出并仿真研究了在动车组上实现光伏系统最大功率跟踪的方法.
