Abstract

The invention relates to a topology search method based on distribution looped network automatic mapping. The method includes: judging whether a search device is a outgoing breaker or a distribution switch; if the search device is the outgoing breaker, searching power supply paths on an island where the outgoing breaker is and power paths of related islands connected to the island; integrating all devices and attribute information structures thereof on the searched power supply paths; if the search device is the distribution switch, judging on and off state of the distribution switch; when the distribution switch is on, searching outgoing breakers on the path of the distribution switch, and searching to integrate related information; when the distribution switch is off, judging whether the distribution switch is a closed-loop switch or not; if so, searching power supply paths at two ends of the closed-loop switch, and searching to integrate related information; if not, searching the current power supply paths, and searching to integrate related information. By the method, automatic mapping model information required by devices is automatically searched by means of topology according to scenes, and good portability is achieved.

Description

technical field [0001] The invention relates to a method for analyzing a power system network and obtaining the topology structure of the network. Background technique [0002] The topology structure is not only the basis of advanced applications such as power flow analysis and state estimation, but also the basis of other application software for power system network analysis. Its task is to calculate the real-time structure of the network through a certain algorithm according to the switching status of the switch in the power network Topology, and then perform more advanced calculations to understand the operating status and safety and stability of the power network, or obtain topology data for use in power system applications. [0003] There are mainly the following types of real-time network topology algorithms: [0004] 1. Depth or breadth search method [0005] Early network topology analysis is to use the stack technology to search. Generally, the topological struc...
