Course Description                   

This course is designed to enhance GE E-Class (7EA and 9E) gas turbinegenerator operator knowledge and skills. The course provides a detailed overview of gas turbine operating sequences and control and protection functions. The course builds on prior knowledge and experience of the participants. They will learn to properly analyze operating problems of their gas turbine 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.This course will focus on the gas turbine and generator control and protection, the operational relationships of the compressor, combustion and turbine sections and generator systems. Discussion on turbine auxiliary systems is limited to key operational interfaces 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.Participants are also encouraged to bring information concerning issues their gas turbine may currently have or have experienced in the past, for discussion.
