TG201 – Steam Turbine Generator Fundamentals

TG201 – Steam Turbine Generator Fundamentals

3 days - 21 PDH Credits Awarded



This course has been designed for individuals who are new to steam turbine-generator operations and maintenance. It also provides an excellent review for individuals who have been involved with steam turbine-generators, but have not received formal training.  In this course we discuss the basic theory of operation and apply that theory to a discussion of components that immediately follows.  If one is to operate, maintain, or manage steam turbine generator functions then one needs to know why is works as it does, what are some of the design differences, and what is the significance of the various components.  Nozzles, blades, shells, rotors, valves; all are covered as to their function.  On the generator; frame, core, armature windings, rotor, field windings, exciter: all are covered as to their fundamental function. Topical Outline includes: Steam Turbine Operating Principles, Component Descriptions, Steam Valves, Unit Descriptions, Intro to Operations, Turbine Auxiliary Systems, Generator Operating Principles, Generator Component Descriptions, and Generator Auxiliary Systems. HPC’s instructional staff on this topic is significant.  The materials were developed by those who have been working on steam turbine-generators their whole career.


At the completion of this course the participant will be able to:
  1. Describe the function of turbine nozzles.
  2. Describe the function of turbine blades/buckets.
  3. Describe the energy conversions that take place in impulse and reaction turbines and identify where the conversions occur.
  4. Describe the function of various steam turbine components.
  5. Describe the areas where the turbine is sealed and why.
  6. Explain how the turbine expands and why it is important.
  7. Explain the function of the various steam valves.
  8. Describe full arc and partial arc operation.
  9. Trace the flowpath for steam turbine auxiliary systems.
  10. Describe the major components of the steam turbine auxiliary systems.
  11. Describe the component parts of the generator.
  12. Describe the three circuits that are basic to the AC generator operation.
  13. Describe the major components of the generator auxiliary systems.
  14. Trace a flow path through the generator auxiliary systems.
