Learn (or re-affirm) proper operation of the industrial steam turbine-generator from the perspective of the control room operators. Emphasis is on decision-making regarding safe and effective operation of industrial steam turbine generator equipment: TG Instruments / Controls, Starting and Loading Procedures/Considerations, and those Abnormal Events that occur all too often.  Equipment discussed is normally a function of the participants' background. Presentation includes industry events/case studies.  This course is intended for Control Room Operators, Shift Supervisors, Operations Superintendents, and Engineers.

Learn how a machine is at risk in service.  Learn what are the symptoms of abnormal conditions and what might be proper corrective actions.  Learn the purpose and function of the turbine-generator conrols, how they are properly operated, how the controls respond to system conditions and what is the type and purpose of various protective circuits.

Upon successful completion of this Seminar the participant should be able to:

  1. Participants will become familiar with those industrial turbine-generator components susceptible to damage in abnormal or fault like conditions, the type of damage that could occur, and what the operator can (or cannot) do to correct for the situation.
  2. Participants will be able to describe normal steam turbine-generator operating procedures as well as the more routine (using that word loosely) abnormal events.
  3. Participants will be able to draw a simple block - diagram that describes all the elements of steam turbine controls: speed, load, and extraction pressure control, the generation of a servomechanism signal, feedback and regulation.

  4. Participants will be able to draw a simple block-diagram that describes all the elements of a generator voltage regulator including the generation of excitation power, manual control, auto voltage regulation, anti-hunt devices, and limiters.
  5. Participants will be describe in detail the process of synchronizing, including discussion on the effects of synchronizing errors.

Seminar OUTLINE:

  1. Monday
    1. Steam Turbine Fundamental Review: Theory, Turbine Sections and Component Descriptions

    3. TSI Interpretations: Eccentricity (Overview, Component Description, Use of Instrument and Data Interpretation), Speed Detection, Valve Position, Vibration (including discussion of causes within a steam turbine) and Metal Temperatures
  2. Tuesday
    1. Turbine Controls for the Operators: Speed Control, Load Control, Extraction Pressure Control, Limiters, Flow Control, Overspeed and Reset System, Overspeed Trip
    2. Turbine Operations: Thermal Stress, Starting and Loading, Drains, Pre-warming Procedures, Normal Operations.
    3. Abnormal Conditions: Oil Whip, Packing Rubs, Mechanical Unbalance, Cracked Rotors, Low Speed Operation, Low Frequency Operation, Vacuum Breaking
  3. Wednesday

    2. Generator Construction: Stator Assembly, Rotor Assembly, and Exciters
    3. Excitation Systems: Introduction to Voltage Regulators, Transient Response of a Voltage Regulator, Stabilizing Circuits
  4. Thursday
    1. Generator Operations: Prior to Startup, Startup, Shutdown, Power Factor Adjustment, Abnormal Operations, Relationship Between Operation, Protection and Alarms, Alarms, Protection when Generator is Off-Line, Tripping Methods, Protective Actions for Generator
