<p>PURPOSE:To start and apply a water wheel generator stably in a short time. CONSTITUTION:The controller for a water wheel generator comprises a deviation calculator 4 for taking a difference between a frequency of the generator to be obtained through a detector 1 and its set value, and a PWM(pulse width modulation) signal generator 5 for outputting a pulse width signal responsive to the deviation to raise/lower the frequency of the generator, thereby controlling the generator to be controlled to be started up to a desired set value stably in a short time. A switch 6 is closed only at the time of starting, opened at the time of uniform speed to be switched to a control of an automatic uniform speed unit 7.</p> |
