Determination of state of electrical equipment by spectra of wattmetrograms

Abstract

The purpose of the work is to develop a method of diagnostics and control of oil production equipment to improve energy efficiency and optimize operation modes, through the use of a wattmeter program and its spectrum. The method of diagnostics according to the wattmetrogram is based on obtaining the active power spent by the electric motor for one period of rocking of the rocker. Analysis of the spectrum of wattmetrograms makes it possible to more accurately diagnose defects of this equipment. Thus, control over the spectra of the wattmetrogram is a more accurate and promising method of diagnosing equipment. Materials and methods: In the development of this issue, both domestic and foreign literature was used. The technical data of the control stations and sensors were used on the basis of actual electrical equipment. The prospects and benefits of using diagnostic options weltmetropole: relatively small number of sensors (current and voltage transformers); ability to measure the electric power consumed by the drive; ability to integrate with automated systems of technical and commercial electricity metering; the task is relevant already today, but it is quite promising in the future, due to the rapid development of technologies that allow for digital processing of wattmetrograms; use of these technologies in practice; economic advantages over similar representatives of this segment; service life of more than 20 years; ability to work in a wide temperature range -40 — +60.
