CT201 – Combined Cycle Turbine-Generator Fundamentals

CT201 – Combined Cycle Turbine-Generator Fundamentals

4 days - 28 PDH Credits Awarded



Reliability and availability of combined cycle power plants can be a matter of skilled routine operations and maintenance activities. These skilled routine operations and maintenance personnel begin their quest with a thorough understanding of combined cycle fundamentals. Understanding of the interaction of major components is required. Furthermore, understanding the operating needs of the individual components may be crucial to satisfactory operation of the machine. Topical Outline includes: Thermodynamic principles as they apply to a combustion turbine, Descriptions of types of combustion turbines, Application, Major Gas Path Components, Major Auxiliary Systems, Starting Systems, Combustion Turbine Controls Overview, Generator Principles of Operation, Generator Components, Thermodynamic principles expanded to apply to a combined cycle plant, HRSG, Steam Turbine Fundamentals, and the Condenser. This course is intended for individuals who are new to combined cycle operation for power generation. It also provides an excellent refresher for persons that have been involved with combined cycle equipment and generators, but have not received any formal training.


At the completion of this course the participant will be able to:
  1. Describe the thermodynamic principles associated with the combustion turbine.
  2. Describe the basic cycles used for different types of combustion engines.
  3. List the major components of any combustion turbine and describe their function.
  4. Discuss the various ways in which efficiency of a combustion turbine can be changed.
  5. Describe the flow through the combustion turbine including any extraction points.
  6. Identify and state the function of a given CT auxiliary system and describe its operation.
  7. Describe the effects that humidity, ambient temperature, compressor ratio, firing temperature, exhaust temperature, and exhaust pressure have on combustion turbine performance.
  8. Describe the ability to determine combustion turbine output and heat rate.
  9. Describe those thermodynamic principles associated with a combined cycle power plant.
  10. Describe the construction and operation of Steam Turbines.
  11. Describe the function of Heat Recovery Steam Generators.
  12. Describe the construction and operation of Generators.
  13. Describe the major systems associated with Gas (Combustion) Turbine, Steam Turbines and Generators.
  14. Describe the sequencing that occurs in a normal startup, synchronization and operation.
  15. Describe the different fuel systems and requirements for operation.
  16. Describe the function of the Condensate System

Gas Turbine Certification

There are three levels of certification (All three levels require this course):
  1. Field Engineer
  2. Combined Cycle Maintenance Mechanic
  3. Auxiliary 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.
