Abstract

The issue of harmonic pollution in the power grid has received widespread attention. The harm of harmonics includes causing equipment overheating, shortening equipment life, increasing additional line losses, and reducing operational efficiency. Accurately calculating harmonic impedance is one of the keys to studying harmonic problems. Based on harmonic measurement data at common connection points, existing scholars have proposed several non-invasive harmonic impedance estimation methods. After calculating the harmonic impedance, it is necessary to verify the correctness of the calculation results. Accurately solving the harmonic impedance of the system and user sides is of great significance for accurately quantifying harmonic responsibility, guiding the development of filter design related work, guiding harmonic suppression and resonance mitigation, and other aspects.However, there is currently no unified method to verify the correctness of obtaining harmonic impedance. Therefore, this article proposes a method for determining the accuracy of harmonic impedance calculation results.
