  • Hydroelectric development
    It is a propeller- type turbine with variable blade-pitch, the latter being controlled from the governor by means of a servo - motor and regulating valve mounted in the hub of the runner.
  • Low-head hydro-electric schemes
    The position of the blades is altered simultaneously with the opening of the guide vanes by the governor , working through oil servo - motors controlled by distributing valves which are actuated by the centrifugal governor itself.
  • Robust controller design for governing steam turbine power generators
    The governor is composed of a controller, servo motor and control valve (Fig. 2).
