Abstract: Systems, devices, and methods include protection functions in an electrical power system. A processing subsystem may include a processor. A memory subsystem may comprise a first memory section and a second memory section. A memory management subsystem may, in a first operational mode, enable memory access between the processor and the first memory section and the second memory section and, in a second operational mode, enable memory access between the processor and only the first memory section.

Abstract: The present disclosure relates to systems and methods for processing a stream of messages in an electric power system (EPS). In one embodiment, a system may include a configuration subsystem to receive a plurality of criteria from an operator to identify a subset of the stream of messages for real-time processing. A receiver subsystem may identify the subset of the stream of messages based on at least one criterion from the plurality of criteria. A real-time processing subsystem may receive the subset of the stream of messages from the receiver subsystem, process the stream of messages within a fixed interval of a time of receipt, and update a value based on information in the processed stream of messages. A protective action subsystem may implement a protective action based on information in the processed stream of messages.

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: Systems, devices, and methods include protection functions in an electrical power system. For example, a processing subsystem may include a processor. A memory subsystem may comprise a first memory section and a second memory section. A memory management subsystem may enable memory access only between the processor and only the first memory section to initialize the at least one protection function and, after initialization of the at least one protection function, enable memory access between the processor and the second memory section. Such a configuration may enable the protection functions as fast as possible without waiting for the functions of lesser criticality to be fully loaded and become operational.
