Method and system for diagnosing network frame load problems of power distribution network

The invention discloses a power distribution network frame load problem diagnosis method and system, and relates to the field of power distribution network safety. According to the power distribution network frame load problem diagnosis method and system, a centralized monitoring platform is established, so that centralized supervision on the whole power distribution network in a region is realized from power grid-connected monitoring of a power source, long-distance power transmission monitoring of power to power utilization end monitoring after the power at the tail end enters a power distribution transformer substation; the power transmission process is monitored in all directions, when faults occur, the diagnosis system automatically switches into corresponding node data information, analyzes data, compares the data to obtain the possibility of corresponding load problems, lists possible faults, judges the rationality of the faults at the moment, and determines the power transmission process according to
