ELECTRIC SYSTEM submersible pumping plants and stations of electric drive control

摘要

A group of utility models relates to the field of electrical engineering, in particular to the system of the electric submersible pumping systems used in oil production, and management stations such installations. electric submersible pumping system setup consists of a submersible motor valve is connected to an AC source via a serially coupled rectifier, a switching regulator DC inductive filter, an inverter, step-up transformer and a cable line. Power station control submersible pump unit with brushless motor is composed of series-connected unit input switching valve, the switching regulator DC inductive filter, rectifier and an inverter. The technical result achieved drive system, is to obtain optimum characteristics of the adjustment system, allowing to solve the problem of adapting the submersible pump unit to the changing operating conditions of the reservoir, and the technical result achieved control station is to simplify its structure. 2 bp f-ly. 1 Fig.
