Abstract
The utility model provides a safety guarantee system for a pitch control system, which comprises a pitch controller, a pitch control servo driver and a motor, wherein the pitch control servo driver is powered by an external power supply, the pitch controller is in electric signal connection with the pitch control servo driver via a control line, the pitch control servo driver is connected with the motor through a power loop under the control of the pitch controller, and the pitch control system is manipulated through the motor under the control of the pitch controller. The safety guarantee system also comprises a gyroscope inputting signals to the pitch controller and a storage battery or a super capacitor which directly provides power to the pitch controller, and/or provides power to the motor through a resistor or DC-AC (direct current-alternating current) converter controlled by the pitch controller. By improving the existing pitch control system in the two aspects, the reliable and correct operation of the pitch control system in an extreme case is ensured.
Description
Technical field
The utility model belongs to wind power generation field, is specifically related to the safe-guard system of existing pitch-variable system, to strengthen its fortune
Row reliability and adaptibility to response in emergency circumstances.
Background technique
Pitch-variable system is one of chief component of MW class wind turbine group (being called for short " blower fan "), also be to guarantee its reliable operation and the most important component of under extreme condition, surviving: when running into major accident such as high wind, parts damages and electric network fault when blower fan, as long as pitch-variable system still can proper functioning, just can avoid leaf destruction and crushing accident such as tower.So, guarantee that reliable, the true(-)running of pitch-variable system under limit case just becomes and be necessary very much.
The model utility content
The technical problem that the utility model solves is to provide a kind of safe-guard system of pitch-variable system, to guarantee reliable, the true(-)running of pitch-variable system under limit case.
A kind of safe-guard system of pitch-variable system, this system comprises change oar controller, becomes oar servomechanism, motor, become the oar servomechanism by external power source, becoming the oar controller is connected with change oar servomechanism electrical signal by guide line, described change oar servomechanism links to each other with motor by power loop under the control that becomes the oar controller, handles pitch-variable system by the control motor.
Further, this system also comprises and becomes the gyroscope of oar controller by the guide line input signal.Preferably, the said external power source voltage is 380V.
Further, this system also comprises storage battery or super capacitor, and described storage battery or super capacitor link to each other with change oar servomechanism by power loop, to becoming the power supply of oar servomechanism; Alternatively, described storage battery or super capacitor also can be powered to motor by the resistance or the straight-AC Transducer that are become the control of slurry controller; Perhaps this storage battery or super capacitor are directly powered to becoming the oar controller, and power to motor by resistance or straight-AC Transducer of being become the control of slurry controller.
The utility model has guaranteed reliable, true(-)running under its limit case by existing pitch-variable system is carried out the improvement of two aspects:
The first, gyroscope is installed in pitch-variable system, make pitch-variable system can obtain the axial fan hub rotating speed voluntarily, thereby can independently judge limit case: break away from dependence to the blower fan master control system, thus preferential, rapid, accurate and interference-free processing limit situation.
The second, by increasing storage battery or super capacitor and current supply circuit, make sum increase to three to the power loop that becomes the power supply of oar motor, making it power supply externally and become still can regular event under the situation that the oar servomechanism damages simultaneously.
Description of drawings
Fig. 1 is a super capacitor group condition monitoring system structure.
Embodiment
As Fig. 1, the safe-guard system of pitch-variable system comprises change oar controller, becomes oar servomechanism, motor, wherein become the oar servomechanism by outside 380 volts of power supplys power supply, becoming the oar controller is connected with change oar servomechanism electrical signal by guide line, described change oar servomechanism links to each other with motor by power loop under the control that becomes the oar controller, handles pitch-variable system by motor under the control that becomes the oar controller.This system also comprises to the gyroscope that becomes the oar controller input signal.This system also comprises storage battery or super capacitor, and this storage battery or super capacitor are directly powered to becoming the oar servomechanism, and/or powers to motor by resistance or straight-AC Transducer of being become the control of slurry controller.
