摘要：When the Distribution network is disturbed, the Potential transformer(PT) saturates. It can cause distortion of voltage and current waves to generate harmonics, which further causes ferromagnetic resonance in the Distribution network. This article aims to analyze the effect of high-frequency and wide-frequency harmonics caused by photo-voltaic on the ferromagnetic resonance of the Distribution network. Firstly, the resonant circuit and resonance conditions of the underground neutral Distribution network are described. Secondly, based on resonant circuit, relationship between the PT flux linkage and harmonic voltage is established. The relationship between harmonics caused by photo-voltaic power generation and the influence of the harmonics on the ferromagnetic resonance of the Distribution network is analyzed. The conclusion is that this harmonic has an effect on the ferromagnetic resonance of the Distribution network. The effect of low-order harmonics is more obvious than that of higher harmonics. Finally, MATLAB/Simulink is used to verify the correctness of the theoretical results obtained.
