vST327 – Steam Turbine Operation Practices & Alarm Response

5 days (4-hours sessions) - 20 PDH Credits Awarded



This course targets traditional fossil / nuclear steam turbine operations.

When things go wrong, with respect to steam turbine operations, they go wrong quickly!

  • Packing rubs can occur for what might appear to be, no apparent reason. Your gut reaction on what to do, when a packing rub occurs, can be seriously wrong!  Learn the concepts here and be prepared.
  • One moment all is fine, and the next moment the alarms are dancing off the wall (or CRT). Could it be a water induction incident?  The next few minutes of decision making and operator action is critical!  Learn how the turbine is impacted and what one should or should not do.
  • We often hear that there are two lines of defense against overspeed. Learn, exactly what they are and what they are not!
  • Haven’t seen that vibration trend before. What does it mean?  Learn what data needs to be collected to answer this question and how to come to an answer as well.
  • The lube oil temperature is 110oF while on turning gear. So what?  Learn why this can be an issue.
  • ….. and the list of issues go on.

This course is intended to have a positive impact upon steam turbine operator decision-making.  The course specifically targets Control Room Operators, wannabe CRO, and Shift Supervisors.  Engineers can benefit as well.  It has been HPC’s experience that all too often that the procedures for starting up and loading a steam turbine are based upon hand-me-down communications.  Too often, equipment has been improved but procedures have not.  Too often, equipment has been replaced, but the procedures have not been altered.  This course is not intended to develop or discuss procedures, but is, instead, directed toward development, in the operational personnel, a thorough “understanding” of what considerations the ideal procedures are based upon.  HPC believes that if personnel thoroughly understand the operating concepts the result will be less forced outages, improved efficiency and improved availability.

Emphasis is on those steam turbines driving large generators.  HPC’s “Steam Turbine Operating Practices & Alarm Response” course is instructed by experienced OEM engineers.

An approximate topical outline is as follows:


1 hour      Introduction

1-hours    FATT and Thermal Stress

2-hour     Turbine Supervisory Instrumentation


2-hours    Steam Turbine Control Concepts

1-hour     Pre-Warming

1-hour     Startup


4-hours    Load Change Considerations, and Normal Shutdowns.


4-hours    Abnormal Operation is to include:  Eccentricity Issues, Packing Rubs, Effect of Synchronizing Errors, Lube Oil Problems during Startup, Water Induction (an in-depth discussion), Overspeed (Normal, Emergency and Destructive)


3 hours    Vibration Trends as a Telltale of Operational Problems, Differential Expansion Issues, Effects of Frequency Deviation, Vacuum Breaking, High Exhaust Hood Temperatures, Over Pressure/Temperature at Inlet, and Feedwater Heater Removal.

1 hour      Course Conclusion

What you will receive

  1. One copy of HPC Technical Services' textbook, Steam Turbine Operation Practices & Alarm Response, a $249 value, as written by Harold Parker.  The textbook will be sent to the registered personnel approximately 2-weeks prior to course date.  Recognize that registration needs to be more than 2-weeks prior to scheduled course date to ensure the text will arrive prior to course date.
  2. A Certificate of Completion with 17.5 PDH awarded will be emailed to the participant in a pdf format. 


Upon completion of this course the participants will be able to:

  1. Describe those steam turbine components that are susceptible to damage in abnormal operating conditions.
  2. Describe performance issues that may develop relevant to the condition of the turbine steam path.
  3. List and describe those actions that can be taken by operations to minimize efficiency losses.
  4. List those turbine supervisory instruments typically found on a steam turbine application and describe the intended function of each instrument.
  5. Draw a simple block - diagram that describes all the elements of steam turbine controls: speed, load, and pressure control, the generation of a servomechanism signal, feedback and regulation.
  6. Describe the function of each of the block diagram elements drawn.
  7. Describe normal steam turbine start-up and shutdown procedures.
  8. Describe each of those operating parameters monitored by turbine supervisory instruments, instrument function, and interpretation: eccentricity, shell expansion, differential expansion, vibration, axial position, temperatures.
  9. Demonstrate understanding of the risk / benefits associated with the defeat of any OEM recommended trip.
  10. List abnormal conditions often experienced in operating steam turbines, and for each abnormal condition discussed:
    1. Describe any operational symptoms.
    2. Describe how the steam turbine is at risk.
    3. Describe typical controls’ automatic response.
    4. Describe required (recommended) operator response.
  11. Describe protection of the steam turbine from system related events: stability issues, loss of synchronism, synchronizing errors, motoring, power / load unbalance, overspeed.
  12. List those common tests performed on steam turbines and for each item listed explain the purpose of the test and important procedural items relevant to that test.
