The present invention the low wind speed activation system of hydraulic pressure wind power generator group from start to normal operation work during point
For following several stages：
First stage, oil-filled exhaust phase.It is preferred with reference to shown in Fig. 2, by first throttle valve 16 and second throttle 17
Amount of opening is adjusted to maximum, carries out short circuit to hydraulic pump 11 and hydraulic motor 12 respectively, while oil return control valve 24 is adjusted to logical
Line state carries out short circuit to oil return overflow valve 15.It throttles at this time in slippage pump 21, first throttle valve 16, high-pressure oil passage 13, second
A complete open-circuit hydrostatic system is formed between valve 17, low pressure oil way 14, oil return line 23, oil return control valve 24 and fuel tank 26
System.Then, start slippage pump 21 and export fluid, make fluid full of whole system and flow back into fuel tank 26, complete oil-filled row
Gas operates.
Second stage starts wind wheel and hydraulic pump and enters the low-speed running stage.With reference to shown in Fig. 2, first, by first segment
The amount of opening of stream valve 16 is adjusted to be 0, and the amount of opening of second throttle 17 is adjusted to maximum, at the same by oil return control valve 24 adjust to
Channel status carries out short circuit to oil return overflow valve 15.At this time in slippage pump 21, hydraulic pump 11, high-pressure oil passage 13, second throttle
17th, a complete open-loop hydraulic system is formed between low pressure oil way 14, oil return line 23, oil return control valve 24 and fuel tank 26.
Then, start slippage pump 21 and export high-voltage oil liquid, high-voltage oil liquid flows into hydraulic pump 11 and hydraulic pump 11 is pushed to drive wind wheel 3 simultaneously
It is rotated together, the fluid of outflow hydraulic pump 11 passes through high-pressure oil passage 13, second throttle 17, low pressure oil way 14 and oil return
Fuel tank 26 is flow back into after road 23 and oil return control valve 24.In this stage, hydraulic pump 11 is used as executive component, is exported in slippage pump 21
Resistance when wind wheel 3 and the startup of hydraulic pump 11 is overcome under the driving of fluid, so as to complete to start and wind wheel 3 is driven to enter the slow-speed of revolution
State.
Phase III, wind wheel and hydraulic pressure revolution speed improvement stage.Since 21 output flow of slippage pump is smaller, in 3 He of wind wheel
Hydraulic pump 11 completely start after, i.e., velocity sensor 19 to 11 Rotating speed measring stabilization of speed of hydraulic pump after, continue merely by mend
The flow that oil pump 21 exports is that the rotating speed of wind wheel 3 and hydraulic pump 11 further can not be promoted, and reaches and turns needed for its power generation
Speed, it is therefore desirable to further promotion be done to the rotating speed of wind wheel 3 and hydraulic pump 11 by extraneous wind energy.
With reference to shown in Fig. 2, maintaining, 17 maximum open amount of second throttle and 24 channel status of oil return control valve are constant
In the case of, slippage pump 21 is kept persistently to export fluid, and first throttle valve 16 is opened, in hydraulic pump 11 and first throttle valve
A local closed loop system is formed between 16.At this point, wind energy drives wind wheel 3 and slippage pump 21 drives hydraulic pump 11
Under collective effect, the promotion to 11 rotating speed of wind wheel 3 and hydraulic pump is realized.In the process, with the raising of 11 rotating speed of hydraulic pump,
The fluid part that hydraulic pump 11 exports flows back into fuel tank by second throttle 17 and oil return line 23, and another fluid then passes through
First throttle valve 16 directly flows back into the oil inlet position of hydraulic pump 11 and enters hydraulic pump 11, supplements due to 11 rotating speed of hydraulic pump
Promotion and to the demand of more fluid, so as to avoid at this stage hydraulic pump 11 occur being emptied problem, ensure the stabilization of system
Reliability service.
Major circulatory system is switched to closed-loop system by fourth stage by open cycle system.With reference to shown in Fig. 3, with 3 He of wind wheel
The continuous improvement of 11 rotating speed of hydraulic pump reaches the rotating speed that wind power generating set can generate electricity until when reaching optimum speed
It is required that when, oil return control valve 24 is switched into off state.At this point, oil return line 23 generates the back of the body under the action of oil return overflow valve 25
Pressure, so as to the oil inlet for making the fluid flowed into low pressure oil way 14 by second throttle 17 that check valve 15 be passed through to flow to hydraulic pump 11
Mouth position, forms a closed-loop system between hydraulic pump 11, high-pressure oil passage 13, second throttle 17 and low pressure oil way 14, from
And be that hydraulic pump 11 provides more fluid, meet the needs of its rotating speed further improves.
5th stage cut hydraulic pump in major circulatory system completely.At this point, the amount of opening to first throttle valve 16 carries out
It gradually turns down up to completely closing, so as to cut off the local closed loop system between hydraulic pump 11 and first throttle valve 16, makes hydraulic pressure
The fluid of 11 output of pump is all flowed by second throttle 17 in low pressure oil way 14, by the incision major cycle system completely of hydraulic pump 11
In system.
6th stage cut hydraulic motor in major circulatory system.Hydraulic pump 11 is completed to the complete of major circulatory system
After incision, after the pressure in system and the stabilization of speed of wind wheel 3, gradually the amount of opening of second throttle 17 is turned down, makes height
A part of fluid in pressure oil road 13 flows into hydraulic motor 12 and hydraulic motor 12 is driven to start to rotate, until second throttle 17
It completely closes, completes incision of the hydraulic motor 12 to major circulatory system.At this point, since the rotating speed of hydraulic pump 11 has reached normally
Generate electricity the rotating speed needed, therefore hydraulic motor 12 is directly entered working stage under the driving of hydraulic pump 11, drive generator 4 into
Row power generation.So far, the low wind speed startup to hydraulic pump 11 is completed, and entire hydraulic pressure wind power generator group is made steadily to smoothly enter
Normal operating condition.
In addition, during hydraulic pump 11 and hydraulic motor 12 are cut to major circulatory system, slippage pump 21 begins
Eventually in normal operating conditions, repairing operation is carried out to major circulatory system, ensures the normal operation of major circulatory system, avoids hydraulic pressure
Pump is emptied problem.Meanwhile the extra fluid that slippage pump 21 exports can directly flow back into fuel tank by repairing overflow valve 27
In 26.
