Abstract
A method and apparatus for governing a generator which generator comprises micro-hydropower generating equipment usable in run-of-the-stream situations. A plurality of dump loads are associated with the electrical output of the generator and changes in frequency of the output phase voltage of the generator are detected. The dump loads are switched into or out of association with the generator in response to the frequency changes so as to cause substantially compensating frequency changes. The rate at which the compensating frequency changes occurs are damped desirably by use of a flywheel.
