Abstract

The article is devoted to the actual problem of how to improve the reliability of the urban electric network. Based on the statistical analysis of the breakdown of electrical equipment in urban distribution networks in Dushanbe for the periods of 2017-2018 and for the reasons of damage leading to these emergency outages, the factors that affect the distribution of damage leading to emergency outages are identified. Taking into account the identified factors, a power consumption forecasting system is proposed that takes into account the local conditions of the city of Dushanbe. it allows us to suggest a way to control the operating parameters of the electric network, thereby increasing the reliability of the city's electric network in Dushanbe based on the recommendation of power consumption standards. Implementation of the control of the proposed method for improving the reliability of power supply to the urban electric network is proposed on the basis of the functionality of modern smart electricity metering using the control algorithm. To implement the control algorithm, schematic design for receiving and transmitting information from smart power metering to the data collection centre is proposed.

Highlights

The effectiveness of any electrical networks, including city networks, is ensured by maintaining the allowable specific loads, both at maximum hours and throughout the day and month
Using modern smart electricity metering [19,20,21,22,23,24,25], it is possible to monitor the state of electric networks in our cases, the proposed energy consumption standards for Dushanbe and the cities of the Republic of Tajikistan [1, 2, 13]
AND DISCUSSION we would like to offer the following electricity consumption standards controlling algorithm both within the hours of maximum loads and during the whole day and month for the cities of the Tajikistan Republic adding this algorithm into the automated system of electric power account Figure 8

Summary

Introduction

The effectiveness of any electrical networks, including city networks, is ensured by maintaining the allowable specific loads, both at maximum hours and throughout the day and month. Exceeding specific loads from the normative leads to a deterioration in the reliability of the power supply system [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18]. The increase in electrical load is associated, in particular, with the climatic and meteorological conditions of the area and in the absence of warm-hot water supply for urban consumers, this factor may be the main reason for the increase in electric load, which subsequently can lead to a violation of the quality of electric power and the life of electrical equipment and undersupply of electricity. To increase the reliability of Dushanbe city networks, it is necessary
