Object. The object of research is the modernization of the drives of oil pumping units through the use of synchronous motors and adaptive control systems. Field of application: electrical equipment for oil pumping units.The purpose of the work is to identify inventions in the field of electric drives based on Russian highly efficient synchronous motors for oil pumping machines, to determine the advantages and disadvantages of modern developments in this field.Methods. This analysis will reveal the strengths of the drive being developed and most competitively present them. An important point is, and checking the possibility of patenting in this area, i.e. check for patent purity.Results. As a result of the study, the most significant inventions (based on the patent analysis of the Russian Federation) were identified in the field of sucker rod pump control stations, dynamometry, and wattmetry, which are presented in the work, they provide a brief overview, provide basic information and novelty.Conclusion. A literature review showed that the issues of control stations for sucker rod pumps, dynamometry, wattmetry, and the development of synchronous electric motors are rather deeply covered, on the other hand, the literature does not sufficiently reflect the problems of frequency regulation of synchronous motors, as well as the capabilities of intelligent control stations that would allow increase the level of oil production, optimize the technological process, significantly reduce the influence of the “human” factor improve production safetyThus, the need to create a competitive electric drive for oil pumping machines is the use of “smart” control systems that will regulate the operation of the well due to adaptive (based on automatic analysis of dynamograms and wattmetergrams) private regulation. |
