Boundary Dam in Estevan Saskatchewan is just one of many plants where this Seminar has been successfully presented.

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 Seminar is intended for Control Room Operators, Shift Supervisors, Operations Superintendents, and Engineers.

TESTIMONIALS:

  • This Seminar will be useful for me because I will be moving up to Asst Unit Operator soon.
  • Hal Parker is a very knowledgeable and interesting trainer.  I really enjoyed this Seminar. Thanks.
  • I have a lot to learn and this Seminar helped to give me a good base of knowledge to build upon.
  • Have immediately applied the knowledge gained through attending this class.  Although the class was designed for general power producing process involving various types of turbo/generator sets and controls, there was more than enough information that pertained directly to the ABB turbines and generator employed at SEGS VI & VII.
  • This class exceeded my expectations, in almost all areas.
  • 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 abilty to encourage participants to beomce involved with the overall theme of the class, and the exchange of dialogue as to our specific areas of concern.

OBJECTIVES:

  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.
