  • Induction generator

    Induction generators are useful in applications such as mini hydro power plants, wind turbines, or in reducing high-pressure gas streams to lower pressure, because they can recover energy with relatively simple controls An induction generator usually draws its excitation power from an electrical gr...

  • Generator

    These generators are packaged with an engine or turbine to be used as a motor-generator set and used in applications like naval, oil and gas extraction, mining machinery, wind power plants etc Advantages of AC Generator: These Generators are generally maintenance free, because of absence of brush Easily step up and step down through ....

  • Voith | Excitation

    Typically, the power source for the rectifier bridge is derived from the generator stator itself, also known as self-excited State-of-the-art power electronics combined with a self-excited configuration, enhance the reliability of the static excitation system as its power part is independent from the rest of the power plant...

  • Electric Machines

    The field excitation power needed for these huge machines can be as much as 25% of the output power ( 25 KW in a 10 MW generator) though this reduces as the efficiency improves with size so that a 500 MW generator needs 25 MW (05%) of excitation power If the field voltage is 1000 Volts, the required field current will be 2500 Amps...

  • Excitation (magnetic)

    Except for permanent magnet generators, a generator produces output voltage proportional to the magnetic field, which is proportional to the excitation current; if there is no excitation current there is no voltage A small amount of power supplied as field current may thus control a large amount of generated power and can be used to modulate it...
