A sensing installation method and system for a gas-insulated substation

Abstract

The present invention provides a sensing installation method and system for a gas-insulated substation. The method comprises sensing environmental information and panoramic video information within a dustproof shed at the installation site; uploading the environmental information and panoramic video information to a cloud platform; and processing the uploaded data on the cloud platform, comparing and verifying the data with a preset threshold or template. If the data fails the verification, an abnormality message is sent to a terminal device. The present invention sets up sensing equipment at the GIS installation site to obtain real-time environmental information and panoramic video information, compares them with pre-stored standard values, quickly identifies abnormal information, and sends it to the terminal device. This improves the monitoring efficiency of the installation process and enables timely reporting of abnormal installation information when it occurs, avoiding more serious consequences.

Description

Technical Field

[0001] The present invention relates to the technical field of substation installation management, and in particular to a sensing installation method and system for a gas-insulated substation. Background Art

[0002] A GIS (Gas Insulated Substation) is a metal-enclosed switchgear that uses gas, in whole or in part, as the insulating medium instead of air at atmospheric pressure. It is a high-voltage power distribution device consisting of a circuit breaker, busbars, disconnectors, voltage transformers, current transformers, lightning rods, and bushings.

[0003] The installation of a gas-insulated substation involves numerous steps and extremely high requirements. Currently, this process requires repeated on-site inspections and testing, which consumes significant manpower and reduces installation efficiency. Summary of the Invention

[0004] The present invention provides a sensing installation method and system for a gas-insulated substation, which are used to solve the problem of low installation efficiency of existing GIS.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A first aspect of the present invention provides a sensing installation method for a gas-insulated substation, the method comprising:

[0007] Perceive environmental information and panoramic video information in the dustproof booth at the installation site;

[0008] Uploading the environmental information and panoramic video information to the cloud platform;

[0009] The cloud platform processes the uploaded data, compares and verifies the data with preset thresholds or templates, and sends abnormal information to the terminal device if the data fails the verification.

[0010] Furthermore, when the verification fails, the method further includes:

[0011] Obtain historical data of the current verification item, perform statistical analysis, and send the analysis results to the terminal device.

[0012] Furthermore, the statistical analysis process is specifically as follows:

[0013] Preprocess the historical data, remove abnormal data through cluster analysis, and form a historical data set;

[0014] Sorting the elements in the historical data set according to different rules to form multiple sub-data sets;

[0015] Match the corresponding comparison strategy to each sub-dataset to obtain the cause of the abnormal information and the alarm level.

[0016] Furthermore, the rules include sorting by time and sorting by data size.

[0017] Furthermore, if the rule is sorted by time, then the corresponding comparison strategy is matched, and the specific process of obtaining the cause of the abnormal information is as follows:

[0018] Check whether the values ​​of the elements before the abnormal element are close to the current abnormal element in sequence;

[0019] If so, the current abnormal information is a historical accumulated fault; if not, the current abnormal information is a sudden fault.

[0020] Furthermore, the rule is to sort the data in order of size, then the corresponding comparison strategy is matched, and the specific process of obtaining the cause of the abnormal information is as follows:

[0021] Check the difference between the value of the element in the array and the preset threshold value, and determine the number of the differences within the preset range. If the number exceeds the preset number, the current abnormal information is a serious fault, otherwise it is a normal fault.

[0022] An embodiment of the present invention further provides a sensing installation system for a gas-insulated substation, the system comprising:

[0023] The environmental monitoring unit is installed in the dustproof booth to sense the environmental information of the installation site;

[0024] The video monitoring unit is installed in the dustproof booth to obtain panoramic video information of the installation site;

[0025] An edge agent, configured to upload the environmental information and panoramic video information to a cloud platform;

[0026] The cloud platform is used to process the data uploaded by the edge agent, compare and verify the data with the preset threshold or template, and send abnormal information to the terminal device if the data fails the verification.

[0027] Furthermore, the environmental monitoring unit includes a temperature and humidity sensor, a dust concentration sensor, and a gas concentration sensor.

[0028] Furthermore, the video monitoring unit includes a 360° panoramic camera.

[0029] Furthermore, the system also includes a remote communication unit, through which video and voice intercom is performed between the terminal device and the installation site.

[0030] The perception installation system of the second aspect of the present invention can implement the method in the first aspect and the various implementation methods of the first aspect, and achieve the same effect.

[0031] The effects provided in the summary of the invention are only the effects of the embodiments, not all the effects of the invention. One of the above technical solutions has the following advantages or beneficial effects:

[0032] 1. The present invention sets up sensing equipment at the GIS installation site to obtain real-time environmental information and panoramic video information, compares it with pre-stored standard values, quickly identifies abnormal information and sends it to the terminal device, thereby improving the monitoring efficiency of the installation process.

[0033] 2.
