The analysis of the frequency-controlled drive currently used on the technological equipment of the Volgogradneftemash enterprise is presented. Taking into account the peculiarities of the pumping and ventilation equipment installed at the enterprise, the principles of regulation are determined and the influence of a frequency-controlled drive on the quality of electrical energy is evaluated. The negative influence of the frequency-controlled drive of ventilation and pumping equipment on individual indicators of electricity quality was noted. In order to reduce this influence, an energy-saving device has been proposed for installation. The issues of the possibility of using an energy-saving device at the facility are considered, as well as an analysis of its efficiency during operation from the point of view of improving the quality of electricity in the internal power supply system of the Volgogradneftemash open Joint stock company is carried out. The use of the device is an effective solution, since it leads to high energy efficiency of technological equipment by reducing current surge, suppression of higher harmonics and electromechanical interference.

The article presents the issues of the introduction of active energy complexes into the Russian energy system as an element of distributed generation for commercial and industrial consumers. In 2020, a pilot project was launched in Russia to create micro–energy systems for commercial and industrial consumers - active energy complexes. This form makes it possible to increase the efficiency of the Unified Energy System of Russia due to the possibility of optimizing the external network infrastructure and will allow businesses to reduce the cost of energy supply. The prerequisites for the development and implementation of the concept of active energy complexes in Russia were the increase in the cost of energy supply to enterprises, as well as the development of distributed generation and digital technologies.
