$4,050 USD

Gas Turbine Advanced Operation 

 

Course Description                   

This course is designed to enhance GE F-class (7F, 9F, 6F) gas turbinegenerator configuration and operational knowledge and skills. The course builds on prior knowledge and experience of the participants. They will learn to analyze operating problems of their Gas Turbine properly and take the necessary corrective action. Participants gain competence to interpret fault annunciations and how to determine if the annunciated fault can be remedied by operator action or by the assistance of instrumentation and/or maintenance personnel. The F class Advanced Operations course will provide a detailed understanding of gas turbine operating sequences and control and protection functions by focusing on the operational relationships of the compressor, combustor and turbine sections along with generator and auxiliary systems. Discussion on turbine auxiliary systems is limited to key operational interfaces. Generator hydrogen and seal oil system operations will be covered. Participants may wish to bring their unit specific HMI control screens, alarm lists, control specification and device summary with them to facilitate correlating classroom discussions with specific unit parameters. Review of causes and responses for key process alarms and trips will be conducted throughout the course. Participants are also encouraged to bring information concerning issues their gas turbine generators may currently have or have experienced in the past, for discussion.
