摘要
本文介绍了一种基于全波傅立叶的智能变电站谐波分析方法。该方法首先对智能变电站中合并单元输出的IEC61850-9-2数据进行解析,再采用全波傅立叶算法开展谐波分析。文中对该方法的效果进行分析,结果表明采用该方法可以准确计算出基波及各次谐波分量的幅值和相位。
In the paper,a smart substation harmonic analysis method based on full-cycle Fourier algorithm is introduced.The method principle is that the IEC61850-9-2 message outputted by merge unit in smart substation is analyzed firstly,and then harmonic is analyzed by using full-cycle Fourier algorithm.The method effect is also analyzed,the analysis results show that the amplitude and phase of fundamental wave and harmonic components can be calculated exactly by using the method.
