Solar-coal Complementary Electric Generation System and Its Modes

Utilizing multi energy sources synthetically and efficiently based on the system integration is one of the trends of energy science recently. Researches on solar-coal complementary electric generation system and its modes were performed. Firstly, thermal economy was analyzed when solar energy was used at different surface or heaters in various capacity coal-fired units. It is concluded that using solar energy to evaporate water in large capacity units is better than others; Thermal system was then proposed when the mature parabolic trough collectors were used to collect solar heat and integrated into a native 300 MW coal-fired unit. Finally, the factors affecting the chosen of designed solar irradiance were also discussed during the designing process of solar fields in a hybrid generation unit. In addition, solar resources of three different sites were used as examples to calculate the optimum designed solar irradiance, and the relationship between solar resources and the optimum designed solar irradiance was obtained.
