ComEd Advances System Reliability

摘要

Existing distribution automation schemes improved through use of advanced reclosing technology. Commonwealth Edison (ComEd), a unit of Exelon Corp., provides electrical service to most of northern Illinois, U.S., and is continually striving to improve the overall reliability of its distribution system to provide the highest possible level of service to customers. One effort over the course of the last seven years has been to deploy large numbers of traditional loop-scheme (LS) reclosers on its 12-kV distribution feeders. As these efforts to improve reliability have progressed over the years, ComEd has recognized the need to use reclosers with advanced technology to further leverage the return on investment of its existing distribution automation (DA) equipment. It has been determined this advanced technology can be deployed effectively within traditional LS recloser schemes to further minimize the number of customers affected when a fault occurs on the distribution system with minimal modification to the existing devices.
