Determining computational aspects of submersible electric centrifugal pump installations electric motors parameters

There is ratios estimate accuracy for determining the electromagnetic parameters of submersible asynchronous electric motors (SEM) of electric submersible pumps (ESPs) installations directly on the stator current damping curve i1 (t) recorded from a stationary rotor. Software efficiency was checked up, as it is necessary for its implementation by means of a mobile unit carrying out SEM identification in terms of electro repair shops or on the multiple well platforms surface. Test transient respond software processing error does not exceed 1.5% The discrepancy of 5% was obtained for T3 sub transient time constant. SEM basic electromagnetic parameters error determining was obtained not more than 6.2%.
