30 April 2004 - A substantial contract to upgrade the operator control system at the Medway Power Station has been completed by ABB, working with site engineers. The new operator display system provides real state-of-the-art management and control facilities and is the first major upgrade to the control system since the plant was opened in 1996.
The dual fuel combined cycle 688 MW power station has one steam and two gas turbines. Its owner, Medway Power, is wholly owned by Scottish and Southern Energy plc.
The power plant automation architecture provides all the technical capabilities required and the display system provides a powerful and effective interface. It offers a great many ways of looking at the process: hierarchically structured process displays, data on the health of the automation processes and much more information. In addition, historical data gathered from the information management system is available to operators in the form of an online performance monitor and trend displays.
The tight integration of the operator systems with the control systems gives direct access to all information available anywhere in the control system. Operators can easily investigate every function quickly and in great detail thus reducing the time to track any problems in the plant.
The new display system was ordered, configured and thoroughly tested in just a few weeks. It was installed in just five days during the plant's two-week summer shutdown.
As part of the order Medway Power also ordered a new 'Composer' engineering tool from ABB. This software permits changes to be made to control strategy at site level even more quickly than before and provides highly efficient handling of document changes.
