Claim:
1. An apparatus for substation automation of a power system, the apparatus comprising: circuitry configured to: receive input data characterizing at least one voltage and/or current related to a component of a power system, interface to an external synchronization network, implement logical nodes, map information to and/or from at least one of the logical nodes to first communication protocol, determine power quality information depending on the input data, associate the power quality information with timing information supplied by the circuitry, wherein the logical nodes comprise at least one of frequency variation, current transient, current unbalance variation, voltage transient, and voltage unbalance variation, map information to and/or from at least one of the logical nodes to a second communication protocol, and forward the determined power quality information with associated timing information to a plurality of electronic devices external to the circuitry via a plurality of physical ports dedicated to specific communication protocols for monitoring, protecting, and controlling a power quality of an electrical power grid of the power system.
