CT401 – Principles of Gas Turbine Performance

CT401 – Principles of Gas Turbine Performance

2 days - 14 PDH Credits Awarded



This 2-day course is designed to familiarize plant personnel with those design and operating parameters that effect gas turbine performance.  In order to accomplish this we need a good understanding of basic theory, then we need to understand what components effect performance and why.  3rd, personnel need to understand how various plant designs can affect unit performance (again we need to why).   Finally, personnel need to understand how operating practices effects unit performance.  Once all this information is assembled in a logical manner, HPC’s instructor will discuss how this material can be applied in a way to make a positive impact upon the gas turbines’ operational availability and performance. For plant engineers, this course is the first step toward the development and/or implementation of an effective heat rate (performance) improvement program.   For operational personnel, this course identifies those operating practices that effect unit performance, that is, how do operating decisions impact performance.  Design and operating theories of gas turbines are presented. Thermodynamics and heat transfer are reviewed and applied (in a practical way) to operation.  Calculations are performed, using actual test data, to determine gas turbine efficiency and corrections. A topical outline includes:  Thermodynamic Cycles for Gas Turbines, Component Construction, Operation and Maintenance Considerations, ASME Performance Test Codes Applicable to Gas Turbines, Combustion Turbine Performanceissues, and Efficiency Monitoring Programs. This 2-day class is the front end of a 4.5 day class, Principles of Combined Cycle Performance, CT402.


At the successful completion of this seminar the attendee will be able to:
  1. Describe the thermodynamic principles that apply to a gas turbine power plant.
  2. List the operational / performance factors that impact the gas turbine performance.
  3. Describe the level of testing and monitoring that is typically required to determine unit performance.
  4. List those major steps required to perform 3 major component performance tests.
  5. Demonstrate the ability to analyze plant performance data to determine where component efficiency has deteriorated
  6. Determine realistic heat rate improvement goals
  7. Develop corrective action plans to achieve the established heat rate performance goals.
  8. List the types of measuring equipment and perform the calculations required to analyze plant performance.

Gas Turbine Operator Certification

There are two levels of certification (Both levels require this course):
  1. Engineer
  2. Control Room Operator
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.
