TG307 – Steam Turbine Generator Controls For Operators

TG307 – Steam Turbine Generator Controls For Operators

4.5 days - 32 PDH Credits Awarded



Learn (or re-affirm) proper operation of the steam turbine-generator from the perspective of the control room operators. Emphasis is on decision-making regarding safe and effective operation of steam turbine generator equipment: TG Instruments / Controls, Starting and Loading Procedures/Considerations, and those Abnormal Events that occur all too often.  Equipment discussed is normally a function of the participants' background. Presentation includes industry events/case studies.  This course is intended for Control Room Operators, Shift Supervisors, Operations Superintendents, and Engineers. Learn how a machine is at risk in service.  Learn what are the symptoms of abnormal conditions and what might be proper corrective actions.  Learn the purpose and function of the turbine-generator controls, how they are properly operated, how the controls respond to system conditions and what is the type and purpose of various protective circuits. "I found the class to be immensely helpful and informative as it pertains to my job function and responsibilities.  The instructor was enthusiastic, and very helpful with questions and concerns of those participating in the class.  Especially helpful with generator operation and protective systems.  I enjoyed the instructor's effort and ability to encourage participants to become involved with the overall theme of the class, and the exchange of dialogue as to our specific areas of concern." --- KJC Operations, Kramer Junction, CA


  1. Participants will become familiar with those turbine-generator components susceptible to damage in abnormal or fault like conditions, the type of damage that could occur, and what the operator can (or cannot) do to correct for the situation.
  2. Participants will be able to draw a simple block - diagram that describes all the elements of steam turbine controls: speed, load, and pressure control, the generation of a servomechanism signal, feedback and regulation.
  3. Participants will be able to draw a simple block-diagram that describes all the elements of a generator voltage regulator including the generation of excitation power, manual control, auto voltage regulation, anti-hunt devices, and limiters.
  4. Participants will be describe in detail the process of synchronizing, including discussion on the effects of synchronizing errors.
  5. Participants will be able to describe normal steam turbine-generator operating procedures as well as the more routine (using that word loosely) abnormal events.
