This course targets the need for technicians/engineers to operate, maintain, calibrate and troubleshoot control systems such that availability and reliability can be maximized. This is accomplished by thoroughly understanding concepts of steam turbine control systems and how to use maintenance screens to quickly determine problems. HPC Technical Services’ staff experience is that all too often a lack of understanding of the ‘big picture’ leads to difficulties in troubleshooting operational problems. Secondly, the Mk-V maintenance screens leave much to be desired. Operations reports a ‘process alarm’. They provide you an ‘alarm drop’ number. Now what? How do you get from an alarm drop number to the I/O terminal point inside the Mk-V cabinet or at the source? All too often this simply takes too long when the goal is to get the machine started (or to keep it on). The difficulty is the ability to make use of the OEM supplied documentation. This course not only includes these two important skills but also provides a description of how the control signals are developed.
Mk-V Hardware Familiarization, Operator Interface, Use of Documentation, Big Block Language, Control Overview, Speed Control Algorithms, Load Control Algorithms, Pressure Control Algorithms, Flow Control Algorithms, Power Load Unbalance, Automatic Turbine Startup, Valve Position Demand, Hydraulic Systems, Protective Circuits, On-Line and Off-Line Tests, Calibration, and Editing.
Upon completion of this course the participant will be able to:
- Demonstrate the ability to use OEM provided documentation that will include the Control Specifications, Control Sequence Program, I/O Configuration, CSP Cross Reference, Alarm Drop List, Application Manual, and P&IDs.
- Demonstrate the understanding of the Mk-V hardware components, how they are accessed, and how they communicate.
- Demonstrate the ability to troubleshoot an equipment alarm, given an Alarm Drop Number.
- Demonstrate the ability to interpret the more routine diagnostic alarms and recognize appropriate actions.
- Demonstrate the ability to follow the major "control signal path" through a Control Sequence Program.
- Demonstrate the ability to trace the derivation of a command signal to the servomechanisms.
- Demonstrate the knowledge necessary to calibrate turbine valve mechanisms.
- Demonstrate the ability (or knowledge -- based upon equipment availability) to more efficiently use the Mk-V / screens for evaluating/calibrating systems.
- Demonstrate the ability (or knowledge -- based upon equipment availability) to force logic to facilitate calibration.
- Describe how to change constants or re-program ladder logic such as to add contact input/outputs, add alarms, and/or alter sequencing.
- Given plant drawings, trace a signal to/from a field device through appropriate terminal boards, through circuit boards, to a digital "signal name".
- Demonstrate the ability to follow signal flow to/from the core to trip/reset the machine.
- Describe differences between a <Q> trip and a <P> trip. Demonstrate an understanding of on-line and off-line test sequences.

- A Certificate of Completion with 35 PDH awarded.
Steam Turbine I&C Certification
There are two levels of certification (Both levels require this course):
- 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.) Consult HPC's website, www.TurbineGeneratorTraining.com, for detail on this certification program.
