1. 引 言
Solving the problem of a harmonic sources localization means solving the problem of responsibility for a harmonic generation, what is very essential from the view-point of disputes between suppliers and customers regarding harmonic distortion. 解决谐波源定位的问题意味着解决谐波发生的责任问题，这从供电商和用户之间关于谐波失真的争论来看来看是非常重要的。There are many methods for localization of harmonic sources [1] - [10]. 谐波源的定位有好多方法[1－10].In the previous papers of the author the methods utilizing the specially-defined rates for a harmonic source localization have been proposed [9], [10]. 在作者以前的文章中，已经提出了利用专门为谐波源定位规定的比率（变化率）的方法[9],[10].The mentioned rates are the voltage rate and the current rate. The aim of the paper is to present comparison of the methods described in [9] and [10]. 所提到的这个比率就是电压比率和电流比率。本文的目的就是对文献[9]和文献[10]中描述的方法进行比较。The comparison of these methods is made from the view-point of their theoretical background (the considered criteria of a harmonic source localization), principles of localization of harmonic sources, utilization, efficiency and case studies. 这些方法的比较是从它们的理论背景（所考虑的谐波源定位的准则）、谐波源定位的原理、利用、效率和案例研究出发而进行
