Power plant generators

  1. Jul 15, 2012 #1
    Do power plant generators regulate the output voltage the same way a car alternator regulates its output voltage. Or do power plant regulators control the output by regulating the rotation speed of the generator.

    yes, exactly same principle - vary the field to control voltage .
    Very small plants like windmills may use another method, so above is a generalization but a pretty true one and i think in the spirit of your question.

    Think about it for a minute - if the speed changed so would frequency.

    here's a more detailed one from Basler electric but you have to get there via Google.
    Basler is a very reputable manufacturer of these things.
