This course presents the features of control and protection systems as used on gas turbine installations. It enables the participants to understand and be able to apply the following concepts: the function of the control system, the control loop, sensing devices, actuators, controllers, mechanical, electronic, digital, reliability i.e. redundant (duplicate) equipment, operator interface, display of information, inputting commands, controlling turbine output - FSR (Fuel Stroke Reference), automatic start-up sequence, permissive, speed sensors, switches, relays, modes of control, startup, speed/load, temperature, pre-set FSR, limitations, speed/load control, governor characteristic, loading rate limitations, automatic shut-down sequence, spin cooling, fired shut-down, exhaust temperature control, monitoring thermocouples, spread, monitoring combustion conditions, alarms and trips, flameout protection, over speed protection, over temperature protection, vibration protection.
By the end of this course delegates will be able to:
