Problems solved by technology

The traditional monitoring method is generally based on some important single variables in the distribution network and underground cables to be monitored separately, but there is generally a large correlation between the data reflecting the process characteristics, and the single variable monitoring cannot detect the interaction between multiple va

Abstract

The invention discloses a BIM-model-based distribution network and underground cable fault detection method comprising steps of building an original BIM model, carrying out normal state data modelingand carrying out online data detection. At the step of building an original BIM model, structural characteristics of distribution network and underground cable distribution are obtained comprehensively; at the step of carrying out normal state data modeling, several kinds of variable process data in a normal stable operation state of a distribution network and underground cable are inputted into the BIM model based on a neighborhood preserving embedding algorithm and a statistic amount and a corresponding statistic threshold are calculated; and at the step of carrying out online data detection, process variable data collected in real time during the operation process of the distribution network and underground cable are projected to the model constructed by normal state data modeling, a statistic amount is calculated; and the statistic amount is compared with the statistic threshold calculated by the normal state data modeling to obtain a detection result. Therefore, BIM-model-based multi-variable distribution network and underground cable fault detection is realized; and the operation and maintenance management safety of the distribution network and underground cable is improved.

Description

technical field [0001] The invention belongs to the technical field of power grid distribution network security, and in particular relates to a BIM model-based distribution network and underground cable fault detection method. Background technique [0002] The construction of the distribution network is an important part of the power system. It is the basis for realizing the two-way interaction between the power grid and customers. With the improvement of the national economy and the improvement of people's living standards, the requirements for the stable operation of the distribution network are getting higher and higher. , so the fault warning design of the distribution network is a necessary link in the power grid system. [0003] When the distribution network fails, there will be a large-scale power outage, which will cause large economic losses and negative social impacts on the power grid enterprises and users. How to warn the power grid failure in a safe, efficient a...
