CRAFT: On-line expert system for customer restoration and fault testing
- Washington Univ., Seattle, WA (USA). Dept. of Electrical Engineering
The purpose of the rule-based expert system, CRAFT (Customer Restoration And Fault Testing) is to assist power dispatchers with fault isolation and customer restoration in multi-tapped transmission lines equipped with automatic switches. CRAFT is able to perform reasoning to derive the status of unsupervised automatic switches. The CRAFT system is operating on-line at the control center of Puget Sound Power and Light Company (Puget Power). The expert system was developed by the University of Washington (UW) under the sponsorship of EPRI with cofunding from the National Science Foundation and Puget Power. The on-line CRAFT system is implemented on an expert system computer data-linked to the SCADA computer in the control center. In Puget Power's control center, a Micro VAX II computer is linked to the MODCOMP CLASSIC II SCADA computer to perform the functions of fault testing and substation restoration. The CRAFT system contains approximately 450 rules written in the rule-based language, OPS83. The typical response time of CRAFT is approximately 13 seconds. 15 refs., 17 figs., 2 tabs.
