摘要
为了准确地测量和分析电力系统中的谐波参数,在分析了常用的几种谐波测量方法的基础上,提出了一种基于FFT数字倍频整周期采样的电力系统谐波参数的测量方法.研制了以高性能ARM Context-M3内核的STM32微处理器为核心的电力系统谐波检测仪.检测仪具有测量基波和各次谐波的电压、电流绝对值的功能,并且能够测得谐波含有率、功率因数、功率和基波频率等其他参数,实现了对电力系统谐波参数的实时监控.
To measure and analyze power system harmonic parameters accurately,we analysed several methods of harmonic measurement and put forward a novel harmonic measurement method based on FFT and full period sampling of digital frequency.Finally,we developed a harmonic detector with the STM32 chip,which had high-performance ARM Context-M3 cores.It could measure the absolute values of fundamental and harmonic and could also detect the parameters of harmonic ratio,power factor,and power fundamental frequency.The harmonic detector realizes the real-time monitoring of the parameters of power system harmonics.
