Power-distribution-network light-indicator retrieving monitoring method

Abstract

The invention discloses a power-distribution-network light-indicator retrieving monitoring method. The power-distribution-network light-indicator retrieving monitoring method includes the following steps that a power-distribution-network light indicator model is maintained; the information of power-network primary wiring diagrams is maintained; three-layer index directories are built; the three-layer index directories include the plant station, the feeder line and the switching station, and all generated items of the three-layer index directories are linked to the corresponding primary wiring diagrams; a power-distribution-network light-indicator signal processing program is built and used for processing light-indicator signals; light indicators are dynamically queried, and according to the hierarchical relationship of the three-layer index directories, the plant station, the feeder line, the switching station and the light indicators are sequentially queried, all the light indicators of the switching station are finally displayed, and the light indicators of the same device are arranged together. According to the integrated three-layer directories, the power-distribution-network primary wiring diagrams, the power-distribution-network model and the power-distribution-network light-indicator signals are organically integrated to be in the directory, the seamless connection problem of the power-distribution-network information model is solved, the problem that retrieving of light-indicator signals is difficult is effectively solved, and the daily workloads of operation persons and maintenance persons are reduced.

Description

technical field [0001] The invention relates to a method for retrieving and monitoring an optical plate of a distribution network, belonging to the technical field of distribution automation systems. Background technique [0002] Distribution network is an important infrastructure for urbanization. With the acceleration of urbanization, the development of modern distribution network has ushered in a critical period where opportunities and challenges coexist. At the same time, under the encouragement of the national energy saving and emission reduction policy, the future distribution network will not only have a large amount of information, but also have a complex structure. Distribution network technology has a greater impact. [0003] In traditional substations, optical plates are an important means for operators to monitor the operation status of equipment in the station and protection actions. Optical nameplates are mainly triggered by hardware contacts such as on-site ...
