A graphical approach to hydrogenerator governor tuning

A graphical approach to hydrogenerator governor tuning is described. A graph which is developed can be used to predict optimum proportional and integral gains based on four parameters: the time constants of the water column and of the rotor inertia, and the self-regulation constants of the turbine and of the loading grid. The pole cancellation method of design is used, and the results are posed in an easy-to-use format that does not require the solution of systems of equations. Information on stability limits and comparisons with other work are included.<
