In order to enhance the performance of trouble management in distribution s
ystem operations, information integration of SCADA and outage management sy
stems was investigated. Using discrete event simulation techniques, three p
ossible integration schemes were studied. This paper shows a thorough analy
sis of the system performance of integrated systems under realistic conditi
ons. Test results have indicated that the integrated system, consisting of
the two separate but related systems with connection through FDDI LAN, can
maintain the performance requirement of each system, and at the same time e
nhance the overall performance of trouble management.
