Fault accurate identification method based on real-time intra-station graph mapping

Abstract

The invention discloses a fault accurate identification method based on real-time intra-station graph mapping. A fault vector analysis and fault diagnosis platform based on a primary topological graph scalable vector graph and a universal information model is built; fault equipment substations needing fusing are determined for a search route through a fault amount flow direction, and a macrozone information fusion platform is formed; information fusion is carried out based on the macrozone information fusion platform, and an information closed loop and an oscillograph are fused into a vector analysis graph to carry out accident property analysis and assistant decision making; in the process of accident property analysis and assistant decision making, fault information is collected and fused in an expanded macrozone, and the fault property of a fault element is judged. On a fault scene, intra-station equipment serves as the background, the flowing direction of fault current serves as an analysis interface of a display mode, judgment of the fault element can be achieved rapidly, and the fault judgment on a multi-element connection device with a converge function is especially visual and effective.

Description

technical field [0001] The invention relates to the field of accurate fault identification, in particular to an accurate fault identification method based on real-time intra-station map mapping. Background technique [0002] As the scale of the power grid continues to expand and the connection between the power grid continues to strengthen, the probability of power grid failures and partial failures leading to expanded coverage continues to increase. In order to achieve rapid identification and accurate positioning of faults, the coverage of the fault recorder networking system continues to increase. When the power grid fails, the relevant fault recording information can be uploaded to the dispatch center in time, but the fault data at each interval cannot be displayed uniformly and intuitively on the station map, and it is difficult for the dispatcher to accurately identify and monitor the fault by calculating the fault current vector sum of the relevant area at the time of ...
