The parameter identification of submersible motors of electrical centrifugal pump units for oil production

Reliable and power efficient controlling of electrical submersible pump units (ESP) realizes one of the most important means of oil-production; it is possible when effective means of identification of electromagnetic and mechanical parameters of submersible electric motors (SEM) are present. The article presents the results achieved due to an analysis of calculated ratio for parameter identification of the equivalent network of SEM based on registration of transition characteristics of the stator current at a fixed rotor. A feature of the identification is the possibility of its realization at multiple well platforms of oil-field due to sets of control stations (CS) of ESP without additional extra budgetary recourses.
