英文摘要	A large number of photovoltaic access to the power grid will lead to new characteristics of grid harmonics due to the increase of the scale of converter equipment, and photovoltaic power stations are prone to generate harmonic interaction with the distribution network transmission lines to affect the power quality, so it is of great significance to study the harmonic distribution characteristics and resonance degradation phenomenon of photovoltaic power station. In this paper, the photovoltaic power station model is firstly established to analyze its harmonic output characteristics, and then the photovoltaic power station model is connected to different locations of the IEEE34 node test system to study the impact of different access locations on harmonic distribution. Finally, according to the resonance degradation mechanism of transmission lines, the variation of harmonic amplification coefficient and resonant deterioration degree of transmission lines with different distance and different harmonic frequency are studied. The effectiveness of the model is validated by simulation, and the harmonic distribution law and harmonic interaction factors of photovoltaic power stations are obtained, which provides a theoretical basis for harmonic control of photovoltaic power station. © 2019 IEEE.
