摘要
为提高电网谐波分析的准确性和实时性,采用频率跟踪算法,无需加窗函数及校正措施,通过对采样点数的实时调整有效的减小了同步偏差,通过实验证明了使用该方法计算结果准确、可靠,在电力谐波检测与分析中具有较强的实用性。
In order to raise the accuracy and the real-time of the harmonic detection,the method of frequent tracking which need not window function and emendation means is used,and reduced the influence from the sampling error via adjusting the sampling points momentarily.The algorithm which is certified to be accurate and reliable by the experiment,has higher practicality in the harmonic detection and analysis.
