A novel software for harmonic analysis and harmonic source location

Abstract

To better identify harmonic pollution source, a software for harmonic analysis and harmonic source location is introduced in this paper. Firstly, the function framework of the software is established and the technical route of the software is designed. Besides, harmonic analysis is conducted by interpolation FFT algorithm with Hamming windowing. Location of harmonic source is determined by sparse reconstruction algorithm in allusion to undetermined harmonic measurement equation set. Furthermore, to ensure the observability of power network, the configuration algorithm of harmonic measurement nodes is given. The software has a good practicability, strong data processing ability, easy system maintenance, good application extension function and promotional value.
