Abstract

See full text

A power management architecture for an electrical power distribution system, or portion thereof, is disclosed. The architecture includes intelligent electronic devices ('IED's') with the capability to monitor and control attached slave devices, and provide capability to communicate between multiple devices in a variety of communication protocols. A master IED in the master/slave architecture performs power management functions on the data received from the slave IED's. Further, the IED's with master functionality provide web server capabilities, allowing a user to view processed data over an open Internet protocol, such as HTTP ('Hyper Text Transfer Protocol').
