SUMMARYThis paper presents a systematic technique to solve for the harmonic and interharmonic interaction between a power system and several harmonic sources. The technique can potentially analyze any power electronic source that can be modeled as a piece-wise linear circuit. Harmonic source data is input to the procedure using a standard lumped parameter description. Two test cases are presented. The first test case shows the interaction between a static var compensator (SVC) and an HVDC in unbalanced operating conditions. The second test case analyzes a complete current source variable speed drive connected to a distribution network. Both test cases include power constraints.

“…If 100 or more of the 200 3 second values are either 'nonconforming' or unavailable due to lack of measurement data, then the 10 min value(s) shall be marked as 'nonconforming'. 4 The 2 h rms harmonic value will be obtained by taking the rms of the 10 min rms values during each 10 min interval. Each 2 h interval shall be contiguous and nonoverlapping.…”

“…To extract harmonics accurately it is important to find the fundamental frequency of the data to be analyzed. In previous papers [2]- [4] the authors have shown the difficulty of extracting a synchronized sampling frequency from the analyzed signal and discussed the effect of the deviation of the fundamental in the presence of the interharmonics. This thesis suggests a novel 3 approach to overcome the difficulties even if the interharmonics are present in a frequency spectrum near the fundamental.…”

This thesis describes a novel approach that utilizes a special property of the Hanning window to accurately detect the fundamental frequency of the data signal in the presence of harmonic and interharmonic interference. After obtaining the fundamental frequency, the same procedure is applied to all possible harmonics to be filtered for further analysis of the interharmonics. The proposed approach is validated using numerical tests. In the literature, different authors have shown the difficulty of extracting a synchronized sampling frequency from the analyzed signal and discussed the effect of deviation of the fundamental in the presence of harmonics. This thesis suggests a new approach to overcome the difficulties, even if the interharmonics present are in frequency bins near the fundamental.In order to perform the interharmonic analysis, the author followed the IEC standard draft signal processing recommendations, with the exception of using a
