A method of controlling the torque of a small hydroelectric generator in response to fluctuations in the inflow rate without system frequency synchronization step-out.

摘要

The present invention enables small-scale hydroelectric power generation in response to fluctuations in the inflow rate without system frequency synchronization out-of-step without causing a step-out phenomenon even if the inflow rate changes. TECHNICAL FIELD The present invention relates to an apparatus and method for controlling torque of a machine, an encoder provided on a rotating shaft of a generator that is rotated by a water turbine to sense the number of rotations of the rotating shaft of the generator, and a generator detected by the encoder. Control means for controlling the generator torque according to the rotational speed, but controlling the drive torque in proportion to the sensed rotational speed, and the drive torque is set according to the torque supplied by the average inflow flow rate The generated generator is controlled, but a change in the rotational speed of the rotating shaft of the generator due to a change in the actual inflow flow rate is detected to detect a change in the inflow flow rate, and the detected rotational speed of the rotating shaft is handled. By adjusting the driving torque of the generator, the inflow rate is changed, characterized in that as continue to be operated without the generator stops. [Selection] Figure 4
