FIELD: oil and gas industry.
SUBSTANCE: invention relates to control systems for oil extraction and can be employed for putting wells equipped with electro-loading centrifugal pump into stationary mode of operation after underground repair. The system of electro-loading centrifugal pump control contains block of chart dimensioning of a dynamic level of liquid, comparator, sensor of dynamic level of liquid, block of calculation of a required frequency, frequency converter, electro-loading centrifugal pump, differential block, and totaliser.
EFFECT: suggested system of electro-loading centrifugal pump control facilitates reduction of time of putting well into stationary mode of operation to condition of complete coincidence of hydraulic characteristics of pump and horizon.
