Abstract

The development and implementation of a Prolog expert system using computer graphics is reported for the online monitoring and control of the 50 Hz single-phase overhead current collection catenary system currently in operation in Hong Kong. Running as an online consultant on a personal computer, this expert system allows operating personnel to perform intelligent network switching on a graphic picture representing the whole of the catenary line system. Users are able to find out effects of their own choice of switching sequence by examining graphic displays. Valid switching brings about changes in display configurations and colours to record changes in the on/off status of circuit breakers or isolators, or the relocation of supply points
