PURPOSE:To enable to perform the accurate drive of a generator by applying as a function of set rotating speed after the elapse of time when the set rotating speed value of the generator is set. CONSTITUTION:The rotating speed of a generator 1 is detected by a rotating speed detector 8, compared by a controller 6 with the output of a generator rotating speed setter 7, and a stationary drive unit 2 is controlled. In this case, the set value of the setter 7 is applied as a function f(t) rpm to become the rotating speed N rpm set after the determined time. Efficient drive is executed by selecting the function for minimizing the energy required for the drive. |
