The invention provides a fault positioning method and device for an integrated energy power distribution network, and the method comprises the steps: building a wireless sensor network based on the power distribution network, and selecting a plurality of wireless sensors in the wireless sensor network as anchor nodes; when a wireless sensor with abnormal information appears in the wireless sensor network, taking the wireless sensor with the abnormal information as a target node; obtaining the weight Wi of the corresponding anchor node according to the RSSI value of the anchor node corresponding to the target node; and obtaining the position of the target node according to the weight Wi and the position of the anchor node. According to the method, the weight of the anchor node is determined through the RSSI value of the anchor node, and the position of the target node is further determined according to the weight and the position of the anchor node, so that the positioning efficiency and accuracy of the fault point of the power distribution network are effectively improved.
Description
technical field [0001] The invention relates to the field of electric power technology, in particular to a fault location method and device for an integrated energy distribution network. Background technique [0002] With the development of new energy sources, electric energy has gradually become the main form of energy utilization for people. As a power system that directly provides electric energy to users, the distribution network has the closest relationship with users, and its impact on users is also the most direct. The distribution network is located at the end of the power system and is directly connected to the users. The power supply of the entire power system to the users is ultimately realized and guaranteed through it. It is important to detect the distribution network, grasp its operation and locate the fault point of the distribution network. very necessary. At the same time, with the continuous development of sensor technology and wireless communication tec...
