Disturbed topological structure identification method at the end of power grid in station area based on centralized dispatching

Abstract

The invention discloses a method for identifying a disturbance topological structure at the end of a power grid in a station area based on centralized scheduling, relates to the technology of power system information processing and automatic identification, and belongs to the technical field of power generation, power transformation or power distribution. By constructing the network routing topology of the low-voltage distribution network intelligent perception system, the method identifies the type of acquisition equipment in the constructed network routing topology, and constructs the physical topology of the meter box monitoring unit from bottom to top by traversing the query. The physical topology of the branch box monitoring unit removes the branch box monitoring unit and the meter box monitoring unit without parent nodes, and integrates the physical topology of the meter box monitoring unit and the branch box monitoring unit according to the relationship between the parent node and the child node. The physical topology structure obtains the terminal disturbance topology of the power grid in the station area, which is conducive to the refinement of management and the practical application of the project, and can provide accurate basic files of the substation-line-household relationship in the station area for the analysis of segmental line loss and station area line loss.

Description

technical field [0001] The invention discloses a method for identifying a disturbance topological structure at the end of a power grid in a station area based on centralized scheduling, relates to power system information processing and automatic identification technology, and belongs to the technical field of power generation, power transformation or power distribution. Background technique [0002] As the construction of the State Grid Corporation's electricity consumption information collection system enters the stage of deepening application, the requirements for benchmarking assessments in the same industry are increasing day by day. Due to management reasons or the division of the station area, the relationship between households in the station area is inaccurate and the line loss in the station area is abnormal. The phenomenon is relatively common, and it is difficult to meet the needs of lean management. [0003] Aiming at the problem of inaccurate basic archives of ...
