    Abstract: Techniques and apparatus presented herein are directed toward monitoring an electric power delivery system to detect and locate a power generation event. A power generation event may include a tripped generator, a loss of a transmission line, or other loss of power generation. To detect the event, an analysis engine may receive and monitor input data. A detection signal may be generated based on the input data. Upon detecting the event, the analysis engine may determine a source and propagation of the event through the delivery system. Based on the source and propagation of the event, the analysis engine may determine the location of the event. The analysis engine may generate an overlay with the input data to provide the location and other information about the event to a user such that remedial action can be taken to resolve the event and restore the lost power generation.

    Abstract: The present disclosure relates to systems and methods of detecting discharge events on power lines. For example, a system may include an acoustic sensor that detects a sound wave emitted from a power line. The system may include a radio frequency (RF) sensor that detects a radio wave emitted from the power line. The system may include electrical sensor circuitry that detects an electrical parameter of power being delivered on the power line. The system may include a processor that determines that a discharge event has occurred based on the sound wave, the radio wave, and the electrical characteristic. The system may provide an output signal indicating that the partial discharge event has occurred.

    Abstract: Disclosed is state trajectory prediction in an electric power delivery system. Electric power delivery system information is calculated from measurements by intelligent electronic devices (IEDs), and communicated to a state trajectory prediction system. The state trajectory prediction system may be configured to generate a load prediction profile. The load prediction profile may provide a predicted response of a load at a future time. Further, the state trajectory prediction system may be configured to generate a generator prediction profile that provides a predicted response of a generator at a future time. The state trajectory prediction system may generate a state trajectory prediction based, at least in part, on the load prediction profile and the generator prediction profile. The state trajectory prediction may represent a future state of the electric power delivery system.
