Semi-natural simulation system of a sucker-rod pump

Abstract

This article describes the development of a semi-natural torque load simulation system on an induction motor shaft that simulates the operation of a sucker-rod pump (SRP). For semi-natural simulation, a laboratory bench with an induction motor (IM) and direct current motor located on the same shaft is used. The four-link mechanism kinematic scheme of a sucker-rod pump and the implementation of software modules for calculating load torque are presented. The main results of simulation tests are given.

Software Complex for Sensorless Control of an Electrical Submersible Pump

“…First, the calculation requires accurate determination of a large number of different ESP parameters, while some parameters are dynamic, while others are difficult to accurately determine value even with sensors and other special measuring equipment. Secondly, this method require redundant steps to get the result, which are the placement of digital manometer and speed change at the operating state, which can be complicated from unit to unit [51]. Therefore, the ESP flow rate must be estimated using other indirect methods.…”
