摘要： 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.

摘要： A conductor-mounted device (CMD) used to signal an intelligent electronic device (IED) of the existence of a fault on a portion of the electric power delivery system is described herein. The CMD may provide a heartbeat signal to the IED. The CMD may provide a fault signal to the IED. The CMD may be powered via a parasitic current draw on the conductor to which it is mounted. An IED may use a fault signal and/or LOC signal from a CMD to coordinate a high-impedance fault detection and/or downed line events.

摘要： Systems, methods, and apparatuses for one-way communications are disclosed. A system includes a transmitter, a first receiver, and a second receiver. A transmitter transmits one or more messages on one or more channels according to a predetermined, pseudo-random channel hopping protocol. The receivers receive said transmissions according to the order of the pseudo-random channel hopping protocol. Methods for re-syncing the one-way system in the event of a power loss or other event causing desynchronization. Default waiting channels are established for the receivers once a certain number of channel detection periods according to the one-way communication protocol result in no detected signals.

摘要： The present application discloses detecting manipulation of GNSS signals using a second time source. If two or more GNSS constellation signals are being detected, the phase error between the GNSS constellation signals may be monitored. When the phase error drifts, then manipulation is determined. The integrity of a GNSS constellation signal may be monitored using an internal time source such as a crystal oscillator by monitoring a slope of the free running counter at the detected rising edges of a pulse-per-second signal from the GNSS constellation. If more than two GNSS constellations are monitored, a voting scheme may be used to determine the manipulated GNSS constellation.

摘要： Disclosed herein are a variety of various systems and method for adaptive holdover time error estimation. In one embodiment a system may include a local time source configured to generate a local time signal and an external time source interface configured to receive an external time signal. A time source subsystem may be configured to compare the local time signal and the external time signal and to determine a temperature-dependent signal drift rate of the local time signal relative to the external time signal. The time source subsystem may be a time-dependent signal drift rate of the local time signal relative to the external time signal. A holdover subsystem may detect a loss of reception of the external time signal during a holdover period and may estimate a total maximum error based on an estimated maximum time-dependent error and an estimated maximum temperature-dependent error.

摘要： Disclosed herein are various systems and methods that may improve the transmission of data over low-bandwidth communication channels in an electric power delivery system. Devices communicating across a low-bandwidth communication channel may implement several approaches, according to various embodiments disclosed herein, to reduce the data transmitted across the low-bandwidth communication channel and to prioritize the transmission of time-sensitive and/or more important information with respect to other data. Various embodiments disclosed herein may inspect packets to be transmitted across a low-bandwidth communication channel in order to identify high priority data. High priority data may be time-sensitive information, and accordingly, transmission of such data may be prioritized over other data in order to reduce transmission latency of the higher priority data.
