Abstract

The relevance One of the key directions of innovative development of the electric power industry until 2035 is the transition to digital active-adaptive networks with a distributed intelligent automation and control system. In this regard, in conditions of increasing demands for improving the quality of electricity and reducing losses in networks, it is necessary to improve the voltage and reactive power regulation system in electric networks, which should be based on the widespread use of modern means of regulating voltage and reactive power, as well as automatic control systems, including centralized ones. The main effect of reducing technical losses in electric networks, as shown by the energy survey of FGC UES JSC, the experience of foreign electric grid companies and the analysis of the modes of operation of the Unified National Electric Grid, can be obtained by optimizing the established modes of operation of the electric grid in terms of reactive power and voltage levels in automatic mode, provided that the condition of regulating devices is constantly monitored. The absence of a system for remote monitoring of the parameters of power factor correction devices in the power supply systems of enterprises leads to untimely detection and elimination of failures in the operation and operation of the network without power factor correction. Aim of research To analyze the energy parameters of the power supply system of oil production facilities, to identify deviations of voltage values and power factor from regulatory requirements. To investigate the effectiveness of the use of low-voltage automatic power factor correction units in the power supply system of an oil-producing enterprise. Research methods The study of scientific literature, field research at oil pumping facilities, energy surveys, computer modeling. In order to identify the technical and economic efficiency of the use of low-voltage automatic power factor correction units, pilot field tests were conducted in one of the oil and gas producing enterprises of the Tatneft PJSC. Results Energy surveys of in-field pumping facilities, oil treatment and reservoir pressure maintenance of Tatneft PJSC have shown that the value of reactive power in the networks of power supply systems of these enterprises significantly exceeds the standard. As a result of pilot field tests, it was revealed that the use of automatic power factor correction units in automatic mode ensures the stabilization of the power factor at the level of standard values, excluding under-compensation or overcompensation of reactive power, while reducing electricity consumption by an average of 2.4 %. The remote monitoring system allows you to monitor the operating mode and technical condition of all elements of the capacitor plant, timely perform maintenance of contactors to ensure the operability of the installation.
