A railway photovoltaic power generation grid-connected station access system comprises a photovoltaic power generation unit, a photovoltaic grid-connected outlet cabinet, a photovoltaic grid-connected access cabinet and a power grid system. The photovoltaic power generation unit is connected into the photovoltaic grid-connected access cabinet through the photovoltaic grid-connected outgoing line cabinet and is connected into a railway 10kw substation and a power grid system through the photovoltaic grid-connected access cabinet, and a fault monitoring and intelligent protection system is connected between the photovoltaic grid-connected outgoing line cabinet and the photovoltaic grid-connected access cabinet. The fault monitoring and intelligent protection system is used for monitoring the output power of the photovoltaic power generation unit and the load power of the railway system, and when the output power of the photovoltaic power generation unit is greater than the load power of the railway system, the residual power of the photovoltaic power generation unit is input to the power grid system for the residual power access. And when the output power of the photovoltaic power generation unit is smaller than the load power of the railway system, the power grid system is controlled to supply power to the railway system, thereby ensuring the power supply reliability of railway facilities.
