Introduction

At present, one of the most important tasks of each enterprise is the saving of material resources, since it is material costs that make up the majority of production costs, on which the value of profit directly depends. And profit is the main source of livelihood of the enterprise.

Rational and economical use of material and fuel and energy resources is of great importance for each specific enterprise of our state.

The consumption of material resources, including electrical energy, is their production consumption. The cost of production covers all the amount of material resources expended by the enterprise directly for the implementation of the program for the production of products. Expenditure of material resources is also carried out for repair needs, maintenance of intra-plant transport, provision of subsidiary farming, cultural and domestic needs. Consumption of material resources is characterized by a general consumption for the implementation of the entire production program in the reporting period and their specific consumption - the consumption of a unit of marketable output.

The main condition for reducing the costs of raw materials and materials for the production of a unit of production is to improve production technology, reduce production costs, use advanced materials, introduce technically sound standards for the costs of materials and fuel and energy resources.

The national treasure of the Republic of Belarus is its natural, fuel and energy resources, as well as its technical and intellectual potential. Increasing the efficiency of the use of technical capacity, as well as all types of resources within the country with the use of energy-saving technologies in industry on a large scale, is the most important task of resource-saving policy.

The purpose of the thesis is to create a software module for processing electricity meter data at the enterprise of Minskenergo, a branch of Energosbyt.

To achieve the purpose of the thesis, it is necessary to solve a number of problems:

- analysis of the technological process in order to determine the place, role and significance of the software module for processing electricity meter data in the technological complex;

- analysis of the power supply system;

- the definition of the hierarchy of the management and control system, as well as the structure of AMRMS;

- development of a software module for processing energy meter data;

- a description of the software ASKUE;

- determination of technical and economic relevance, necessity and possibility of modernization of the system;

- Analysis of the existing system of organizational and technical measures to ensure labor protection and safety during operation, upgraded system.
