Relevance. The operation of the electric drive of deep-well sucker rod pumping units is characterized by a periodic nature of load changes, which, within a group of independent electric drives of a well cluster, can cause significant power fluctuations in the supply network. To reduce peak loads in the network, which are random in such systems, it is proposed to organize synchronized control of pumping units at a cluster of wells equipped with an adjustable electric drive of a sucker pump unit. The paper considered several approaches to developing energy-efficient control algorithms, as well as conducting pilot tests of electric drives of technological machines and mechanisms, which include a sucker rod pumping unit, such as computer modeling, modeling of system dynamics using HIL and PHIL simulators and other methods. At the final stage of testing the control system in the presented work, an electromechanical test bench was used, which made it possible to test the proposed control algorithm in laboratory conditions. Aim. Synthesis of an energy-efficient control system for a group of electric drives of sucker-rod pumping units, ensuring a reduction in fluctuations in power consumption in the electrical network under periodically changing loads. Methods. Mathematical and computer modeling in real time, physical modeling based on a test bench. Results and conclusions. Improving the quality of the voltage of the electrical network to which a group of adjustable electric drives of the sucker pump unit is connected can be achieved by continuously recording the active power consumption of each electric drive, subsequent calculation of the optimal phases of the recorded signals of each installation relative to the base one, and adjusting the current angular position of the shaft of each electric drive to achieve the calculated value of the optimal phase of power consumption.
