Abstract

Rocking machines of oil (RMO) are the main elements in the Russian oil industry in the field of low-yield wells. And increasing the energy efficiency of these machines is one of the most promising tasks in the interests of the oil and gas industry in Russia.The use of intelligent energy-saving stations for controlling the machine-shaker of oil on the basis of synchronous engines makes it possible to optimize oil production, by increasing the volume of production and saving energy resources. The main disadvantage of these stations is high cost, which is a deterrent for widespread use.One of the solutions to this problem is the use of a method that does not use the rotor position sensor, the so-called "sensorless method". However, all works related to the use of the "sensorless method" refer to the control systems of asynchronous motors.In this paper, the advantages of the control systems of a rocking machine on the basis of synchronous motors in front of asynchronous motors will be presented, the variants of motor control and the execution of the "sensorless method" are considered. Mathematical models of all elements of the control station are presented: rocking machine, synchronous motor, vector control system.
