Abstract
The 400/110/10 kV network of the Hamburgisehe Electricitätswerke (HEW) comprising 10 power plants, 61 substations and 6500 transformer kiosks is under on-line control from 5 centres on 3 operational tiers. The new computerized system for the 2 lower tiers shows novel features as for workflow organisation in the control rooms, data-amendment and protection. A mimic board was not applied. Due to these conditions, the system was designed from scratch, not using standard application software.
