减小非同步采样误差措施的分析

Analysis on the Methods for Reducing the Asynchronous Sampling Error

谐波分析是电能质量评估的一个重要方面，由非同步采样导致的栅栏效应和泄漏误差一直是制约谐波分析精度的一个瓶颈。概述了减少非同步采样误差的措施和最新的一些研究成果，并对各种措施进行了分析和评述。最后对存在的问题和研究趋势提出了自己的看法。

Harmonic ware analysis is one of the important aspects for evaluating the quality of power supply. However, the barrier effect and leakage error resulted from asynchronous sampling are always the bottleneck of increasing the harmonic wave analysis accuracy.This paper summarizes and evaluates the methods for reducing the asynchronous sampling error and some latest research results.We also present our own opinion for the existing problems and researching trendin this area.
