Abstract
The intelligent stepless speed stabilizer for wind driven generator includes stepless speed varying mechanism with connected power transmitting input shaft and output shaft, and features that the input shaft or the output shaft is provided with rotation speed sensor, the rotation speed sensor is connected via A/D converter to monolithic computer, and the monolithic computer sends out speed varying command based on preset program and parameters to the executor of the stepless speed varying mechanism. By means of the equipment of the present invention, the wind driven generator can output stable rotation speed via automatic regulation in condition of varying wind force.
Description
Technical field
The present invention relates to wind-driven generator, particularly a kind of intelligent stepless speed stabilizer for wind power generation device.
Background technique
Along with the development of society and the raising of people's living standard, the demand of the energy is presented growing trend inevitably.In fact, the situation of power cuts to limit consumption has appearred in China recent years, illustrates that power supply is very nervous.Utilize water generating, resource-constrained; Utilize coal and oil or combustion gas to carry out thermal power generation, the non-renewable chemical industry energy substance of not only a large amount of consumption, and can cause environmental pollution.Therefore, seek clear energy sources,, have good prospect really as exploitation wind energy, solar energy or the like.In the prior art, though human have long term studies for wind energy development, invention and on some local use wind generating unit, still, wind generating unit of the prior art, metastable input speed of fitness for purpose, and wind-force changes often, the time low, suddenly big or suddenly small when high, also have wind direction to change, in fact a stable rotating speed can not be arranged by the direct-connected alternator shaft of wind wheel.Therefore, need utilize stepless speed changing mechanism.Though various stepless speed changing mechanisms are arranged in the prior art, as mechanical stepless speed-changing device, automatic stepless speed variator etc. all just have the function that realizes stepless speed regulation between input shaft and output shaft.Obviously, can't be applicable to wind-driven generator if it is not carried out intelligent the improvement.
Summary of the invention
The present invention is directed to the defective or the deficiency that exist in the prior art, a kind of intelligent stepless speed stabilizer for wind power generation device is provided, adopt this device under the situation that wind-force changes,, to make device output meet the stable rotating speed of electricity generating device requirement by automatic adjusting.
Technical conceive of the present invention is, in the passing shaft lower end of wind-driven generator one stepless speed changing mechanism is installed, and under the situation that wind-force changes, by automatic adjusting, makes device output meet the stable rotating speed of electricity generating device requirement.Automatically regulate and finish by intelligent control system.
Technological scheme of the present invention is as follows:
The intelligent stepless speed stabilizer for wind power generation device, comprise the stepless speed changing mechanism that is connected with transmission of power input shaft and output shaft, it is characterized in that: described input shaft or output shaft are provided with speed probe, this speed probe connects single-chip microcomputer by analog-digital converter, and this single-chip microcomputer sends speed change according to pre-set programs and parameter and executes instruction to the actuating device of described stepless speed changing mechanism.
Described single-chip microcomputer is the MCS51 single-chip microcomputer, HOLTEK single-chip microcomputer, PIC single-chip microcomputer, ATMEL single-chip microcomputer, PHILIPS single-chip microcomputer, WINBOND single-chip microcomputer or MOTOROLA single-chip microcomputer.
Described speed probe is torque rotary speed sensor or digital torque rotary speed sensor.
Beneficial effect of the present invention is as follows:
Because wind-power electricity generation stepless speed stabilizer device of the present invention, adopted intelligent control system, promptly input shaft or output shaft are provided with speed probe, this speed probe connects single-chip microcomputer by analog-digital converter, this single-chip microcomputer sends speed change according to pre-set programs and parameter and executes instruction to the actuating device of described stepless speed changing mechanism, thereby can under the situation that wind-force changes,, make device output meet the stable rotating speed of electricity generating device requirement by automatic adjusting.
Embodiment
Below the present invention is described in further detail.
The mechanical transmission of the present invention on wind-power electricity generation adopts stepless speed changes devices.Metastable input speed of motor fitness for purpose, the present invention installs a stepless speed changes devices in the passing shaft lower end, under the situation that wind-force changes, by automatic adjusting, makes device output meet the stable rotating speed of motor requirement.Automatically regulate and finish by intelligent control system.Intelligent control system comprises speed probe, data processing system, single-chip microcomputer, the instruction executing device that is installed on the passing shaft.Sensor converts the passing shaft change in rotational speed of experiencing electrical signal to and passes to data processing system, digital processing unit becomes the electrical signal conversion that receives digital signal and passes to single-chip microcomputer, single-chip microcomputer carries out datumization with the digital signal that receives according to the program of setting and handles and send the speed change execution command, actuating device changes the speed change execution command into carries out action, thereby finishes speed-change process.
Single-chip microcomputer can be selected the MCS51 single-chip microcomputer for use, HOLTEK single-chip microcomputer, PIC single-chip microcomputer, ATMEL single-chip microcomputer, PHILIPS single-chip microcomputer, WINBOND single-chip microcomputer and MOTOROLA single-chip microcomputer.Speed probe can be selected torque rotary speed sensor for use, both can obtain torque data, can obtain rotary speed data again.And can directly adopt digital torque rotary speed sensor, it is output as the digital signal of frequency quantity, so this sensor can be easily and computer or interface microcontroller.
Should be pointed out that the above embodiment can make those skilled in the art more fully understand the present invention, but do not limit the present invention in any way.Therefore, although this specification has been described in detail the present invention with reference to drawings and Examples,, it will be appreciated by those skilled in the art that still and can make amendment or be equal to replacement the present invention; And all do not break away from the technological scheme and the improvement thereof of the spirit and scope of the present invention, and it all should be encompassed in the middle of the protection domain of patent of the present invention.
