Computer-based supervisory control and energy management system for the city of Cape Town

摘要

Cape Town City Council is responsible for the supply of electricity to the city area. To achieve this, the council owns and operates thermal and pumped-storage power stations and extensive HV transmission and LV distribution networks. Power is also purchased from the national supply authority. To assist the operators in their duties a new computer-based control centre has been developed and was commissioned in 1984. Because of the unusual mix of power sources special software had to be developed for energy management purposes. Descriptions are given of the functional and practical aspects of the control centre, and of associated hardware and software facilities and also some commissioning experiences.
