CT516 - (GE) Mk-V Gas Turbine Controls

5 days - 3.2 Continuing Education Units Awarded

This Seminar targets the need for technicians/engineers to operate, maintain, calibrate and troubleshoot control systems such that availability and reliability can be maximized. This is accomplished by thoroughly understanding concepts of gas turbine control systems and how to use maintenance screens to quickly determine problems.

OBJECTIVES
Upon successful completion of this Seminar the participant should be able to:

1. Demonstrate the ability to use OEM provided documentation that will include the Control Specifications, Control Sequence Program, I/O Configuration, CSP Cross Reference, Alarm Drop List, Application Manual, and P&IDs.
2. Demonstrate the understanding of the Mk-V hardware components, how they are accessed, and how they communicate.
3. Demonstrate the ability to troubleshoot an equipment alarm, given an Alarm Drop Number.
4. Demonstrate the ability to interpret the more routine diagnostic alarms and recognize appropriate actions.
5. Demonstrate the ability to follow the major "control signal path" through a Control Sequence Program.
6. Demonstrate the ability to trace the derivation of a command signal to the servo-mechanisms.
7. Demonstrate the knowledge necessary to calibrate turbine valve mechanisms.
8. Demonstrate the ability (or knowledge -- based upon equipment availability) to more efficiently use the Mk-V <I> /<HMI> screens for evaluating/calibrating systems.
9. Demonstrate the ability (or knowledge -- based upon equipment availability) to force logic to facilitate calibration.
10. Given plant drawings, trace a signal to/from a field device through appropriate terminal boards, through circuit boards, to a digital "signal name".
11. Demonstrate the ability to follow signal flow to/from the <P> core to trip/reset the machine.
12. Describe differences between a <Q> trip and a <P> trip.
13. Demonstrate an understanding of on-line and off-line test sequences.
