摘要： The present disclosure pertains to systems and methods to share data in a point-to-point system. In one embodiment, a system to share point-to-point information may be used in an electric power system, and the system may include a communication interface to communicate using a point-to-point protocol using at least a first port and a second port. A point-to-point information sharing subsystem may receive an indication that point-to-point information received on the first port is to be shared on the second port and may configure the second port to share point-to-point information received on the first port. In some embodiments, a delay associated with the communication link may be added to the shared point-to-point information prior to transmission.

摘要： Systems and methods are disclosed to monitor real-time digital data for degradation. In one embodiment, an intelligent electronic device (“IED”) in an electric power system may include an interface to receive a stream of digital data, the stream of digital data comprising a plurality of data frames. A protective action subsystem may monitor the sampled digital data and implement a protective action based on the stream of sampled digital data. A digital data degradation detection subsystem may analyze a plurality of digital metrics associated with the plurality of data frames and make a determination regarding degradation of a communication channel based on whether the plurality of digital metrics fails at least one threshold. In response to the determination, the digital data degradation detection subsystem may implement a response to the determination that the plurality of digital metrics fails at least one threshold.

摘要： An intelligent electronic device (IED) of an electric power distribution system includes processing circuitry and a memory that includes a tangible, non-transitory, computer-readable comprising instructions. The instructions, when executed by the processing circuitry, are configured to cause the processing circuitry to receive operating data associated with the electric power distribution system, determine whether the operating data matches with expected operating data, generate a connectivity association key (CAK) based on the operating data in response to a determination that the operating data matches with the expected operating data, and establishing a connectivity association based on the CAK.

摘要： Systems, methods, and devices are provided for determining a maintenance mode of one or more merging units of an electric power delivery system using an intelligent electronic device that may rely on communication from wired (or wireless) electrical measurement devices. The intelligent electronic device may be a line relay. The merging units may provide data to the line relay including at least one bit indicating a maintenance mode of each merging unit. If a maintenance mode bit from a particular merging unit indicates that the merging unit is in the maintenance mode, logic of the line relay may determine if a maintenance mode override is received. If so, the line relay may disregard the maintenance mode bit and process the data from the merging unit. If the logic determines that the merging unit is in the maintenance mode, the line relay may force data from the merging unit to zero.
