Including the rotary speed area between lower rotation speed limit, the rotating speed upper limit and the lower rotation speed limit and the rotating speed upper limit, by intrinsic frequency ftConversion
For rotating speed St, rotating speed StSize is located at lower rotation speed limit value SmWith rotating speed upper limit value SxBetween；
S2：When wind wheel, which turns frequency, is located at rotating speed resonance region, then the current state residing for Wind turbines, control wind wheel turn
Speed is rapidly rising or falling, and passes through rotating speed resonance region.
The operation principle of the present invention is to turn frequency in wind wheel a rotating speed resonance region is arranged with tower intrinsic frequency near intersections.
By the way that rational rotating speed resonance region bound is arranged and controls the running speeds of Wind turbines, making rotating speed, quickly drop is worn up or down
Rotating speed resonance region is crossed, avoids running of wind generating set in resonance region, tower resonance problem can be solved well.
For example, the intrinsic frequency of the tower of certain Wind turbines is 0.19Hz, corresponding wind speed round resonance region is 10rpm
~12rpm (wind speed is about 6m/s~7m/s)；When rotating speed is less than 10rpm (corresponding wind speed is in 4m/s~6m/s), Wind turbines
Slow-speed of revolution area is run on, the lower part of resonance region is located at.When rotating speed is more than 12rpm (corresponding wind speed is more than 7m/s), Wind turbines

It is drawn according to the history complete machine data of Wind turbines, and according to the rotating speed upper limit of rotating speed resonance region on rotary speed-torque curve
Corresponding upper limit torque and upper limit torque are drawn with lower rotation speed limit, corresponding torque is calculated according to power conservation.According to wind turbine
The complete machine characteristic of group draws basic rotational speed and torque curve, referring again to resonance zone, chooses lower limit rotating speed and maximum speed, and root
Corresponding torque is calculated according to power conservation.
Further, the drafting curve of rotary speed-torque follows power conservation principle.
The present invention can directly calculate torque by rotary speed-torque curve according to rotating speed, compared with the existing technology in
Look-up table, it can be ensured that running of wind generating set is in optimal power curve, therefore torque calculation is more accurate.
In the prior art, it in order to avoid tower caused by the active force between impeller and tower resonates, needs through torque control
Algorithm processed avoids the rotating speed of resonant frequency.The torque control algorithm generally used at present is that trap is added in speed closed loop control
Filter also has using in the corresponding wheel speed of resonant frequency is given, avoids the wheel speed given value at resonance point, this
Or a little control methods have larger impact to the load of wind turbine or cannot be quickly by resonant belts, finally all cannot be perfect
Solve the problems, such as that tower resonates.
And present invention can assure that Wind turbines stable operation outside resonance region, ensures machine when unit operation and resonance region
Group can pass through resonance region with fast and stable.It avoids unit residence time in resonance region long, effectively reduces tower fatigue
Load.
As shown in Fig. 2, for the rotary speed-torque curve of Wind turbines upwardly or downwardly crossing process, dotted portion is not wrap
The rotary speed-torque curve of the control method of evacuation containing resonance, i.e., in Sm~SxWithin the scope of corresponding resonance region, passed through by normal wind speed
The rotary speed-torque curve of resonance region；And bold portion is the rotary speed-torque curve for including resonance evacuation control method, i.e., in Sm
~SxWithin the scope of corresponding resonance region, rotating speed resonance region can be quickly passed through to avoid generating resonance with tower.
In order to accurately control the control method quickly passed through, the control method that control wind speed round is rapidly rising or falling
