Labeling method and device for multi-source measurement in power distribution network wide-area measurement control system

Abstract

The invention relates to a labeling method and device for multi-source measurement in a power distribution network wide-area measurement control system, and the method comprises the steps: obtaining ameasurement primitive group according to multi-source measurement information; weighting the occlusion areas of other non-measurement primitives on the single line diagram by using the measurement primitive group, and determining a labeling position according to the obtained weighted value; marking a measurement primitive group in the single line diagram according to the marking position, whereinthe multi-source measurement information is data of a plurality of data sources for the same measurement target. According to the embodiment of the invention, the method achieves the automatic marking of multi-source measurement, can avoid the shielding of important primitives, guarantees the tidy arrangement of effective data sources, improves the tidy and beautiful degree of a single line diagram, and guarantees the information comprehensiveness. And meanwhile, the repeated workload is small, the manual maintenance workload is effectively reduced, and the labeling efficiency is improved, sothat the related information of the power equipment can be more accurately and comprehensively acquired in real time through the single line diagram.

Description

technical field [0001] The present disclosure relates to the field of electric power technology, and in particular to a method and device for marking multi-source measurements in a distribution network wide-area measurement control system. Background technique [0002] The single-line diagram of the Distribution network-Wide Area Measurement System (D-WAMS) describes the topological connection relationship of power equipment. In the case of incomplete measurement and labeling in the single-line diagram, it needs to be supplemented Operation; in related technologies, manual marking is used to complete measurement markings, which requires a large amount of repetitive work, and it is difficult to ensure orderly arrangement; or the measurement markings are completed through program marking, which easily blocks other graphics elements; thus, the one-line diagram cannot be used Accurate, real-time and comprehensive acquisition of relevant information of power equipment.
