Simulation Model for the Electrical Engineering Complex of a Producing Well with a Screw Pump Unit

The paper presents the power supply circuit of the electrical complex of the oil producing well and an equivalent power circuit. A system of algebraic and differential equations has been developed. Also, a mathematical model of the electrical engineering complex of an oil producing well is designed. The system of algebraic and differential equations is supplemented by an equation of motion and a step function of stress. A simulation model of the electrical complex of an oil producing well has been developed using PSCAD software. As a result of mathematical and simulation modeling, graphs of current and electromechanical moment dependencies were obtained as a function of time in the steady-state and transient processes. Energy parameters and bordering parameters of the guaranteed start and the self-start of an electric drive of the complex under consideration are determined. It has been established that a guaranteed start-up and a self-starting of an electric drive, as well as a steady state of electric drive when exposed to external and internal disturbances in the distribution network are provided by varying all dependent and independent variables of the complex under consideration in the proposed configuration.
