REDUCTION OF UNDERSUPPLY OF ELECTRICITY AND INCREASE OF RELIABILITY OF ELECTRICITY SUPPLY TO CONSUMERS BY USING RECLOSERS IN RURAL 10 kV ELECTRICAL NETWORKS OF GOMEL REGION

The article analyzes the status, problems and potential for reducing undersupply of electric power and increasing the reliability of consumer power supply through the use of reclosers in 10 kV rural electric networks of the Gomel region. The article presents options for installing reclosers: one recloser for sequential sectioning of a power transmission line with one-way power supply and three reclosers in a power transmission line with power supply redundancy. The criteria for optimizing the choice of recloser installation location in the network are defined: the number of disconnections of feeder consumers (line or line section), the duration of power supply interruptions for consumers of this feeder, the amount of undersupply of electric power to consumers. It has been established that for the option of installing three reclosers with power supply redundancy, the annual undersupply of electric power is reduced by 88.6% compared to the baseline option (without reclosers installation) and more than 3.3 times when compared to the options for installing one recloser on a power transmission line.
