The most important factor in improving the energy efficiency of enterprises and organizations of the State Reserve is the rational use of fuel and energy resources. Oil depots are not the most energy-intensive in the State Reserve system, but reducing electricity consumption is an important factor in reducing the cost of their products. During the past 10-15 years, the world has seen the widespread and successful introduction of frequency-controlled electric drive to solve various technological problems in many sectors of the economy. Installation of frequency converters on the pumping equipment of oil depots gives the chance of smooth regulation of modes of their work. At the same time loading of electric motors of pumps will be optimum, and losses of the electric power are minimum. At oil depots, the main consumer of electricity is pumping equipment. The technological process of operation of these enterprises involves reverse pumping of fuels and lubricants between tanks and rail and tank trucks. The peculiarity of oil depots is the uneven loading of equipment due to different needs in the number of pumped oil products over time, so the loading of the pumping station will also be uneven due to different pressure and supply in the pipelines. To maintain the set mode of operation of the pumping station when changing external factors affecting its operation, it is necessary to monitor and regulate the modes of operation of pumping units. This function can be divided into two areas: regulation of hydraulic modes of operation of pumps, which is used at oil depots, and regulation of energy efficiency of pumping station equipment. The calculation of technical and economic indicators of the introduction of frequency-controlled electric drive is performed on the example of state enterprise "Aystra" Chernihiv. The main purpose of the plant is the reception, storage and shipment of petroleum products of the state material reserve. Production capacity for heavy-duty rail tanks and vehicles allows for freight operations with a capacity of 350 tons per hour.
