A microprocessor control system (DCS) is used to control and monitor the performance throughout the plant.

A Bailey INFI90 DCS supports a decentralised hierarchical structure which allows for maximum mobility and flexibility to different plant locations. Thus control functions and data processing can be undertaking at the detailed plant area while at the same time retaining the ability to operate all control functions from the centre. It is sufficiently flexible to serve a wide range of requirements at loop and component level without any changes to hardware.

The DCS includes:

• The process control unit
• The data communication system
• The operator interface

A dedicated engineering workstation (EWS) provides for fast off-line development of control strategies.

The automation system design operates on a principle of high availability level.

The DCS which is in place ensures a safe, reliable, available, economical and simple operation of the boiler turbine generator units, together with their associated auxiliary plants.
