Transformer substation monitoring system debugging method based on digital twinning

Abstract

The invention relates to a transformer substation monitoring system debugging method based on digital twinning, and the method employs a transformer substation monitoring system which comprises a station control layer, a spacing layer and a process layer. Comprising the following steps: S1, collecting configuration data of a running transformer substation; S2, realizing offline configuration and debugging work of an online system; S3, restoring and backing up the transformer substation on site; and S4, displaying static information and dynamic real-time running information of the transformer substation. The system has the advantages that the debugging interval of the transformer substation can be operated and visualized through the 3D holographic image information display system, a three-dimensional live-action model can be formed, after the digital twinning monitoring background is subjected to debugging change, the digital twinning monitoring background can automatically correspond to the change of the three-dimensional model, and the debugging efficiency of the transformer substation is improved. Defects such as abnormal configuration of a field operation transformer substation database can be synchronously judged through the digital twinborn monitoring background, the number of times of field repeated defect processing by maintainers in the past is reduced, and more than 30% of human resources can be saved.

Description

technical field [0001] The invention relates to a debugging method for a substation monitoring system based on a digital twin. Background technique [0002] With the rapid development of my country's social economy, the scale of power grids has been continuously expanded, and the scale of substation construction has continued to increase. As a result, the amount of infrastructure work required to debug the monitoring system of substation maintenance plants has become increasingly heavy. The traditional on-site monitoring system based on human resources investment The commissioning mode has greatly restricted the improvement of the overall secondary professional safety, quality and efficiency of substation maintenance. For example, in the traditional mode, the 220kV substation has a new 220kV line interval.

[0002] With the rapid development of my country's social economy, the scale of power grids continues to expand, and the scale of substation construction continues to increase. As a result, the amount of infrastructure work for the commissioning of substation maintenance plant monitoring systems is becoming increasingly heavy. Traditional on-site monitoring systems that rely mainly on human resources The commissioning mode has greatly restricted the improvement of the secondary professional safety, quality and benefit of the substation overhaul. For example, in the traditional mode, a new 220kV line interval is installed in the 220kV substation. Before the equipment installation is completed, the automatic commissioning personnel need to Enter the substation site nearly a week in advance to carry out preparatory work such as network construction and system configuration, but often during the preparatory work, the equipment installation of the infrastructure unit does not yet have the actual debugging conditions, and the automated commissioning personnel fall into "running broken legs", "sitting The embarrassing situation of "watching", which led to the innocent consumption of human resources, and the carrying capacity of the team was also affected to a certain extent
