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:
Combining and analyzing streamed and polled electric power delivery system information is disclosed herein. A system therefore includes a plurality of IEDs in communication with the electric power distribution system and configured to provide streaming and/or polled data via a communications network. An analysis engine in communication with the communications network receives selected streaming information and requested polled information, analyzes such streamed and polled information, and provides a display of such streaming and polled information to a user.
Abstract:
Disclosed herein is a system for detecting manipulation of a global time source such as a Global Navigational Satellite System (GNSS) signal and mitigating against such manipulation. A plurality of receivers with geographical diversity receive GNSS signals, and calculate a time signal to be distributed to consuming devices. The receivers also communicate calculated time signals with other receivers. The receivers compare the time signals, and when a difference between the time signals exceeds a predetermined threshold, the receivers indicate that manipulation is likely. Such indication is shared across the network of receivers. The indication is further shared with consuming devices of the time signal from the compromised receiver. A second time signal that is not compromised may be shared with the consuming devices and/or used by the consuming devices. The consuming devices may modify their behavior when in receipt of the indication.
Abstract:
Distributed controllers in an electric power delivery system obtain measurements and equipment status, calculate derived values, and determine IED state, and share such with other distributed controllers and coordination controllers. Distributed controllers and coordination controllers further refine measurements, equipment status, derived values, and IED state. Control of the electric power delivery system is coordinated among the distributed controllers and the coordination controllers.
