SYSTEM FOR CONTROLLING ANGULAR SPEED OF WIND POWER UNIT

摘要

The invention makes it possible to increase the reliability of the operation of a wind power unit under abnormal conditions. The system includes an angular wind speed sensor 3, first and second differential amplifiers 4, 7, a source of 6 master signal, switch 5, polarity switch 9, correction circuit 12, wind direction mismatch sensor 11 and wind wheel axis of rotation. When the wind speed and direction change, the aerodynamic orientation device 13 rotates and the signal magnitude changes at the output of the differential angular displacement transducer, the signal arrives at the second input of the differential amplifier 7, where the comparison with the specified signal takes place. In this case, the mismatch polarity relay is set to the state depending on the position of the rotary control element, and its executive circuit signal is fed to the control input of the polarity switch 9, which leads to the switching of its state. The driver of the rotation mechanism of the windwheel head enters the input 8 through direct and inverse signals, which eliminates the oscillations of the rotary head 2 and its turn in case of a sudden change in the direction of the wind. 1 hp f-ly, 2 ill.
