technical field [0001] The invention mainly relates to the technical field related to Stirling thermal power generation, in particular to a concrete heat storage disc solar Stirling thermal power generation system. Background technique [0002] The Stirling thermal power generation system that uses the solar energy concentrated by the dish concentrator as the heat source is called the dish Stirling thermal power generation system. Although dish solar thermal power generation technology is one of the highest photoelectric conversion efficiency methods in solar thermal power generation, there are few studies on heat storage systems. Dish-type solar thermal power generation consists of concentrators, receivers, heat engines, brackets, tracking control systems, etc. During operation, the dish-type concentrator of the rotating parabola is used to focus the sunlight on the receiver installed at the focus of the parabola.

Problems solved by technology

[0003] There are still some problems in the existing solar Stirling power generation system: (1) The heat storage cost of most solar Stirling thermal power generation systems is relatively high, which is not conducive to large-scale promotion

(2) The intelligent control function of the current heat storage system is insufficient

(3) At present, most of the researches on Stirling access heat are carried out inside Stirling, and there is a problem of insufficient internal space for small and medium-sized Stirlings
