1. A power outage restoration system for managing a power network including a plurality of switching devices, said power outage restoration system comprising:
- an outage management system having a network model of said power network, said outage management system including an outage engine that uses said network model for determining restoration switching plans;
a plurality of local restoration controllers in communication with said outage management system, each said local restoration controller having a distinct local restoration controller area of responsibility which is a portion of said power network, each said local restoration controller including a trimmed network model correlating to the respective local restoration controller area of responsibility, each said local restoration controller further including a switching analysis engine that uses said trimmed network model for determining said restoration switching plans; and
wherein said a local restoration controller is operable to detect faults the an associated area of responsibility, when a fault is detected the respective local restoration controller switching analysis engine attempts to create a restoration switching plan, and if said switching analysis engine fails, a request is sent to said outage management system for said outage engine to create a restoration switching plan.

9. A method of managing a power network including a plurality of switching devices, the method comprising:
-
providing an outage management system having a network model of said power network, said outage management system including an outage engine; providing a plurality of local restoration controllers in communication with said outage management system, each said local restoration controller having a distinct local restoration controller area of responsibility which is a portion of said power network, each said local restoration controller including a trimmed network model correlating to the respective local restoration controller area of responsibility, each said local restoration controller further including a switching analysis engine; monitoring said power network by said local restoration controllers; if a fault occurs in an area of responsibility, using said switching analysis engine at the respective local restoration controller to determine a local restoration switching plan; if said local restoration switching plan is deficient, using said outage engine to determine a global restoration switching plan; and executing said global or said local restoration switching plan to restore power to one or more outaged sections of said power network. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method of managing a power network including a plurality of switching devices, the method comprising:
-
detecting a fault on the power network; creating a restoration switching plan comprising a sequential series of switching operations including manual switching operations and remote controllable switching operations, said restoration switching plan being executable to isolate a faulted portion of said power network and to backfeed outaged portions of said power network; sequentially executing each said switching operation; and wherein if said switching operation is a manual switching operation, transmitting a command to a ground crew to manually execute said switching operation and if said switching operation is a remote controllable switching operation, transmitting a switch command to the switching device to execute said switching operation.
