Basic control engineering of a DSG solar field

Control architecture for the whole 5MWe DSG power plant were defined. Control room at the main building, control units for the main systems and communications infrastructure.

Regarding the solar field, Local Control Units, which communicate, with the DCS were fully integrated in the control engineering design of the power plant. Such LOC's, which have already been designed, tested and validated at the PSA, operate in open loop arrangement. They calculate the position of the sun via astronomic algorithm, check the current position of the parabolic trough collector via lineal encoder mounted in the axis of the structure and command the hydraulic drive units located at every drive pylon.
