Hydro-Electric Series

The objective of this course is to present and discuss the function and typical layout of the various auxiliary systems which are needed to support operation of the hydro turbine generator. Also demonstrated are the main features of auxiliary equipment that form the common elements of auxiliary systems.

After completion of this course, you should be able to understand and apply the following concepts:

• The function and application of different types of valves, including the gate valve, the globe valve, the control valve, the butterfly valve, the spherical ball valve, bypass valves, check valves, and the pressure relief valve
• The operation of vents and drains on piping systems and equipment
• The effect of water hammer
• The function and application of centrifugal pumps, both horizontal and vertical
• The function and application of positive displacement pumps, including the reciprocating pump, the screw type pump, and the gear pump
• The function and application of compressors, including compressor cooling and water extraction from compressed air
• Strainers and filters
• The importance of correct lubrication on all types of equipment
• Typical raw water and service water systems
• Features of cooling water systems
• De watering and drainage systems
• The supply of high-pressure water for fire protection systems, including sprinkler deluge systems
• Other fire protection systems, i.e. CO2 or Halon
• Compressed air systems, including service air, instrument air, high-pressure governor accumulator air, and blow down air for synchronous generator operation
• Oil storage and cleaning systems
• Ventilation systems for the powerhouse
