Estimating How the Start-Up of High-Voltage Ground Electric Drive of Oil Transfer Pump Impacts the Oil Well Electric Motor Operation

The article presents a Matlab Simulink computational model for an electrical complex of a production well with a chain drive and an oil transfer pump with an asynchronous drive. The model is used to study the effect that starting of an oil transfer pump drive has on the downhole pump electric drive. The simulation was carried out with and without account for the reactive power compensation in the electrical complexes considered. The two simulation options mode parameters are specified and compared. The comparison confirms the increased stability of the electrical complex operation with capacitor units in use when in supply voltage decreases at pumping units electric drives terminals.
