Risk Assessment of Ferromagnetic Resonance in Series Compensation Lines with New Energy Access

In view of the multiple power quality problems caused by photovoltaic and wind power access,aseries compensation intergrated energy effciency optimization model for distribution lines with new energy sources is established.The optimal compensation capacity and compensation location are obtained by calculation.In order to avoid series compensation induced ferromagnetic resonance in distribution network, the mechanism and suppression measures of intensified ferromagnetic resonance in new energy access distribution network are studied, and the risk assessment model of ferromagnetic resonance in series compensation line with new energy access is established.The ferromagnetic resonance risk assessment is carried out to ensure the safe and stable operation of series compensation line.
