Computer based distribution control rooms-operational experience

For several years, the North of Scotland Hydro-Electric Board has operated a prototype distribution control room based entirely on a network diagram displayed by computer driven colour monitor displays. The initial system provided workstations for two control engineers and also provided a graphics interface to an existing telecontrol system. This system has been in daily use since May 1985, as the sole means of controlling all operations on the HV system. The authors outline the engineering problems, operating experience and benefits of such a system.<
