摘要
随着我国经济与社会的快速发展,电力工业的日益壮大,电力系统谐波已经成为电力领域日益重要的研究课题。谐波检测是解决其他谐波相关问题的基础和重要依据,因此进行谐波检测的研究具有重要的理论和实践意义。本设计以基2-FFT算法为基础,在以DSP芯片(TMS320F28335)为核心的控制器上实现256点F FT运算。系统硬件部分主要由电源转换电路、信号转换与调理电路、DSP控制器模块与液晶显示组成,实现对电网谐波的测量与显示。
With the rapid development of our economy and society and the fast growing of electric power industry,the harmonic of power system has become a research subject of electric ifeld which is becoming more and more important in our life.Harmonic detection is the foundation and the important basis to solve the problem of harmonic related to others,so the research on harmonic detection is of great theoretical and practical signiifcance.This design core algorithm is based on 2 FFT principle,using the DSP chip （TMS320F28335） as the control er to realize the 256 point FFT arithmetic.System hardware is mainly composed of power conversion circuit,signal transformation and conditioning circuit,DSP core control er and LCD, realize the power grid harmonic measurement and display.
