This paper describes the design and dynamic behaviour analysis of the mechanical governor system applied to the WINDMEL, a variable-speed wind turbine generator with a 15-meter rotor. The centrifugal forces of the governor weights and the spring forces will automatically regulate the blade pitch angle, performing the rotor speed control and the generator power control without the need for any other auxiliary power source for pitch control. Analytical results and observed data proved that the mechanical governor system works effectively in an actual wind turbine generator which continuously suffers from varying wind.
