An online operational expert system with data validation capabilities (for power systems)
TLDR
The capabilities of CRAFT are extended by adding two new knowledge bases with rules to determine the status of unsupervised automatic switches and to detect the presence and location of a manual switch with an incorrect status following a fault.Abstract:Â
The implementation and operation of an expert system in a control center environment is discussed. CRAFT (customer restoration and fault testing) is a rule-based expert system which is capable of locating the faulted section of a transmission line equipped with automatic switches and circuit breakers. In this study, the capabilities of CRAFT are extended by adding two new knowledge bases with rules to determine the status of unsupervised automatic switches and to detect the presence and location of a manual switch with an incorrect status, following a fault. An approach to appending a separate expert system computer to the SCADA system is developed. Software and hardware interfaces are designed and implemented. The completed implementation is operating online. The implementation represents a step toward practical application of expert systems for real time operation of power systems. >read more
