This Seminar 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. Lake of understanding of how to use the tools that are available to troubleshoot the problem.
The overall benefit of this Seminar 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-VI 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 Seminar in this manner. As seen by the Seminar objectives, particular attention is given to the development of control systems important to the operation of a steam turbine.
Upon successful completion of this Seminar the participant should be able to:
  1. Demonstrate an understanding of the concepts of steam turbine controls.
  2. Demonstrate the ability to use OEM provided documentation that will include the Control Specifications, Programming, I/O Configuration, Application Manual, and P&IDs.
  3. Demonstrate the understanding of the Mk-VI hardware components, the component function, how they are accessed, and how they communicate.
  4. Demonstrate the ability to use “Toolbox” software.
  5. Demonstrate the ability to trace steam turbine specific control signals, using the “Toolbox” software.
  6. Demonstrate the ability to troubleshoot an equipment alarm from the Mk-VI panel to the field device.
  7. Demonstrate the ability to interpret the more routine diagnostic alarms and recognize appropriate actions.
  8. Demonstrate the ability to trace the derivation of a command signal to the servomechanisms.
  9. Demonstrate the knowledge necessary to calibrate turbine valve mechanisms.
  10. Demonstrate the ability (or knowledge -- based upon equipment availability) to more efficiently use the Mk-VI screens for evaluating/calibrating systems.
  11. Demonstrate the ability (or knowledge -- based upon equipment availability) to force logic to facilitate calibration.
  12. Describe how to change constants or re-program ladder logic such as to add contact input/outputs, add alarms, and/or alter sequencing.
  13. Given plant drawings, trace a signal to/from a field device through appropriate terminal boards, through circuit boards, to a digital "signal name".
  14. Demonstrate an understanding of how a trip signal is derived and applied.
  15. Demonstrate an understanding of the protective systems’ purpose, operation and test functions.
  16. Demonstrate knowledge necessary to implement OEM recommended on-line and off-line tests.
