CCGT power stations utilise direct gas turbine driven generators with recovery of exhaust heat used to raise steam for additional steam turbine energy recovery. As such CCGT power plants typically present high fuel energy conversion efficiencies in comparison to other thermal plant designs.

Industry/Application Description:

High availability Boiler/HRSG, Steam Turbine and Generator protection systems supplied by us for several customers with CCGT stations

These projects comprised:

• Pulse testable (for highest availability and lowest maintenance) hardwired safety system design
• SIL 2/3 capability (in low demand mode)
• Fail-safe protection on coolant, fuel oil & gas plant
• Extensive use of esoteric equipment for current
• transformer, phase imbalance/differential, reverse
• power, field excitation current etc.
• Complex sliding vacuum trip logic and boiler compensation analogue processing and analogue validation (comparison) to alarm on transducer failure
• HMI (Supervision) plant status graphics software

Key Business Benefits Derived:

• Ensures protection of very high value assets and power generation
• Ensures safety of personnel
• Enhanced system availability to avoid interruption of power generation (use of pulse testable platform) and to facilitate maintenance logistics
• Real time availability of process information
• Supports optimisation of production and electricity generation infrastructure
