摘要 电力参数监测是电力系统中最基本的监测,对指导电力系统安全、经济和可靠运行起着关键的作用。对快速傅立叶变换(FFT)频谱分析的原理进行了详细地介绍,给出了FFT电网谐波分析过程,对交流电进行数据采样,将采样到的数据进行FFT变换,然后利用FFT计算的结果提取出来基波和谐波的信息计算谐波次数和谐波的有效值、谐波畸变率等参数。最后基于Mat lab编写谐波仿真分析程序验证了其结论。 The measurement of power parameters is one of the most basic measurements in power systems and plays a key role on running power systems in security, economy and reliability. FFT spectrum analysis method is described and the process of power harmonics analysis based on FFT is introduced. First to sample the alternating current, the sampling data are then changed with FFT, the calculations of the harmonic and harmonics valid values, and harmonic distortion rate for parameters are done by using the extracted information from FFT. Finally a harmonics analysis program based on Matlab verified the conclusion.
