Abstract: The present disclosure relates to systems and methods for detection of a failed communication link and rerouting network traffic around the failure. One embodiment of a system consistent with the present disclosure may comprise a communication subsystem in communication with the data network and configured to transmit information to a recipient. The system may also include a confirmatory signal subsystem configured to generate a confirmatory signal. The confirmatory signal may be inserted into a stream of data to be transmitted to the recipient through a first communication path. Upon detection of a disruption in the confirmatory signal, a failover subsystem configured to reroute the stream of network data to be transmitted to the recipient through a second communication path. The second communication path may comprise one or more physical connections in the network that are distinct from the first communication path.

Abstract: The present disclosure pertains to distributed controllers configured to control a plurality of electrical generators in an electrical generation and distribution system. In one embodiment, a distributed controller consistent with the present disclosure may include a communication subsystem configured to communicate via a network. The communication system may receive a first plurality of time-stamped electrical parameter measurements associated with a first electrical generator. A measurement analysis subsystem may detect a change caused by an event in the measurements associated with the first electrical generator, and may detect a change in a second plurality of time-stamped electrical parameter measurements associated with a second electrical generator. A magnitude of the event may be determined based on the first and second plurality of time-stamped electrical parameter measurements. A load sharing dispatch subsystem may adjust an electrical output of the second electrical generator based on the magnitude of the event.

Abstract: Detection of which generators are connected using a common, isolated sub-grid using information from intelligent electronic devices (IEDs) in communication with each generator is disclosed herein. Each IED receives rotor position information from a rotor position detection device of the generator. Each IED may then calculate rotor speed, information of the generator and transmit such information to a central IED. The central IED uses the rotor speed information to determine which generators are connected to a common, isolated sub-grid. The central IED may further use rotor position, rotor speed, and rate-of-change-of-speed information either calculated at the central IED or transmitted from the IEDs.
