A gas turbine power plant can operate for years with little to no difficulty. Then, on that hot August day, when needed the most, it fails to start. We all know the drill! Or, perhaps, the unit does start, but the number of alarms are significant. How well personnel resolves this problem depends upon how well personnel (1) understand the “big picture” of how all the gas turbine component/systems relate, (2) how familiar personnel are with the print systems, and (3) the ability to interpret alarm information as applied to the available prints. This course targets the need for technicians/engineers to operate, maintain, calibrate and troubleshoot the Mk-IV control system. First, learn the big-picture. Next, learn how to maximize use of the OEM provided information to troubleshoot. Finally, take the information provided by the Mk-IV system and apply it.
includes: Mk-IV Hardware Familiarization, Operator Interface, Available Documentation, Reading Elementaries, FSR_SU/_ACC/_SD, FSRN, FSRT, Fuel Control and valve positioning, Water Injection, Variable Inlet Guide Vane, Protective Circuits
Upon completion of this course the participant should be able to:
- Demonstrate the ability to use OEM provided documentation that will include the Control Specifications, Elementaries, Application Manual, and P&IDs.
- Demonstrate the understanding of the Mk-IV 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 the elementaries.
- 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-IV 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 "4" circuits to trip/reset the machine.

Gas 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
