Steam Turbine control systems supported by a 3D Animated Program there will be many power point presentations. With the help of extensive graphics and animation which will provide a virtual exposure on Large Steam Turbines and Governors and other control systems.
Who should take this course
Operators especially Maintenance Engineers, Supervisors, Superintendents.
Part 1 - Control Systems:
- The Function of the Governors
- Understanding the full function of Governors
- The speed of driven equipment must be controlled
- Understanding when an increased load of the turbine slows the turbine what happens to the flyballs
- What happens when friction in the mechanism what takes place.
- Operating Principles.
- Overview of CBT 3D Video of Steam Turbine Governors
Part 2 - Steam Turbine Unit Controls:
The main functions of modern steam turbine control systems are as follows we will note their functions:
- Speed and acceleration control during start up.
- Initialization of generator excitation Synchronization and application of load in response to local area generation dispatch commands.
- Pressure control various forms inlet extraction back pressure etc
- This control mode is initial pressure control.
- When a steam turbine is supplied by a heat recovery boiler the amount of steam generated can vary independently.
- Initial pressure governing allows the steam turbine to draw all the available steam out of the header while maintaining constant pressure.
- Unloading and securing of the turbine.
- Protection against serious hazards i.e. loss of lube oil pressure high exhaust temperature high bearing vibration
- A single failure in the controls will not cause a shutdown. It will cause a diagnostic alarm and is repairable on-line.
Part 3 - Understanding HAZOP/HAZID:
- Every operator needs to know how to carry out a HAZOP Analysis Participants will be given the opportunity to conduct a HAZOP Analysis.
- This will be followed by a question paper on Governors & Governor systems including other control systems.
- Comprehensive Manual Power Point Presentations Self-Assessment questions (answers will be provided at end of the session)
