CT514 – (GE) Mk-II Gas Turbine Controls

CT514 – (GE) Mk-II Gas Turbine Controls

5 days - 35 PDH Credits Awarded


No future dates scheduled


Learn the operations, maintenance and troubleshooting techniques on this control system in a classroom environment as opposed to 2pm Friday afternoon when the demand is high and the unit won't start.  Learn how to use all the OEM drawings that are provided with the machine, how to read the drawings, how to find information, how the various systems interact.  Learn how the Mk-II electronic control signals are developed, and how they result in positioning of the fuel control valve(s).  Learn how the control system responds to plant / system deviations to control load output.  Learn why and how temperature control circuits function to provide protection of gas turbine components.  Especially, the participant will learn outage preventive maintenance procedures that should be considered and how to troubleshoot problems.  This course is intended for E/I Technicians, Engineers and experienced Operators. This course continues to be offered once-per-year on our schedule, recognizing there are a few plants with these Mk-II systems still in service. Topical outline includes:  Review of Gas Turbine Theory, Equipment Overview, Auxiliary Systems, Electric Fundamentals as they apply to Mk-II Gas Turbine Controls, Control Elementary Aids, Control Panel Arrangement, Test Equipment, Power Supplies, Control Principles, Control Sequences, Start-Up, Speed Control, Temperature Control, Servo Valve Drive Systems, Protection Systems, Calibration and Troubleshooting.


Upon completion of this course personnel will be able to:
  1. Competently use the GE Mk-II drawings/schematics normally available on the job-site.
  2. Thoroughly understand the print and identification numbering system used throughout the turbine control system.
  3. Trace out the electrical signals throughout the control system.
  4. Understand the basic theory used with summing devices.
  5. Understand the hydraulic servomechanisms.
  6. Given a normal change in operating conditions, describe the proper response of the control system and the response of the individual components.
  7. Understand the appropriate calibration procedures.
  8. Understand troubleshooting sequences peculiar to this control system.
  9. Communicate control problems in a more effective manner.

What you will receive

  1. 1 copy of HPC Technical Services' textbook, (GE) Mk-II Gas Turbine Controls, a $195 value, as written by Harold Parker. It is a valuable desktop reference in addition to being able to enhance the learning process
  2. A Certificate of Completionwith 35 PDH.

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.
