This paper made some researches of modeling on the systems of the large-scale photovoltaic(PV) power station, and established the PV model, the rectifier and inverter circuits and so on. Using MATLAB and PSASP, simulation and analysis of grid-connected characteristics about the large-scale PV power station in weak grid systems were carried out, focusing on the transient stability in the fault condition of the line-side and the power quality. These two simulation results had good consistency, which demonstrated the accuracy of the large-scale PV power station model in this paper and the analysis of its grid-connected characteristics. The conclusion of this paper will provide some theoretical basis of improving the stability of grid-connected and reducing the harmonic current in weak grid systems, and will also provide some theoretical basis and the guide of grid-connected for the new energy strategy of our country in the future.
