PROJECT REVIEW

PROJECT TITLE:   DCS Enhancements Engineering Services (2004-current)

CLIENT:   Macquarie Generation - Liddell Power Station

PROJECT DESCRIPTION: The provision of engineering services to assist Liddell Power Station (4 x 500MW, coal fired, steam driven turbo-generators) with enhancements to their process control and Yokogawa CS3000 distributed control system (DCS). The DCS was installed in the early 2000's to replace Liddell's original relay and analog based controls. The engagement requires a broad range of skills and disciplines including investigation, reporting, concept design and implementation. These skills and disciplines underlie Provecta's extensive power station process control, instrumentation and electrical experience.

The multiple and diverse tasks undertaken as part of this engagement include;

• Design and implementation of a single button startup and shutdown sequence for the pulverised fuel and feedwater heater systems
• Miscellaneous process control anomaly reviews and rectification
• Additional plant integration into the DCS
• Alarm management and reduction
• Human Interface System (HIS) hardware upgrade specification and implementation
• Control system IT security reviews and implementation
• Electrical switchgear design
