Distributed photovoltaic grid-connected monitoring system

The invention relates to the technical field of photovoltaic modules, in particular to a distributed photovoltaic grid-connected monitoring system, which comprises an intelligent electric energy meter; a data receiving module; a data acquisition module; a computer center; an RS485 communication module; a grid connection point interaction data storage module; an electric quantity management module; an electric quantity statistics module; an electric quantity excess prompting module; and a protection tripping module. According to the invention, additional wiring adjustment is not needed, anti-islanding protection can be realized after the photovoltaic switch provided with the distributed photovoltaic grid-connected intelligent monitoring system is connected, when line faults such as voltage loss, undervoltage, overvoltage, overload, short circuit and the like occur in a line, the function of protecting the line is realized, and when the line voltage recovers to a normal value range, the photovoltaic switch can
