|PREMIER POWER'S BALLYLUMFORD POWER STATION
Turbine Controls overhauled the central control room at Ballylumford Power Station. The project coincided with conversion of the plant furnaces from residual oil to gas burning. Outdated control consoles were unbolted from the control room floor and replaced with tailor made computer control system and ergonomically designed office furniture.
Console functions were replaced with screen based functions while mission critical equipment, such as emergency shutdown controls, was relocated in clearly visible and accessible positions. The system improves control of power output by turning large amounts of data into graphically presented information, enabling the operator to respond to the varying demands of Northern Ireland Electricity. Management by exception techniques are employed to provide the operator with only salient information.
The system is driven from the computer using a mouse to point and click on functions. It automates much of the logging the operator used to do. The reporting system is capable of being networked throughout the plant, providing the station manager with vital information. In an industry where availability, reliability and efficiency can effect profitability as seriously as fluctuations in the cost of raw materials, the efficient flow of information is no small concern. It is not only changes in the flow of electricity leaving the station that must be forecasted and measured.
Control of the fuel coming into the station is equally important. British Gas has to be advised how much fuel will be required at each period throughout the day. Any deviations have to be notified, and there is a scale of urgency with which notification must be made. The system at Ballylumford has been extended to include a powerful fuel gas monitoring system to meet this need, which enables forecasts and renominations to be made quickly and accurately.
