This paper is focusing on the problem that the access point of PV power station is very close to electric railway traction station, according to the harmonic frequency and amplitude characteristics of the two themselves, the harmonic transmission characteristics of AC transmission line are considered, and the harmonics of the public grid between the two are analyzed according to the principle of the interaction between multiple harmonic sources in GB. Finally, a power grid simulation model with photovoltaic power station and electric iron equivalent model is built on the PSCAD/EMTDC simulation platform, and the harmonic interaction between the electric railway and the photovoltaic power station is analyzed, and the effectiveness of the method is validated.
