摘要
从满足电能质量测量的实时性要求出发,尽量减少数据的计算量,研究开发了基于复序列的FFT算法,该算法与FFT比较,分析同样序列长度的电压、电流数据,使其FFT运算量减少了一半.因此该算法在电能质量在线监测系统中得到了很好的应用.
In order to satisfy the real-time requirement of measurements of the power's quality and to reduce the amount of calculation to the best of the ability, the research of fast Fourier transform(EFT) based on complex sequence is carried out. Compared with the primary FFT, this algorithm only needs half of the amount of calculation when analyzing the same sequence length data of the voltage or the current. Therefore, this algorithm will apply well in the on-line monitoring system.
