【 摘 要 】

With the development of renawable energy generation systems, it not only relieves energy shortages and environmental pollution problems, but also brings harmonic pollution, which is related with power quality decetion. A modified harmonic and interharmonic analysis method is studied in this paper. By applying window interpolation, signal reconstruction, 5-point modified algorithm, and other signal handling methods, harmonic and inharmonic components are separated exactly, improving harmonic and interharmonic detection accuracy under new energy application, providing accurate signal basis and reference for further harmonic suppression and distribution network reconstruction scheme, and finally improving power quality.
