Power distribution automation distributed differential protection system and method based on 5G edge calculation

The invention discloses a power distribution automation distributed differential protection system and method based on 5G edge computing, and the system comprises a power monitoring module which builds network communication between a distributed power monitoring master station and a distributed power monitoring sub-station and a distributed power monitoring terminal based on the bandwidth greater than or equal to 2Mbit/s; the power grid state monitoring module gives a decision through calculation and analysis based on the obtained power grid network state, and carries out dispatching configuration of the power distribution network; the power grid load processing module is used for eliminating network delay of communication among the load shedding master station, the load shedding substation and the user-side intelligent network load interaction terminal; and the network difference protection module is used for comparing vectors of current values at two ends or multiple ends at the same time through a differen
