摘要：A harmonic source diagnostic analytic is vital to identify the root causes and type of harmonic
source in power system. This paper introduces a verification of periodogram technique to diagnose
harmonic sources by using logistic regression classifier. A periodogram gives a correct and accurate
classification of harmonic signals. Signature recognition pattern is used to distinguish the harmonic
sources accurately by obtaining the distribution of harmonic and interharmonic components and the
harmonic contribution changes. This is achieved by using the significant signature recognition of harmonic
producing load obtained from the harmonic contribution changes. To verify the performance of the propose
method, a logistic regression classifier will analyse the result and give the accuracy and positive rate
percentage of the propose method. The adequacy of the proposed methodology is tested and verified on
distribution system for several rectifier and inverter-based loads.
