Combined Cycle Operations
This course is designed as a familiarization course to increase understanding of the combined cycle process for power generation. During the training, trainees will startup and shutdown the simulated unit in an integrated manner and to be exposed to simple and complex unit malfunctions in the control room and in the field. Course objectives are as follows:
- Introduce trainees to plant systems and major components and how they dynamically interact
- Familiarize trainees with the Human Machine Interface (HMI) and plant control and how safe and efficient operation of the unit can be affected by plant problems
- Provide the trainees with hands-on operating experiences in plant operations using the HMI.
- Increase trainee understanding of plant equipment and control processes and integrated operations of the plant
Trainees will spend 40% of the time in the classroom and 60% of the time interacting with the Combined Cycle simulator.
Recommended participants: Engineers, operations personnel, and managers from electric utilities, engineering & construction firms, and equipment vendors with interest in combined cycle plants.
