G310 – Generators: Normal / Abnormal Operation

Description

There are NO SMALL PROBLEMS when it comes to your GENERATOR!!Learn how modern generators work on the power system grid.  Emphasis is placed on taking the magic out of generation operations as well as dealing with normal operations and those abnormal occurrences that could happen.  Attending personnel learn what really happens in the air gap.  An understanding of why and how the voltage / frequency varies is extremely important in being able to make the “best” operating decision.  The interesting part of operating a generator is that you do not know when this information is going to be needed, and when this understanding is required there will be no time to consult the book nor call the subject matter expert.  Learn what components are at risk and how.  At the course conclusion we will review 12+ abnormal conditions and for each we’ll discuss how the situation can develop, what are the symptoms, what protective relaying might exist, what are the proper actions, and if actions are not taken then what are the results.  Be prepared!  There are no small problems when it comes to your generator. Combustion Turbines, Diesels, Hydroelectric Turbines, or Steam Turbine Drives.  It makes no difference; we cover them all as it applies to safe and proper generator operation.  This course is intended for Control Room Operators, Shift Supervisors, Engineers, Technicians, and Operation Superintendents/Supervisors who operate these generating units. A topical outline includes: Generator Theory for Non-Engineers, System Operation, Generator Construction, Intro to Generator Controls, Generator Auxiliary Systems, Normal Operations, Abnormal Operations. Take a test now:
  1. Define a VAR.
  2. When opening the generator circuit breaker, under which conditions should the unit be in auto? And, under what conditions should the unit be in manual?  Why?
  3. Describe when motoring the generator a concern?
  4. What generator component is at risk if and when a negative sequence current event should occur? Why?
  5. Can a stator ground cause other damage on the generator?
How did you do?  With a little experience and this course you should have been able to answer each question in some degree of detail.

What you will receive

  1. 1 copy of HPC Technical Services' textbook, Generator: Normal/Abnormal Operations, a $149 value, as written by Harold Parker.

Frequently Asked Questions

  • Will HPC Technical Services bring this course to our location for our personnel only? YES, call or email Stephen Parker, Stephen@TurbineGeneratorTraining.com for a price quotation.
  • Will HPC Technical Services customize the presentation at our site to suit our particular needs?
  • Is HPC Technical Services' textbook available for purchase as a reference document?   $149 + S&H.
  • What is the cost for HPC Technical Service to deliver this course at our location? Well, of course that can vary, but generally speaking, if you're planning on having 6+ attend, when considering your T&L, it is to your advantage to perform the course at your plant (office).  You gain from the customization and price.
  • Is this course available for e-Training? Getting close.  Lecture one is currently available for on-line study and is recommended even if the stand-up lecture course is taken (since time is not a variable in e-Training).  Remaining chapters are currently under development.
  • Can HPC Technical Services provide troubleshooting "Technical Assistance" should the need occur? Yes we can.  Call or contact Stephen Parker, Stephen@TurbineGeneratorTraining.com for our rate sheets and any further information required.

Generator Operator Certification

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.
