A large photovoltaic power station using intelligent solar tracking control system enjoys stable operation for years. This article introduced the composition of the sun tracking system, summarized and analyzed its mechanical characteristics, control logic, control mode and other aspects. It is believed that the stable operation of the tracking control system benefits from advanced management concepts, complete hardware systems and safe control logic. Finally, the advantages of tracking photovoltaic power station were analyzed by comparing the power generation of tracking photovoltaic power station and fixed photovoltaic power station. The analysis shows that the intelligent tracking control system adopts the timing interval control mode, and the tracking error is less than 3%; tracking does not depend on external sensors and is not subject to external disturbances; the structure is simple and stable; it doesn’t start motor frequently, reducing the impact of a large number of motor start and stop on the grid.
