Abstract

The solution of the actual scientific problem is offered: development of methods and models of reduction of the cost of the consumed electric power on the basis of introduction of system of technical monitoring through introduction of IIOT technology (Industrial Internet of Things). One of the ways of the management of energy consumption modes efficiency increasing is based on the construction of control models of refrigeration units, the initial parameters of which are: internal temperatures; outdoor temperatures; correction of operating modes due to the opening of doorways; the level of filling the refrigeration unit; temperature of freezers. The criterion and relevant model of reducing the costs for consumed electricity was developed. It takes into account a number of restrictions imposed by the technological process and the requirements for the quality of storage of products. Reducing of the costs can be achieved in accordance with the rates differentiated by zones of the day that require the transfer of energy consumption to the night and half-peak zones of the tariff, minimizing consumption in peak and halfpeak hours. Realization of this is possible due to change of temperature modes of fridges - more cooling in hours of low payments and endurance on the minimum temperatures in hours of the maximum payments for electric energy. Based on the proposed models and methods, algorithms for assessing energy efficiency and obtaining a short-term forecast of energy consumption for planning the volume of electricity procurement have been developed. The software developed by us allows to control energy consumption and temperature modes of refrigeration units. Full control is provided: indoor, outdoor and freezer temperatures; facts of opening doors and their duration; the level of filling of the refrigeration unit. Development of methods and models of reduction of the cost of the consumed electric power on the base of introduction of systems of technical monitoring is offered. Based on the proposed model and modern IIOT (Industrial Internet of Things) technology, computer programs have been created that use modern libraries for input, processing and presentation of information, allowing them to be integrated into modern production management systems.
