It is a, and selected coil is made to be connected to electric system.
Hereinafter, being illustrated to the work of the power generator of thus configured first embodiment according to the present invention.
The energy of wind is for example converted to rotary force by rotating vane 10.In the case of the rotation of its rotary shaft, so that hydraulic pump
21,22 driving.Hydraulic pump works and working fluid is discharged, and from transport pipeline 50 to hydraulic motor 31,32 transmit workflow
Body and drive hydraulic motor.
By the rotation of hydraulic motor 31,32 come the rotor of rotary generator 40, and generator produces AC power.In liquid
The working fluid being discharged in pressure motor is recycled by return line 60 is sucked into hydraulic pump 21,22 again.In this way, rotating vane
10 rotary force is driven by hydraulic system, to be converted to electric power in generator.
According to the power generator of this first embodiment of the present invention, for example, the mean wind speed when set-up site maintains
When the 20% of desired output is below horizontal, by the coil of separated generator 40, so that first coil portion 43 and the second line
The coil ratio in circle portion 44 becomes 4:1, or divides the capacity for the hydraulic motor connecting with the rotor coaxial of the generator, so that the
The easy ratio of one hydraulic motor 31 and the second hydraulic motor 32 becomes 4:1, or the concentric rotation axis of segmentation and rotating vane 10
The capacity of the hydraulic pump of connection, by make the capacity of the first hydraulic pump 21 and the second hydraulic pump 22 than become 4:1 in a manner of carry out cloth
It sets.
When blowing in a manner of the 20% of insufficient desired output, only wound in the stator of generator 40 second
Coil part 44 maintains its operation.Also, when blowing in the way of 20% or more of desired output, so that in generator
Electric power is produced in the first coil portion 43 wound on stator.In particular, when sweeping blast, wound on the stator of generator
Electric power is produced together on one coil part and the second coil part.
If receiving the detection signal from airspeedometer 91 or hydraulic ga(u)ge and flowmeter or angular velocity of rotation detection meter,
Then operating specification of the controller 70 based on setting sends control signal to switch unit 45, according to the control signal, switch unit
Optionally switch generator 40 first coil portion 43 or the second coil part 44 and be connected to electric system, to fulfil steady

Therewith, when blowing in a manner of the 20% of insufficient desired output, so that working fluid is only small to capacity
The flowing of second hydraulic motor 32.Also, when blowing in the way of 20% or more of desired output so that working fluid to
Big the first hydraulic motor 31 flowing of capacity.In particular, working fluid is hydraulic to the first hydraulic motor and second when sweeping blast
The flowing of motor two sides.
If controller 70, which is received, detects meter from airspeedometer 91 or hydraulic ga(u)ge and flowmeter or angular velocity of rotation
Signal is detected, then operating specification of the controller based on setting, sends control signal to swash plate angle adjuster 80.According to the control
Signal, swash plate angle adjuster 80 can convert the angle of inclined plate to control the angular velocity of rotation of corresponding hydraulic motor 31,32.
In particular, if wind speed is reduced to the 20% of insufficient desired output, it can make working fluid should not be to the
One hydraulic motor 31 flowing, so that working fluid is flowed to the second hydraulic motor 32, thus with angular velocity of rotation appropriate progress
Rotation.If also, wind speed increases to 20% or more of desired output, and working fluid can be made hydraulic to second
Motor flow, so that the first hydraulic motor rotates.Especially, if sweeping blast, the first hydraulic motor and second can be made
Hydraulic motor all rotates, to be operated by desired output.
Equally, when blowing in a manner of the 20% of insufficient desired output, it can make working fluid only to capacity
Small the second hydraulic motor 32 flowing.Also, when blowing in the way of 20% or more of desired output, so that workflow
Body first hydraulic motor 31 flowing big to capacity.In particular, when sweeping blast, working fluid is to the first hydraulic motor and second
The flowing of hydraulic motor two sides.
If controller 70, which is received, detects meter from airspeedometer 91 or hydraulic ga(u)ge and flowmeter or angular velocity of rotation
Signal is detected, then operating specification of the controller based on setting, sends control signal to swash plate angle adjuster 80.According to the control
Signal, swash plate angle adjuster 80 can convert the angle of inclined plate to control the angular velocity of rotation of the hydraulic pump 21,22, to tie up
Hold tip speed ratio.
In the case that hydraulic pump 21,22 is fixed capacity type pump, controller 70 can be arranged to the drive shaft of hydraulic pump
Clutch or the pipeloop that is contacted with each hydraulic pump in the transmission control signal such as the valve arranged and select corresponding
Hydraulic pump and runner.
And, if wind speed is reduced to 20% level of insufficient desired output, it can make in this case
The discharge rate of first hydraulic pump 21 is zero, only properly adjusts the discharge rate of the second hydraulic pump 22.Working fluid can be from as a result,
Second hydraulic pump is flowed to the second hydraulic motor 32.
If also, wind speed increases to 20% or more of desired output, can make the discharge of the second hydraulic pump 22
Amount is zero, adjusts the discharge rate of the first hydraulic pump 21.Working fluid can be from the first hydraulic pump to the first hydraulic motor 31 as a result,
Flowing.
In particular, working fluid is discharged by two sides the first hydraulic pump 21 and the second hydraulic pump 22, connects if sweeping blast
, it can be flowed to the first hydraulic motor 31 and the second hydraulic motor 32.As a result, generator 40 with it is desired it is appropriate output extremely
Appropriate horizontal output operating, may finally make generating efficiency maximize.
Wherein, when being blown in mode more than desired output, open valve 52 can store in accumulator 51
Energy, at this point, can run supply pump 62 in order to supplement insufficient working fluid and supply working fluid from tank 61 to accumulator
To store energy.Later, when blowing in a manner of the 20% of insufficient desired output, the energy for discharging storage is sent out
Generated energy then can be improved in electricity.
Also, it when being blown with 20% level of insufficient desired output, and can be supplemented in accumulator 51
After working fluid, the energy of storage is discharged in the region of the low efficiency of generator to generate electricity, then can be mentioned from result
High generation efficiency.
For example, when being blown with about 10% level of rated output possessed by generator, what is illustrated in Fig. 1 is previous
In power generator, the efficiency of hydraulic pump and hydraulic motor is 32% respectively, and generator has 68% efficiency.
In the power generator of first embodiment according to the present invention, when with rated output possessed by generator 40 about
When 10% level is blown, the channel of working fluid is determined as from the second hydraulic pump 22 to the second hydraulic motor 32, and to generate electricity
Second coil part 44 of machine behaves.In this case, the efficiency of the second hydraulic pump and the second hydraulic motor is 72% respectively,
And the efficiency of generator is 87%.
In the power generator of first embodiment according to the present invention, when with rated output 20% possessed by generator 40 with
On mode when blowing, the channel of working fluid is determined as from the first hydraulic pump 21 to the first hydraulic motor 31, and to generate electricity
The first coil portion 43 of machine behaves, due to being carried out from this along the efficiency curve of hydraulic pump, hydraulic motor or generator,
Therefore high efficiency can be maintained to generate electricity.
On the other hand, in the case where being generated electricity using more than two rotating vanes, as shown in Fig. 2, with shared power generation
The mode of machine 40 is arranged also possible.
