Control component in one, connected between each middle control component by CAN bus communication modes, variable pitch driver and pitch drive motor it
Between be equipped with detection module, detection module includes current transformer and voltage transformer.
Preferably, being equipped with a backup power supply module in the variable pitch driver, backup power supply module includes electric power storage
Pond.
Preferably, the middle control component can be PLC.
Preferably, the cabinet body periphery of control cabinet and pitch drive cabinet is coated with anti-decaying paint in the variable pitch.
Preferably, three variable pitch drivers in the pitch drive cabinet are equidistantly arranged side by side.
Three three motor wind-power paddle changing devices of drive mainly increase by two drivers compared to single drive on variable pitch cabinet, every drive
Dynamic device has original driver whole work functions (i.e. every driver can work independently), once certain driver
Failure can be selected either automatically or manually and be switched to newly-increased spare drive.It can be shut out with the task of mean allocation driver
Exhausted driver overload fault and cause to shut down.Increased two drivers can also be respectively used to spare and program pilot, new increment
Outer function can be modified when perhaps modifying relative program in program pilot or spare drive, and not influencing blower normally makes
With.
Three drive three motor wind-power paddle changing devices compared to a driver is increased on double drive variable pitch cabinets, increase a drive newly
Dynamic device is used as standby and has the whole work functions of double drives.Once switching can be selected either automatically or manually in certain driver malfunction
To newly-increased spare drive, blower stable operation is ensured.
A kind of as described above three drive the control system of three motor wind-power paddle changing devices, comprising the following steps:
Step 1: detection wind speed and direction detects the wind speed and direction around blade by wind direction and wind velocity sensor, passes
It is defeated by variable pitch and controls cabinet；
Step 2: control pitch drive cabinet detects paddle after control cabinet calculates wind direction and wind velocity data in variable pitch
The angle of leaf sends commands to the variable pitch driver inside pitch drive cabinet, then adjusts blade by variable pitch driver control motor
Angle, meanwhile, angle is to variable pitch driver after blade feedback regulation；
Step 3: power generation is adjusted: being controlled cabinet in variable pitch and is sent commands to frequency converter, the torque that frequency converter sets generator carries out
Power generation, meanwhile, the revolving speed of generator feedback at this time is to frequency converter；
It in step 2, is connected between each middle control component by CAN bus communication modes, then each middle control component is equipped with one
Host, other are slave, after the host breaks down, toward one address of pusher, and using control component in this as host,
He is slave.
Preferably, operating current and work of the detection module to corresponding motor in step 2, in variable pitch driver
Voltage is monitored in real time, while the job information of the variable pitch driver is transferred in other by CAN bus communication modes and is controlled
Component；It is detected using electric current of the current transformer in detection module to driver, voltage transformer examines voltage
It surveys, voltage, current data is transferred to DSP data processing module, data are analyzed, by the middle control component hair as host
Switching command out, to guarantee that variable pitch driver normally switches.
The beneficial effects of the present invention are: joined three in the three three motor wind-power paddle changing devices of drive and its control system
Variable pitch driver improves the stability and reliability of pitch-controlled system operation, greatly reduces O&M cost；Moreover, in variable pitch
It drives in cabinet, is connected between each middle control component by CAN bus communication modes, by way of independently selecting host, effectively shut out
When host breaks down absolutely, the case where system operation fault, the reliability of system is improved.
