The invention relates to an independent
feathering control system and a control method for a
wind driven generating set, wherein the
control system comprises a sampling module, a control module and a driving module. A
feathering motor in the driving module is connected with the blades of the
wind driven generating set through a speed
reducer. The sampling module is used to acquire the signals such as the
wind driven generating set power, the boss rotating speed, the
impeller position, the
feathering angle, the
paddle vibration, and the like, and to respectively send the acquired signals to the control module. The control module comprises a wind
machine power controller for
processing the wind driven generating set power
signal and the boss rotating speed
signal, a periodic unbalanced load compensation controller for
processing the
impeller position
signal, the wind
machine power signal and the boss rotating speed signal, a
transient state impact load compensation controller for
processing the feathering angle signal, the
paddle vibration signal, the
impeller position signal, the wind
machine power signal and the boss rotating speed signal, and an
output coupler for processing the signals outputted from the three controllers and comprehensively outputting the signals to the driving module.
