CT327 – Frame 7EA / 7FA Gas Turbine Operations And Alarm Response

4.5 days - 32 PDH Credits Awarded

$2,895.00

Description

This course is intended to have a positive impact upon gas turbine operator decision-making. The course specifically targets Control Room Operators, wannabe CRO, and Shift Supervisors. Engineers will benefit as well. Normal operations are discussed to include startup, on-line operations, and shutdown. Alarm conditions are discussed with the following items in mind: implications of the alarm occurrence (why/how is the unit at risk), probable causes, and actions to be taken. There are significant differences between the 7EA and 7FA as well as significant similarities. Each topic will be discussed starting with an overview of the component / system. Where there are significant differences then both the 7EA and 7FA will be discussed. When this course is taught on-site the emphasis will be on that unit located at that site.

Objectives

Upon completion of this course, the participant will be able to:
  1. Describe the relationship of the various turbine components and how they may be at risk during operations.
  2. Describe the different fuel systems used in gas turbine operations.
  3. For each of the gas turbine auxiliary systems describe the systems' purpose, function of major components making up the system, normal operations, and abnormal conditions.
    1. Inlet and Exhaust Air
    2. Cooling and Sealing Air
    3. Lube Oil System
    4. Hydraulics
    5. Trip System
    6. Fuel Gas
    7. Liquid Fuel
    8. Fire Protection
    9. Water Wash
    10. Cooling Water
    11. Starting Means
  4. Given a gas turbine control system block diagram, sequence the turbine through start-up preparation, a start up, load changes, normal shutdown, and emergency conditions.
  5. Demonstrate the ability to navigate the operating screens to sufficiently to trace an alarm drop.
  6. Given an alarm, describe how the unit may be at risk.
  7. Given an alarm, describe what are the most proper actions to take (short- and long-term).

Gas Turbine 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.
