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.

Messaging in an electric power system

A single point to modify a behavior of intelligent electronic devices (IEDs) between active and testing modes is disclosed herein. The IED may include a variety of logical nodes, each with a behavior object related to the active or testing mode behavior of the IED. A single testing mode selection point of the IED is used to modify each of the logical nodes to change between active and testing modes. The testing mode selection point may be a logical input. The testing mode selection point may be a physical switch on the IED.
