Abstract: This disclosure pertains to control systems used in electric power systems. In one embodiment, a plurality of intelligent electronic devices (IEDs) is configured to monitor a respective portion of an electric power system. Each IED may obtain electric power system measurements from the respective portion of the electric power system, determine electric power system operating conditions from the electric power system measurements, and transmit the electric power system operating conditions. A master controller may communicate with the plurality of IEDs. The master controller may comprise a communications interface configured to receive the electric power system operating conditions from the plurality of IEDs, a topology detection subsystem configured to determine a topology of the electric power system based on a common event detected by the plurality of IEDs, and an action subsystem configured to implement a control action or a protective action based on the topology of the electric power system.

Abstract: The present disclosure relates to systems and methods of sag in a power line. In an embodiment, a monitoring device may include a distance sensor and an operating parameter sensor. A processor of the monitoring device may acquire, via the distance sensor, a first distance measurement. The processor may acquire, via the operating parameter sensor, a first operating parameter measurement. The processor may provide an output signal indicating that the power line is sagging when a combination of the first distance measurement and the first operating parameter measurement exceed a first combined distance-operating parameter threshold.

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 to obtain a first plurality of time-stamped electrical parameter measurements from a first node. A measurement analysis subsystem may compare the first plurality of time-stamped electrical parameter measurements and the second plurality of time-stamped electrical parameter measurements. The first node and the second node may be associated in an electrical island by a topology detection subsystem based on the correlation. A control subsystem may be configured to implement a control action based on the association of the first node and the second node in the electrical island.

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: Disclosed herein are methods for detecting and correcting a fault induced delayed voltage recovery event in an electric power transmission and distribution system. In some embodiments, a fault detection subsystem may receive an indication of a fault in the electric power transmission and distribution system. The system may also include a load analysis subsystem to analyze a plurality of loads supplied by the electric power system and to generate an estimated response of the loads. A fault analysis subsystem may analyze a plurality of factors relating to the fault and to determine a probability of the fault generating a fault induced delayed voltage recovery event. A control system may then implement a control strategy within a control window following the fault based on the probability of the fault generating a fault induced delayed voltage recovery event and the estimated response of the at least one load.

Abstract: A condition-based monitoring system receives a plurality of measurements from sensors measuring mechanical and electrical aspects of a prime mover and a synchronous machine. The condition-based monitoring system determines a correlation between the mechanical measurements and electrical measurements to estimate parameters of the model. The condition-based monitoring system also updates the model as sensors obtain additional measurements during operation of the prime mover.
