Description

Technical field: [0001] The title of the present invention is a dish type solar thermal power direct conversion system, which belongs to the field of energy power engineering. Background technique: [0002] Static power generation is a production process that directly converts thermal energy into electrical energy. Compared with traditional dynamic power generation, that is, heat energy is first converted into mechanical energy and then converted into electrical energy. Static power generation reduces the energy conversion links in the entire production process, and the energy loss is corresponding Reduced, so that the operating cost and instability of the entire system will also be greatly reduced. From this point of view, static power generation may provide better economy and stability than dynamic power generation. Therefore, some scholars have proposed to use a thermoelectric direct converter with no moving parts, no noise, and no maintenance to generate power, that is,...
