Power distribution network fault management

摘要

A fault interrupt device (134) is tripped by a fault (160) in a power distribution network (10). A distributed automation controller (DAC) (140) determines a location of and isolates the fault. Power is restored upstream of the fault and downstream power requirement vs. power availability from a secondary source(s) is assessed. The secondary source(s) is connected to the downstream portion if power available is sufficient or after nodes are deactivated to bring power requirements below power available. If a second fault (162) occurs, it is also located and isolated, such as by communication between affected partition DACs of the power distribution network.
