A distribution system outage dispatch by data base method with real-time revision

摘要

A distribution system emergency dispatch technique based on outage conditions is proposed that is based on searching from a database containing precalculated solutions. Load flow solutions for possible outage cases under various conditions are simulated and calculated and kept in the database. At the occurrence of fault, a suitable solution is retrieved from this database and use to restore the nonfaulted out-or-service area. The method, which is implemented on an AT&T 3B2/300 supermicrocomputer, finds the appropriate solution in a very efficient way. A real-time computation for load-flow solutions is also suggested to improve the database for better system operation. Tests to support the technique are discussed.
