Reliability Indicators of Urban Electric Network Schemes for Supply of Second and Third Category Consumers
Abstract
The paper considers two schemes of the urban distributive electric network for supply of the second and third category consumers for whom indicators of reliability have been determined.
As for a network scheme of the 2nd category it has been determined that while installing low-oil and vacuum switches at a distributive point the most remote transformer substation has the highest non-availability factor which is higher of the corresponding non-availability factor of the nearest transformer substation by 1,21–1,23 fold accordingly.
As for a network scheme of the 3rd category consumers it has been obtained the data that reliability of consumers receiving supply from bus-bars of transformer substations with 0,38 kW voltage changes significantly (by 1,2–1,9-fold) while changing a breakpoint of the network with 10 kW voltage.
