Data Communications for Critical Power Management Systems

Critical power management systems provide advanced control and monitoring capabilities and interactive tools for assessing and responding to power system conditions. To do so, power system equipment and devices must be connected to a central platform that processes incoming data and provides resulting outputs using power management software. This document describes the networks used to carry communication signals, the protocols used to communicate power information, and the network devices needed to connect equipment and convert signals.


In power management systems, power devices connect to a central platform that records, evaluates, and responds to power data. Inputs can consist of any combination of digital, analog, serial, and Ethernet inputs that are transmitted over copper wire or optical fiber. Because these systems typically receive and send data using TCP/IP, other types of inputs and outputs require conversion to or from this protocol.
