| description | A novel parabolic sun-tracking system is proposed, in response to inefficiency of solar energy utilization due to the low tracking accuracy of sun-tracking system for parabolic trough solar concentrator. The mathematical model of trough photothermal single-axis tracking is established based on solar position algorithm (SPA) and the influence of different arrangements on the operation characteristics of the system is studied. The prototype test system is built and the tracking control logic is developed based on programmable logic controller (PLC). The application of high-precision algorithms in the PLC controller is realized through custom embedded programming. A strategy of intermittent control based on deviation of tracking angle is proposed. The push-pull drive mechanism with dual hydraulic cylinder and medium and high pressure is utilized to drive the trough concentrator with the purpose of real-time tracking of the solar position. The hardware and software architecture, main function modules and control flow of PLC control system are expounded. Besides, redundancy configuration of the controller and monitoring network are adopted. Operating data shows that the system has features of simple system structure, convenient maintenance and high tracking accuracy. |
