Digicon Overview
The DIGICON Unit Control Panel (UCP) is a modular control system designed for Industrial Gas
Turbine and associated Plant control. The DIGICON system provides a wealth of standard
control and monitoring features which are easily and rapidly configured to provide a tailored Gas
Turbine control system.
The objective of the UCP system is to control the Plant equipment in a safe and efficient way.
This generally is carried out by two related processes:
• Plant Sequencing - This sequencing controls the operation of the Gas turbine governor by
determining, at any time, the type of governing control required
• Gas Turbine Governing Control - providing closed loop control of the gas generator, power
turbine and driven load in a stable manner.
In addition to these two main control processes, the UCP must ensure the safe operation of the
plant, by analysing the health of signals and plant processes.
Sophisticated, but easily configured features are provided within the UCP to allow
comprehensive Fault Monitoring and Failure Management to ensure the safe operation of the
total plant.
The system must also provide control, indication and annunciation of the operation and
condition of the plant. These Operator Interfaces are presented, either locally or remotely, via
computer based Colour Graphics stations and hardwired Operator panels.
