摘要
提出了基于现场可编程门阵列器件FPGA与数字信号处理器DSP并行结构的在线电能质量监测与分析。由FPGA同步产生系统控制时序,并充分利用FPGA与DSP各自在数字信号处理领域中的特点,在FP GA内设计了16位浮点FFT运算模块用于谐波分析,应用DSP实现电压波动与闪变等电能质量指标数据的计算,采用FPGA与DSP并行数据处理的方式,达到采样与数据处理的同步进行的目的,从而完成对多路信号的无缝采样与分析。
The implementation of online power quality monitoring system based on the parallel data processing structure of field programmable gate array (FPGA) and digital signal processor (DSP) is proposed. The signal time sequences of system are synchronously generated by FPGA. Considering the characteristics of FPGA and DSP in the digital signal processing applications, a 16 bit floating-point FFT module for harmonic analyzing is designed using FPGA, and computations for other power quality analysis such as voltage fluctuation and flicker measurement are performed by DSP. Based on the proposed structure, seamless sampling and data analysis of multi-input circuit can be achieved.
