Control System Improvement of the Electric Drive of the Pumping Unit for Oil Production

This article considers the technological and climatic features of oil production in the Mangistau region. The supplied electric drives of the pumping units and their remote controls are not designed for the climatic conditions of Western Kazakhstan according to the technical specifications. Imported intelligent remote controls fall into disrepair after a couple of years. In this article the authors drew their conclusions and determined the main requirements for electric drives of the Western Kazakhstan oilfield by analyzing the state of development of electric drives of the pumping units supplied from different countries. As well as the structural and virtual diagram of the electric drive of the pumping units according to the frequency converter - asynchronous motors system, the synthesis of parameters and the stability of which is solved by the method of nonlinear correction, allowing to conduct research in wide variations of the control parameters of the “frequency converter - asynchronous motors system”.
