Method for determining the parameters of a substitution scheme for an electromechanical module with an increased electromagnetic momentwith increased electromagnetic torque

THE PURPOSE. Consider the problems of determining the energy parameters of electrical equipment elements of electrical complexes for oil production with submersible electric centrifugal pumps. Develop a methodology for determining the parameters of the equivalent circuit of an electric motor for oil production when connecting compensating devices to the terminals of the electric motor of a submersible pump. Develop a methodology for calculating the energy performance of electrical equipment elements of an electrical complex with electric centrifugal pumps. Carry out simulation modeling of an electric motor for oil production with a directly connected compensating device.

METHODS. When solving the tasks set, optimization methods were used in terms of efficiency, power factor correction methods, methods for calculating the electromagnetic field by finite elements, methods of mathematical and computer modeling in the ELCUT software package.

RESULTS. Improving energy efficiency and reducing costs in the operation of submersible pumping units for oil production is an urgent problem and dictates a reasonable solution. The price of extracted oil depends on the following indicators, such as climatic conditions, equipment used, depth of oil deposits, remoteness of the field from central roads, and so on. The most significant energy-intensive processes in oil production include: electromechanized oil extraction, oil transportation, reservoir pressure maintenance system. A technique for finding the parameters of the equivalent circuit of an electric motor for oil production and a study of the effect of reactive power compensation on an electric motor in an oil well when compensating devices are connected to the terminals of the electric motor of a submersible pump are proposed. A method for calculating the energy performance of electrical equipment elements of an electrical complex with electric centrifugal pumps is proposed. The calculation of a compensating device in an oil well for an electric centrifugal pump with a frequency-controlled electric drive must be implemented taking into account the highest value of the output network frequency. Simulation modeling of an electric motor for oil production with a directly connected compensating device was carried out to establish the effect of a reactive power compensating device inside an oil well on the rotating electromagnetic moment of an electric motor for oil production. The indicators of the electromagnetic torque and the electromagnetic field of an electric motor for oil production without a connected compensating device and with a directly connected compensating device are presented, the supply wires of which in the first version are laid along a single route and in the second version are laid at an angle of 120 ° relative to each other in the corresponding grooves of the stator winding of the electric engine for oil production.

CONCLUSION. When conducting a study of the effect of a directly connected compensating device on the electromagnetic torque of an electric motor for oil production, it was determined that additional windings of a directly connected reactive power compensating device, laid at an angle of 120 ° relative to each other in the corresponding grooves of the stator winding of the electric motor, increase the efficiency and electromagnetic torque of an electric motor for oil production by 11% and 15%, respectively.
