Self-healing power distribution through zoning with new algoritm

چکیده مقاله

System self-healing is nothing new in power distribution networks, where auto-reclosing and auto-reclosers have been used for decades – traditionally at the individual feeder level. With increasing demands for uninterrupted power from an ever- growing group of consumers, however, operators need a broader view of the whole distribution network and its capability to limit the impact of disturbances to as small areas and as few consumers as possible.Dividing distribution networks into zones, separated by active and intelligent components, enables fault situations to be handled in an optimal way. Optimal in this context means as few affected consumers as possible, fast power restoration and with the involvement of as few personnel as possible. Central to this zoning concept are  active and intelligent node components, data communication between these nodes and the substation, and control centre systems with appropriate software.
