Abstract

The invention discloses a power distribution network power failure simulation analysis method and system based on equipment topology relationship, comprising the following steps: obtaining source point equipment information to be powered off; starting from the source point equipment on the topology network according to the source point equipment information Perform single-source breadth tracking to obtain all power sources supplying power to the source equipment and all encountered distribution transformers; perform multi-source tracking from multiple power sources on the topology network to obtain all encountered live transformers; all live transformers Deleted from multiple distribution transformers, the rest is a dead distribution transformer. The present invention can significantly improve the comprehensiveness and accuracy of the determination of the power outage range.

Description

Technical field [0001] The present invention relates to the technical field of power systems, and more particularly to a power-off and power-off simulation analysis method and system based on a device topological relationship. Background technique [0002] At present, the power system technology has generally established a distribution network equipment database. The identification number of the distribution network device, the device type and other geographic information, the geographic location, direction, and other geographic information, the geographic position, direction, direction, etc. Topological information such as relationship, switch status. The power outage range can be determined by reading the data in the database when determining the power distribution range of the power outage. Using the distribution network equipment database development distribution network management system, the spatial information and attribute data of the grid device can be displayed on the v...
