high voltage electric generation
High Voltage/ Electric generation
  • Electricity generation is the process of generating electrical power from other sources of primary energy.
  • Methods: Electromagnetic induction,

Electrochemistry (Battery), photoelectric effect.

  • Electromag. Inductions: Nuclear, hydroelectric, fossil fuels, wind.

Turbines: All turbines are driven by a fluid acting as an intermediate energy carrier. Many of the heat engines just mentioned are turbines. Other types of turbines can be driven by wind or falling water.

  • Turbines are usually driven by the following carriers:
    • Steam: Water is boiled by:
      • Nuclear fission, fossil fuels (Efficiency: %60).
    • Water, Wind.
  • Photovoltaic panels: convert sunlight directly to electricity (%40).
transmission and distribuiton
Transmission and Distribuiton
  • High voltage AC transmission (<500 kv)
    • Losses
  • Sub transmission lines (~ 70-150 kV)
    • Economical reasons (HV equipment are expensive)
  • User level transmission (~32-3.3 kV)
    • Safety
  • Why AC Transmission?
    • HVDC power production is expensive
    • The transformers enables simple voltage level conversion in AC
  • HVDC transmission
    • Low Loss, skin effect (AC)
    • Synchronization problem of AC transmission
    • Longer transmission lines
    • Less environmental problems
