CT422 – Concepts Of Combustion Turbine Controls

CT422 – Concepts Of Combustion Turbine Controls

2 days - 14 PDH Credits Awarded



“Concepts of Combustion Turbine Controls" is a course designed to provide a working knowledge of combustion turbines and their associated control and protection equipment. Although not the focus of the course, attendees will gain a solid understanding of how power is generated.  Turbine controls system design concepts are the primary focus.  Included in these discussions are Start Up Sequencing, Speed/Load Control, Temperature Control, Emission Controls and CT Protection.  All discussions are conceptual.  It is our intention that the participant understand these topics well enough (conceptually) that they can be readily applied to any combustion turbine operating unit. Topical Outline includes:  Review of Combustion Turbine Fundamentals, Fuel Flow Considerations, Start Up Sequencing, Speed/Load Control, Temperature Control, Emissions, Protective Circuits. Recommended for Engineers and E&I Technicians.


Upon successful completion of this course the participant will be able to:
  1. Describe considerations for determining the combustion turbine start sequence.
  2. Describe how combustion turbine controls function off-line.
  3. Describe how combustion turbine controls function on-line and being responsive to grid conditions.
  4. Describe how combustion turbine controls function in temperature control.
  5. Describe emission concerns and differences in approach to minimize emissions.
  6. Describe considerations in determining fuel flow (demand for inlet valve positions).
  7. Describe operation of typical servomechanisms such as the Abex and Moog servo-valves.
  8. Describe typical operational exercises.
  9. Describe typical routine preventive maintenance activities.

Combustion TURBINE I&C and Field Engineering Maintenance CERTIFICATION

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.


All HPC instructors are educated ‘experts’ on the subjects they teach, with years of relevant hands-on experience (typically 20+ years), and have proven instructional skills. Brief resumes can be looked up on HPC’s website, www.TurbineGeneratorTraining.com.
