摘要：To further improve the traditional coal-fired power generation, lower the pollutant emission, and comprehensively implement the energy saving and emission reduction policy, the view that the solar-assisted coal-fired power generation system is the complementary and integrated power system of clean energy and traditional fossil energy has been put forward in the paper. Due to the complexity of solar-assisted coal-fired power generation system, the unified integration principles of the system haven’t been established yet. On the basis of the energy conversion happened in the solar-assisted coal-fired power generation system and the simple coal-fired power generation system, a physical model of two different power input of the power generation system is established, the instantaneous photoelectric efficiency expression of solar-assisted coal-fired power generation system is obtained, and the major factors that affect the solar-assisted coal-fired power generation system are concluded. The results provide the practical in-progress solar-assisted coal-fired power generation system with a basic theoretical basis. Therefore, on the one hand, the solar-assisted coal-fired power generation system helps the large-scale and low-cost development and exploitation of solar thermal power systems; on the other hand, it accelerates the implementation of energy saving and emission reduction policy in traditional coal-fired power plants. It is an effective solution to the problems of ever-increasing environmental pollutions and the limited traditional fossil energy supplies.
