Abstract

The invention discloses a position identification method of a distributed topological structure, an intelligent terminal and a storage medium, which are applied to a cable type power distribution network, and the method comprises the steps: in a monitoring period, enabling a first intelligent terminal to sample a body switch state, a bus voltage and a branch current, and calculating a sampling result of a local side; according to the sampling result of the side, performing first pre-judgment on the on-off condition of a connection channel between the ring network point monitored by the first intelligent terminal and the ring network point monitored by the second intelligent terminal to obtain a first pre-judgment result; performing secondary judgment on the first pre-judgment result according to a first rule to obtain a judgment result of the on-off state of the channel; according to the judgment result, obtaining the topological relation of the feeder line where the first intelligent terminal is located in the current operation mode and the upstream and downstream relation of the first intelligent terminal in the power supply channel. According to the invention, each intelligent terminal can realize online topology change identification according to own state measurement and information interaction between the intelligent terminal and the adjacent intelligent terminal.

Description

technical field [0001] The application relates to the technical field of the medium-voltage distribution network, and in particular to a location identification method of a distributed topology structure, an intelligent terminal and a storage medium. Background technique [0002] With the development of distributed power generation, the power flow distribution of active distribution network is becoming more and more complex and changeable, and the number of objects that need to be monitored is increasing. In the future, medium voltage distribution network will develop in the direction of distributed collaborative control. That is, distribution terminals with considerable intelligent decision-making capabilities are deployed at key distribution ring network points. Through the interactive communication between adjacent intelligent terminals to exchange monitoring and judgment information, various control, protection and regulation functions of the distribution network are rea...
