摘要
本文针对风力发电系统设计了一种基于DSPTMS320F2812的数据采集系统,采用芯片内部ADC模块进行采样,并设计了信号调理电路保护ADC模块。针对风力发电系统谐波电流的特点,利用MATLABFDAtool滤波器设计分析工具,设计了FIR滤波器。最后在CCS环境下编写程序实现了数据采集和数字滤波。
This paper gave a design of a data acquisition system based on DSP TMS320F2812 for wind power generation system. Use the chip’s ADC module to sample data and design a signal conditioning circuit to protect the ADC module. Since the wind power generation system always contains harmonic current, take account of its characteristic, designed a FIR filter to filter out these harmonic current by use of the MATLAB FDAtool. Finally, implement the data sampling and digital FIR filter under CCS programming environment.
