【 摘 要 】

With the increasing pressure of energy shortage and the environment pollution, it's important to take the advantage of the renewable clean energy for newpower generation technology. Solar energy, as a kind of energy with a wide range of sources, has become a new type of clean energy with the most potential for development. This study introduces the project test and progress of solar gas turbine combined generation technology at home and abroad as well as the research status of key technologies. The key technologies of heat collection, heat storage and heat recovery are analyzed and summarized, it has been pointed out that the concentrator ratio achieved by the dish and tower is more than an order of magnitude higher than that of the linear Fresnel and slot Thermochemical heat storage technology has the theoretical maximum energy storage density, the heat storage of chemical bonds is about 5 times of latent heat, 10 times of sensible heat, and has the advantages of stable chemical bonds, small energy loss and other advantages, energy storage in the future has more development advantages. At the same time, the future research direction of solar thermal power generation technology is prospected.
