Control systems in large combined cycle power stations

The concept of a centralised control room is readily accepted as an essential requirement for running modern power plant. The operator is provided with all the necessary plant information and controls to run the station from a logically laid out desk. Modern control schemes offer flexible control and automation along with the ability to handle and present large amounts of information within very short response times. However, all systems have their limitations and care must still be taken when applying such technology. The GEC ALSTHOM group has built up the necessary expertise over many years, both on high reliability design and project management of large turn key power plant projects. This ensures a totally integrated power plant package is provided. Mainly using the example of GEC ALSTHOM's standard Vega 209f design the author explains the philosophy used in selecting control and instrumentation for a large combined cycle power plant.<>
