Embodiment
Describe concrete structure of the present utility model in detail according to Fig. 1～3.Comprise be assembled in the cabin by yaw motor 3, speed reducer and be meshed with speed reducer actuation gear 2 be fixed on the deviation drive device that the driftage gearwheel 1 on the tower tube constitutes, driftage limit switch 6, driftage control cabinet 7, driftage PLC control unit 8, motor soft starter 9, yaw attitude sensor 10, be assembled in the component such as anemoscope 4, flow direction vane 5 of cabin top, and electric control loop.Wherein when reducing the power cable use amount, also alleviate the workload of wiring, four yaw motors 3 with power of deviation drive device are distributed on driftage gearwheel 1 top, and fix an independent driftage control cabinet 7 in the neutral position of four yaw motors 3.Exchanging the motor soft starter 9 that is provided with between 400V power supply and the yaw motor 3 by 8 activation of the driftage PLC control unit in the electric control loop.The analog signals that converts to through the sensor of anemoscope 4 and flow direction vane 5, real-time Transmission is given driftage PLC control unit 8, driftage PLC control unit 8 is gathered the pulse signal of yaw attitude sensor 10 simultaneously, and calculates the cabin angle with this, 3 operations of control yaw motor.
This wind power generating set independently go off course control gear control flow as shown in Figure 2: at first carry out initialization, utilize driftage PLC control unit 8 to carry out wind speed, wind direction collection then, convert the variation of nature wind speed, wind direction to 0 ~ 20mA analog signals by the sensor of the anemoscope 4 of nacelle top and the sensor of flow direction vane 5, and real-time Transmission is given driftage PLC control unit 8.Then according to the pulse signal of yaw attitude sensor 10, and calculate turning round of cabin with this and pull angle, and then judge: pull angle and then untie the mooring rope greater than 3 circles when turning round; Driftage PLC control unit 8 is definite according to the wind velocity signal of gathering, if greater than 3.5m/s, then starts automatically to the wind pattern; If apparent wind sends clockwise driftage order to greater than 8 ° behind the 120s that then delays time, if apparent wind to less than-8 °, the 120s that then delays time sends counterclockwise driftage order.Yaw motor 3 brakes discharge then, and the terminal A1 of motor soft starter 9 activates, and starts yaw motor 3.According to the calculating of driftage PLC control unit 8, when the driftage angle stops driftage during less than 2 °, brake motor driftage braking, driftage finishes.Whether driftage PLC control unit 8 monitoring driftage limit switches 6 activate, and guarantee that the cabin angle can not exceed safety range.
This wind power generating set control gear function of will going off course of independently going off course is peeled off from the blower fan master control system, thereby form independently yaw loop, electric control theory is as follows: the motor soft starter 9 that drags yaw motor 3 synchronously adopts the thyristor modulation module to form control circuit
Driftage PLC control unit is made up of cpu module (adopting Siemens S7-200 pattern piece in the present embodiment), IO unit module and two relay K 1, K2.
When needs started the windage yaw boat, traditional method was that main control PLC activates the driftage contactor, directly will exchange 400V and be added on the stator, and the rotating speed of yaw motor can reach rating value fast.The present embodiment has added a motor soft starter (MOD) between yaw motor 3 and interchange 400V power supply, as shown in Figure 3.Go off course clockwise when relay K 1 is closed, relay K 2 is gone off course when closed counterclockwise, i.e. relay K 1, relay K 2 control yaw motor 3(M1, M2, M3, M4) sense of rotation.Relay K 1 or relay K 2 adhesives, when driftage PLC control unit 8 activated the terminal A1 of motor soft starter 9, motor soft starter 9 began modulation, and yaw motor 3 voltage ramp rise, and yaw motor 3 speed increase gradually.When yaw motor 3 voltages reached AC400V, the thyristor modulation finished, the adhesive of bypass relay, and the operation of yaw motor 3 rated speeds, startup is finished.Driftage gearwheel on speed reducer actuation gear 2 and the tower tube 1 engagement at this moment drives cabin truss rotation, finishes driftage to wind.
Four tops that are distributed on driftage gearwheel 1 with power yaw motor 3 in the deviation drive device, motor soft starter 9 adopts one to drag four structures among Fig. 3, the startup that has guaranteed four motors reliably is consistent with the stopped process medium velocity, avoids laod unbalance to burn the motor phenomenon and takes place.
When the relative angle that detects cabin and wind direction when driftage PLC control unit 8 is spent less than 2, enter the driftage rest schedule: the terminal A1 that PLC control unit 8 controls of at first going off course output to motor soft starter 9 is a low level, the bypass relay of motor soft starter 9 disconnects, the thyristor modulation, yaw motor 3 terminal voltages, output speed reduce gradually, when speed is zero, and the braking of yaw motor 3 electromagnetic brakes, relay K 1, K2 disconnect simultaneously, and the driftage process finishes.
This wind power generating set control gear of independently going off course, when having reduced the driftage start and stop effectively to acutely rocking that each parts of unit cause; Simultaneously function independently distribution type control system guaranteed the reliable realization of driftage function to make unit be able to safe and reliable operation.
