摘 要: 随着DSP在数字化处理和数字控制系统领域日渐成为一项成熟的技术,一种基于DSP的快速傅立叶变换(FFT)的实现方法被提出。该算法采用汇编语言实现,并采用目前控制领域最高性能的处理器TMS320F281x系列DSP对采样信号进行FFT运算,能快速检测出电网中三相电压、电流的各次谐波,以进行谐波的实时分析处理。通过实验和现场运行,验证了算法的正确性和高速性,可作为一种通用的算法应用于谐波检测。 DSP is developing into a mature technology in digital process and digital control, based on which a method of Fast Fourier Transform Algorithm (FFY) is proposed. The algorithm is achieved by assembly language, using the most high-powered processor-TMS320F281x DSP in current control field to carry through the FFT operation of sampling signal, and it can detect all harmonic waves of three-phase voltage and three-phase current in grid, so we can do the harmonic analysis duly. Through the experiment and field work, the precision and high-speed of the algorithm are verified, therefore it can be used as a universal algorithm in harmonic detection.
