CT516 – (GE) Mk-V Gas Turbine Controls

CT516 – (GE) Mk-V Gas Turbine Controls

5 days - 35 PDH Credits Awarded



This course 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.   We begin by studying Mk-V hardware; proceed to understanding Mk-V documentation, then the development of control signals.  Throughout the presentation, case studies are to enhance understanding of the concepts instructed.  On the GE Mk-V gas turbine controls we cannot emphasize enough, the importance of proper use of documentation.


Upon completion of this course the participant will 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 servomechanisms.
  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 knowledge (or ability -- 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.

Gas Turbine I&C Certification

There are two levels of certification (Both levels require this course):
  1. Engineer
  2. I&C Technician
Those who attend this course are automatically qualified to take HPC Technical Services' Certification Examination.  This examination is offered at no additional expense to the participant.  An 80% passing grade is required.  The examination length will not exceed 2-hours.  Those who complete this examination will receive a revised "certificate of completion" that recognizes this accomplishment along with two-copies of a "To Whom It May Concern" letter that states their accomplishment.  (Two copies are provided, one for the participants' employer and one for the participants' personal file.)   Consult HPC's website, www.TurbineGeneratorTraining.com, for detail on this certification program.
