This course targets the need for technicians/engineers to operate, maintain, calibrate and troubleshoot control systems such that availability and reliability can be maximized. It has been HPC’s experience that when plant personnel have a control system problem and they seek help (for example, using HPC services) that the reason plant personnel had this problem troubleshooting was one of two explanations:
  1. Lack of understanding of the “big picture”, that is how the various control functions relate to one another.
  2. Lack of understanding of how to use the tools that are available to troubleshoot the problem.
The overall benefit of this course is that the participant will walk away with this knowledge. This is accomplished by thoroughly understanding concepts of steam turbine control systems and how to use maintenance screens to quickly determine problems.
We are reminded that the steam turbine is the important asset. The Mk-VIE control system is the human-machine-interface (HMI). This control system must be calibrated and maintained with the steam turbine-generator kept in mind. HPC approaches this course in this manner. As seen by the course objectives, particular attention is given to the development of control systems important to the operation of a steam turbine.

Topical Outline includes: Turbine Fundamentals, Turbine Control Concepts, Mk-VIE Fundamentals and Hardware, Software Installation, HMI Documentation, Mk-VIE Architecture, Blockware Concepts and Architecture, Blockware Functions, Introduction to the Toolbox Software, Speed/Load Control, Protection Systems, Alarm Troubleshooting, Valve Position Control & LVDT Calibration, Sequencing Editing Validation / Build / Download, Adding Analog I/O, Adding Contact I/O, Forcing Signals, Changing Control Constants, Data Historian, Trending, Trip History. For BWR participants we add Pressure and Bypass Valve Control I/O and Algorithms
 
WHAT YOU WILL RECEIVE:
  1. 1 copy of HPC Technical Services' textbook, (GE) Mk-VIE Steam Turbine Controls, drafted by Harold Parker.
  2. A "Certificate of Completion" with 2.9 CEUs, authorized for issue by the International Associate of Continuing Education/Training.  A “Certificate of Certified Completion”, including a signed letter describing accomplishments, with 5.3 CEU, provided participants complete an examination.
 
OBJECTIVES:
Upon successful completion of this Seminar the participant should be able to:
  1. Demonstrate an understanding of basic steam turbine operation.
  2. Demonstrate an understanding of the concepts of steam turbine controls.
  3. Demonstrate an understanding of the protective systems’ purpose, operation and test functions.
  4. Demonstrate the ability to use OEM provided documentation that will include the Control Specifications, Programming, I/O Configuration, Application Manual, and P&IDs.
  5. Demonstrate the understanding of the Mk-VIE hardware components, the component function, how they are accessed, and how they communicate.
  6. Demonstrate the ability to use “Toolbox” software.
  7. Demonstrate the ability to calculate a speed error using the “Toolbox” software.
  8. Demonstrate the ability to determine the load demand signal, using “Toolbox” software.
  9. Demonstrate the ability to determine a stop valve, control valve, intercept valve, extraction control valve (if applicable) and bypass valve (BWR participants only) controlling signal, using “Toolbox” software.
  10. Demonstrate the ability to troubleshoot an equipment alarm from the Mk-VI panel to the field device.
  11. Demonstrate the ability to interpret the more routine diagnostic alarms and recognize appropriate actions.
  12. Demonstrate the ability to trace the derivation of a command signal to the servomechanisms.
  13. Demonstrate the knowledge necessary to calibrate turbine valve mechanisms.
  14. Demonstrate the ability (or knowledge -- based upon equipment availability) to more efficiently use the Mk-VIE screens for evaluating/calibrating systems.
  15. Demonstrate the ability (or knowledge -- based upon equipment availability) to force logic to facilitate calibration.
  16. Describe how to change constants or re-program ladder logic such as to add contact input/outputs, add alarms, and/or alter sequencing.
  17. Given plant drawings, trace a signal to/from a field device through appropriate terminal boards, through circuit boards, to a digital "signal name".
  18. Demonstrate an understanding of how a trip signal is derived and applied.
  19. Demonstrate the ability to determine the pressure demand signal, using “Toolbox” software. (BWR participants only.)
 
STEAM TURBINE I&C CERTIFICATION:
There are two levels of certification (Both levels require this course):
  1. Engineer
  2. I&C Technician
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.)
