Background. The paper considers the city electric network of Dushanbe for determining the damage to cable and overhead lines, as well as transformer substations of 6–10/0.4 kV. Based on the collected materials of emergency shutdowns by months, the obtained distributions of the above objects in 2017–2018 are obtained.
Materials and methods. According to the statistics of emergency outages for the autumn-winter and winter-spring periods of 2017–2018, in order to identify the effect, the dependences of damage to the elements of the urban electric network on air temperature and rainfall were obtained. An equation is proposed for predicting power consumption for the city of Dushanbe, as well as the possibility of applying it to other cities of the Republic of Tajikistan, taking into account the factorial conditions of the terrain.
Results and conclusions. Based on the obtained equation, an algorithm for monitoring power consumption is proposed with the introduction of this algorithm into the function of smart means of electricity metering in order to maintain the operating parameters of the distribution network, which can increase the reliability of power supply in both Dushanbe and all cities of the Republic of Tajikistan.
