The molten salt storage tank 2 is used for storing solar radiation energy absorbed in the daytime in a heat energy mode, and releasing the solar radiation energy to perform thermal power generation when the sunlight is insufficient at night or in cloudy days, so that the power station can generate power continuously and stably. The system of the invention selects the heat storage medium as the molten salt, and has the advantages of low price, high working temperature, stable property and the like.
As shown in fig. 2, under the driving of the molten salt pump 7, the molten salt continuously performs a cooling and heating cycle among the light condensing device 1, the molten salt storage tank 2 and the hydrogen source heat engine generator 3, and the solar energy collected by the light condensing device 1 is transmitted to the hydrogen source heat engine generator through the molten salt, and is converted into electric energy and heat energy to be output externally.
