Method for simplifying topology of high-voltage distribution network

The invention discloses a method for simplifying the topology of a high-voltage distribution network. The method includes the following steps: reading a CIM/XML file, where names of all power-network devices and association tables of all the power-network devices in the high-voltage distribution network of a set area are recorded, in an SCADA database; leading a device list of the to-be-read power-network devices in the CIM/XML file; according to the device list, reading the power-network devices, matched with the device list, in the CIM/XML file and the device states corresponding to the power-network devices; judging the voltage grades of the read power-network devices, and classifying the power-network devices into the high-voltage-side power-network devices and the low-voltage-side power-network devices; according to the running conditions of the high-voltage-side power-network devices and the wiring direction of the high-voltage distribution network, connecting the high-voltage-side power-network devices with the low-voltage-side power-network devices to form a simplified topological graph.
