The dish concentrating solar technology has attracted more attention due to its high light-comprehensive axis tracking is taken as the object, whose tracking control and energy conversion characteristics are studied in-depth. Specifically, the dish-type concentrator photovoltaic system is described in detail from the following three parts: concentrating power generation system, tracking control system, and cooling system. As the main control model, an independently designed closed-loop tracking control system is used based on PLC, which operating every 60 seconds with the tracking accuracy under 1%. In order to demonstrate the tracking accuracy of the system, some experiments are carried out on this platform, including measuring the outer wall temperature of the secondary reflection unit by thermocouples and recording the temperature distribution of the focus spot by infrared camera. Finally, thermal dynamic analysis is carried out to evaluate the overall performance and energyflow characteristics of the photovoltaic system.
