Device processed adjusts proportional amplifier plate and adjusts in real time, and when Big Pinwheel F high speed rotations under the drive of wind-force, the first hydraulic pump P's I turns
Speed increases, and flow increases, and I rotating speeds of hydraulic motor M increase, and the incremental encoder mounted on I ends generator D detects generator
The rotating speed of D I has been more than rated speed, and has been detected by PLC controller, needs the rotating speed for reducing hydraulic motor M I, PLC controller
The discharge capacity of third hydraulic pump P III is reduced by proportional amplifier plate, flow system flow is reduced, makes the stabilization of speed of hydraulic motor M I.
When wind speed is too small, when Big Pinwheel F drives the first hydraulic pump I low-speed runnings of P, it is mounted on the incremental encoding of generator end at this time
Device will detect that I rotating speeds of generator D are less than rated speed, and PLC controller passes through for the rotating speed of stable hydraulic motor M I at this time
Proportional amplifier plate increases the discharge capacity of third hydraulic pump P III, increases flow system flow Q, the rotating speed of hydraulic motor M I is improved, to make hair
The rotating speed all-the-time stable of motor D I is near rated speed so that generator exports the alternating current of rated frequency.
