Pitch-controlled system is the key link that ensures the wind-driven generator overall security, and wind-driven generator carries out power adjustments through the blade angle of regulating pitch-controlled system in the course of the work, makes engine output keep stable.
Referring to Fig. 1: the control loop power supply of existing wind-driven generator pitching system comprises the AC/DC power module; The input of AC/DC power module is passed through the given 230VAC of slip ring by the column foot ups power of wind-driven generator; The AC/DC power module changes 230VAC into 24VDC, and the output of AC/DC power module then is delivered to pitch-controlled system with 24VDC, in the AC/DC power module, is connected with the I/O end of PLC controller on the contact 13,14 of relay 1.1; The PLC controller is monitored the operating state of AC/DC power module with work; When UPS outage or AC/DC power module fault, the operating state of AC/DC power module occurs unusual, and the contact 13,14 of relay 1.1 is broken off; The PLC controller in time feeds back to the master control system of wind-driven generator with monitoring information, is shut down by master control system control pitch-controlled system.Yet; Because the control loop power supply of pitch-controlled system relies on unique ups power, does not have other stand-by power supply, in case the column foot ups power of wind-driven generator or slip ring and AC/DC power module break down; Pitch-controlled system is with ring current out of hand; At this moment the whole power down of control loop such as the controller of pitch-controlled system, servo-driver, super capacitor voltage monitoring module and other assist control relay, pitch-controlled system is in runaway condition, at the PLC controller after master control system feedback monitoring information; Master control system control pitch-controlled system emergency shutdown; The operation of this emergency shutdown causes serious impact, the safety of direct threats whole wind power generator to the main shaft brake of wind-driven generator, tower tube etc.
Summary of the invention
The objective of the invention is to: to the deficiency of above-mentioned prior art, a kind of reliable and stable wind-driven generator pitching system control power supply is provided, it has effectively improved the fail safe of wind-driven generator.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: a kind of wind-driven generator pitching system control power supply; Comprise the AC/DC power module; The input of said AC/DC power module is given by ups power; The alternating voltage that the AC/DC power module is given with ups power converts direct voltage to, on the AC/DC power module, is connected with the PLC controller of the operating state of AC/DC power module being monitored with doing, when the operating state of AC/DC power module is unusual; The PLC controller in time feeds back to the master control system of wind-driven generator with monitoring information, is shut down by master control system control pitch-controlled system; Said control power supply also comprises the DC/DC power module; The input of this DC/DC power module is given by the super capacitor of pitch-controlled system; The output of DC/DC power module selects circuit 2V1,2V2 to incorporate the output of AC/DC power module into through the diode height; All the time greater than the output voltage of DC/DC power module, the output voltage of the output voltage of DC/DC power module and AC/DC power module selects circuit 2V1,2V2 Gao Xuanhou to be delivered to pitch-controlled system through the diode height to the output voltage of AC/DC power module when "on" position.
The output voltage of said AC/DC power module is 25VDC.
The output voltage of said DC/DC power module is 24VDC.
The invention has the beneficial effects as follows: above-mentioned control power supply is on the basis of original current supply circuit, to have set up a current supply circuit by the given power supply of super capacitor; Make the two separate again in association; Forming Redundancy Design, guarantee that the control electricity consumption of wind-driven generator pitching system can stable supplying, is when the column foot ups power of wind-driven generator or slip ring and AC/DC power module break down; Pitch-controlled system also can reliability service; By the master control system of wind-driven generator control pitch-controlled system orderly closedown, avoid a series of negative consequences of bringing because of emergency shutdown, the fail safe that improves wind-driven generator.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further described.
Fig. 1 is the circuit diagram of existing wind-driven generator pitching system control power supply.
Fig. 2 is a kind of circuit diagram of the present invention.
Embodiment
Referring to Fig. 2: the present invention includes AC/DC power module and DC/DC power module.Wherein, The input of AC/DC power module is by the given 230VAC of ups power; The minus earth of AC/DC power module, the output of AC/DC power module is connected to pitch-controlled system, in the AC/DC power module, is connected with the I/O end of PLC controller on the contact 13,14 of relay 1.1; The PLC controller is monitored the operating state of AC/DC power module with work, and monitoring information is in time fed back to the master control system of wind-driven generator.The input of DC/DC power module is given by the super capacitor of pitch-controlled system; The minus earth of DC/DC power module; The output of DC/DC power module selects circuit to incorporate the output of AC/DC power module into through the diode height; This diode height selects circuit to be made up of diode 2V1 that plays the reverse blocking effect and diode 2V2, and diode 2V2 is located on the output cathode of AC/DC power module, and diode 2V1 is located on the output cathode of DC/DC power module.The output voltage of AC/DC power module when "on" position should be all the time greater than the output voltage of DC/DC power module.
