Description of the drawings
Fig. 1 is the structural schematic diagram of the system provided by the present invention for controlling current transformer of wind-driven generator device.
Specific implementation mode
Below in conjunction with the accompanying drawings and specific embodiment the present invention is described further, but following embodiments are absolutely not to this hair
It is bright to have any restrictions.
Embodiment 1：
A kind of system for controlling current transformer of wind-driven generator device, as shown in Figure 1, including main control module 1, data
Acquisition module 2, interchanger 3, several from controller 4, main execution module 5, from execution module 6；Wherein, main control module 1 with
It is identical from 2 structure of control module, include FPGA module, DSP module and the communication interface being connected with DSP module；Data are adopted
Collection module 2 is connected to the PFGA modules of main control module 1 by communication interface modules, and main execution module 5 is connected to master control molding
The DSP module of block 1；The FPGA module of main control module 1 is connected to interchanger 3 by the DSP module of main control module 1, exchanges
It is parallel arrangement of from controller 4 that the other end of machine 3 is connected with several；It is sent from the FPGA module desampler 3 of controller 4
Information, and the information of reception is sent to from the DSP module of controller 4 and is handled, will counted from the DSP module of controller 4
According to being sent to from execution module 6, main execution module 5 carries out power cell in the form of exporting PWM wave with from execution module 6
Control.
The communication interface being connected with DSP module includes USB interface, RJ45 interfaces, DB9 interfaces.
The data acquisition module 2 includes digital data acquisition module and analogue collection module.
The data acquisition module 2 is attached with main control module 1 by back panel connector.
The operation principle of system provided by the present invention for controlling current transformer of wind-driven generator device is as follows：
The system is powered on, system initialization, the program of FPGA module loads automatically；Data acquisition module 2 according to
The frequency 52k of setting carries out data sampling and conversion, and the FPGA module being uploaded in main control module 1, the FPGA module are pressed
DSP module Sampling interrupt is triggered according to the upload frequencies of DSP module write-in, is write data into the data buffer area of DSP module；
Obtained data are passed through Vector operation by DSP module, after data transformation and PI adjusting controls；Control command is exported to FPGA moulds
Block, FPGA module have detected data update, according to set frequency, are simultaneously sent to each from control module 4 or master control
Other boards of 1 internal system of molding block；If data are destined to from control module 4, receiving terminal is equally a FPGA mould
Block after the FPGA module receives data, is placed in order caching area, and the reception terminal being arranged according to DSP module, triggering
