Justification of the feasibility of use of frequency converters in control stations of submersible centrifugal pumps

The article considers the problem of determining conditions under which use a frequency converter in submersible pump control station leads to reduction electrical energy costs and becomes efficient from an point view. Analytical expressions are given that allow calculating specific during artificial lift oil production for case when operating mode well flow rate provided by wellhead choke throttling. At same time, special attention is paid rotation speed asynchronous motor, ensures required location on pressure characteristic. Formulas also make it possible calculate set station. An analytical expression has been found determine supply voltage, provide with regulation motor. It proposed, using above expressions, iterative method performance, at cubic meter liquid will be equal both without it. example such boundary value performance hypothetical given. shown decrease relative limiting consumption
