    DESIGN AND IMPLEMENTATION OF PLC-BASED AUTOMATIC SUN TRACKING SYSTEM FOR PARABOLIC TROUGH SOLAR CONCENTRATOR
    Jinping Wang, Jun Zhang, Yanfeng Cui, Xiaolong Bi

    A sun-tracking system for parabolic trough solar concentrators (PTCs) is a control system used to orient the concentrator toward the sun always, so that the maximum energy can be collected. The work presented here is a design and development of PLC based sun tracking control system for PTC. Sun tracking control system consists of a Programmable Logic Controller (PLC) and a single axis hydraulic drives tracking control system. Hydraulic drives and the necessary tracking angle algorithm have been designed and developed to perform the technical tasks. A PLC unit was employed to control and monitor the mechanical movement of the PTC and to collect and store data related to the tracking angle of PTC. It is found that the tracking error of the system is less than 0.6 °. Field experience shows that tracking algorithm act stable and reliable and suit for PTCs.
