The present invention can effectively improve the flexibility of Wind turbines, extends the life-span of unit；The present invention uses the wind energy conversion system of pulp distance varying mechanism that impeller weight can be made to alleviate, and makes the force-bearing situation of complete machine be greatly improved, and makes Wind turbines likely remain optimal conversion efficiency under different wind speed, makes output maximum, thus improve systematic function.
Feather speed governing is one of main mode of speed regulation of modern wind electromotor.Arrangements for speed regulation reduce owing to wind speed increases the trend making wheel speed accelerate by the way of increasing propeller pitch angle.When wind speed increases, feather hydraulic cylinder action, promote blade to rotate the wind energy making blade absorb to the direction that propeller pitch angle increases and reduce, maintain wind wheel to operate in nominal speed range.When wind speed reduces, carry out inverse operation, it is achieved the power that wind wheel absorbs can be held essentially constant.Hydraulic control system has the advantages such as driving torque is big, lightweight, rigidity big, registration, hydraulic actuating mechanism rapid dynamic response speed, it is possible to ensure more quickly and accurately blade adjustments to predetermined pitch.The variable pitch device of the large-scale wind driven generator of domestic production at present and operation uses hydraulic system as dynamical system mostly.
Before electromotor is connected to the grid, is carried out variable pitch control by speed control according to the speed feedback signal of electromotor, determines that blade is in standby or feather position according to rotating speed and wind velocity signal；After electromotor is connected to the grid, power controller works, and power governor generally uses PI control, and power error signal obtains propeller pitch angle position after PI computing.
When wind-driven generator is in stopped status, propeller pitch angle is in 90 firm positions, and at this moment air-flow does not produce torque to blade；When wind energy conversion system is become running status from stopped status, propeller pitch angle firm is reduced to standby angle (in native system be 15 firm) with certain speed (about 1 firm/s) by 90；If wind speed reaches grid-connected wind speed, propeller pitch angle continues to be reduced to 3 firm (propeller pitch angle has optimal wind energy absorptance when 3 firm left and right)；After electromotor is connected to the grid, when wind speed is less than rated wind speed, propeller pitch angle is made to be maintained at 3 firm constant；When wind speed is higher than rated wind speed, according to power feedback signal, controller, to the voltage of proportioning valve output-10 ~+10V, controls direction and the size of proportioning valve output flow.The propeller pitch angle of blade is handled in the flow of feather hydraulic cylinder valve in proportion output and direction, makes output maintain near rated power.If breaking down or when having halt command, controller will export rapid feathering order so that wind-force function quick shutdown, feathering speed is firm up to 20/and s.
