Gas Turbine - 6,7,9, B,E, F, HA Class : Gas Turbine - Operation - F-Class (Advanced)

Course Description

This course is designed to enhance GE F-class gas turbine-generator operation skills and provides a detailed overview of F-class turbine operating sequences and control and protection functions. The course builds upon student's operational skills and develops a background in gas turbine-generator operation that enables participants to properly analyze operating problems and take the necessary corrective action.  Focus will be on the gas turbine and generator control and protection and does not include discussions on auxiliary support systems.

Participants may wish to bring their unit specific "Control Specification" with them to facilitate correlating classroom discussions with specific unit parameters.
