SUBSTANTIATION OF FUEL CONSUMPTION BY GENERATORS OF MICRO-GRID OF FOOD INDUSTRY AND TRADE ENTERPRISES

Abstract

The article examines a power supply system known as a local electrical micro-grid with defined electrical boundaries, which works as a single controlled object. The creation of such systems makes it possible to radically change the attitude of consumers to the management of electricity generation and distribution processes. At the same time, there is a possibility of prompt connection of consumers to the general power grid in case of overload and voltage fluctuations, which significantly increases the reliability of power supply. The development trends of the world and Ukrainian markets of gasoline and diesel generators (GDG) are characterized. Important questions were raised about electricity pricing, which should be mutually beneficial for producers, suppliers and consumers of electricity during the operation of the autonomous power supply system. The proposed technique will allow, on a scientific basis, based on the composition of the equipment, to take into account the modes of operation of the machines, to calculate the standard amount of fuel necessary for the production of the planned amount of electricity and the efficiency of its use. The advantages of using gasoline and diesel generators and their design are shown. The important requirements regarding the modes of operation of the GDG according to the level of generated power in accordance with the ISO 8528 standard, which are put forward for all their types as part of the micro-grid, are analyzed. There are four classes of regulation that determine the quality of GDG electricity from the point of view of stability, voltage and continuity. A promising way to solve the issue of energy efficiency of GDG is shown. It is assumed that in an autonomous micro-grid, which has its own sources of electricity, supplemented by an energy storage system, it is necessary to determine their nomenclature and conditions for effective operation. In order to control compliance with the regulations, enterprises must organize accounting of generated electricity and fuel consumption with the help of devices installed in accordance with the rules of technical operation.
