The use of solar energy at oil and gas complex facilities is a promising direction for the development of alternative energy. Hydraulically driven trackers are capable of ensuring stable and reliable operation of energy facilities. The efficiency of a solar tracker directly depends on the reliability and operational capacity of the hydraulic system that controls its movement. The article presents the analysis of the existing hydraulic systems in relation to solar trackers. The modeling of the process of adjusting a solar tracker with a hydraulic drive intended for oil and gas production facilities is considered. A basic hydraulic diagram of the hydraulic drive is presented. The stability of pistons movement of two hydraulic cylinders of the tracker is studied taking into account the wind load. The efficiency of the system with LS-regulation and its stability under variable load conditions have been confirmed, thus making this approach promising for reliable energy supply to oil and gas facilities.
