Combined Cycle Power Plant Operation (Plant Shutdown)

Course Description

This course will cover the procedures for shutting down the CCGT. The participants will learn and practice on the simulator how to shutdown the unit, to either hot stand-by condition, or full shutdown drained condition. Emphasis is on the gradual unit deloading and safe diverting of the steam to ensure that the stress limits of the combined cycle main equipment and pipe work are not exceeded. The active and reactive unit unloading is matched to ensure generator stability. Opening of drain and vent valves in the correct sequence for complete condensate drainage and proper preservation of the plant are also covered.

Course Topics

Topics that are covered in the course are:

• CCGT Safe Shutdown Practice and Preservation Principles
• CCGT Shutdown to Hot Standby Condition
  • Unit load reduction
  • Generator circuit breaker opening
  • Startup of turning gear
  • Heat Recovery Steam Generator (HRSG) box up for hot standby
  • Diverting steam from the steam turbine
  • Steam turbine shut down and drains opening
• CCGT Shutdown to Cold Condition
  • Unit load reduction
  • Generator circuit breaker opening
  • Startup of turning gear
  • Diverting steam from the steam turbine
  • Steam turbine shut down and drains opening
  • HRSG cool down
  • HRSG shutdown
  • Auxiliary Steam shutdown

Combined Cycle Power Plant Problems & Troubleshooting

Course Description

This course provides participants with practical hands-on training in dealing with a selection of typical plant problems that occur in real-life combined cycle power plants. The training is conducted using advanced real-time simulators that simulate the problems in a realistic environment for the participants to understand, analyse, troubleshoot and respond to the problems.

The cause and the effects of the each abnormal event are explained and discussed in detail during the course. The associated alarms, the actions that are to be taken by the operator from the time the alarms initiate, the methodology used to find out the cause of the abnormality and the actions to be taken to restore the plant to normal condition will be demonstrated and explained.

At the end of the course, the participants will be individually evaluated on his ability to deal with plant abnormalities - in terms of how he recognizes and reacts to alarms, investigates the cause of the alarm, and the actions taken to restore the plant to its normal condition or to ensure the safe shutdown of the plant.

Course Topics

Topics that are covered in the course are:

• Types of Abnormal Situations and Emergencies
• Alarms and Alarm List
