Method for polling versions and faults of power distribution equipment, power distribution terminal and power distribution master station

The invention relates to the technical field of power systems, and discloses a method for polling versions and faults of power distribution equipment, a power distribution terminal and a power distribution master station. The power distribution master station sends the polling instruction regularly, the power distribution terminal obtains the ICD configuration file of each power distribution device in the area to which the power distribution terminal belongs according to the polling instruction, the actual data of the power distribution device and the corresponding ICD configuration file are mapped, and the obtained model mapping file is distributed to the power distribution master station. The method comprises the following steps: performing instantiation model construction on power distribution equipment by a power distribution master station, determining whether a version needs to be updated according to a comparison result of software version information of an instantiation model and latest version inform
