Features of the functional reliability of 0.4-10 kV distribution networks

Abstract

Abstract The article is devoted to the study of the influence of regime restrictions on the functional reliability of distribution networks of 0.4-10 kV. This level of the network is largely determining the values of indicative indicators of reliability of power supply. In the work, by the example of the analysis of the reliability of power supply of two energy regions, the significance of the influence of the regime factor on the uninterrupted power supply is proved. Due to the complexity of the topology and the variability of the flow distribution, it is proposed to use the decomposition method for calculating the reliability and recoverability of network nodes. The expediency of calculating indicative indicators of the reliability of electricity supply at the stage of network design is shown, since today, in Russia, the economic efficiency of the functioning of territorial network companies is largely determined by the level of reliability due to the existing relationship between reliability indicators and the tariff for the transmission of electric energy.
