Intelligent transformation plan for substations. 1 article to help you make it clear!

Substations

Substations are geographically dispersed and widespread. The manual regular inspection of smart substations has a huge workload of operation and maintenance, low operation and maintenance efficiency, and high manual operation and maintenance costs.

The pseudo-intelligent mode of “monitoring machines and people monitoring” urgently needs an intelligent mode to liberate people from repetitive and simple work.

The inspection method of traditional handheld thermometers cannot supervise the inspection quality and is difficult to supervise. Due to untimely inspections, the equipment is running with problems, which eventually causes the production operation to stop.

Overview of the plan

This plan realizes the intelligent transformation of traditional substations by adding intelligent devices and various IoT smart sensors to the substation room.

By deploying intelligent fusion terminal devices with edge computing functions, intelligent perception and identification of substation grid operating conditions, equipment status, environmental conditions and other auxiliary information. And upload necessary data to the flat layer according to production and management needs.

With the help of existing power Internet of Things related technologies and various sensors, it has intelligent functions such as abnormal operation alarm and potential fault analysis of substations, improves the inspection efficiency of substations, and promotes the reliability of distribution network power supply.

Through the platform layer and edge nodes to coordinate data processing, combined with big data, artificial intelligence and other technologies to achieve accurate monitoring of the distribution network operation status, and conduct online analysis and deep mining of data, to achieve comprehensive, full-scenario panoramic perception of substation operation status.

Overall architecture

Cloud: Receive data and issue instructions; real-time display of monitoring data, historical data statistics, analysis, trends and other chart information.

Edge: Deploy edge computing devices and AI cameras, empower the cameras in the station, and create an intelligent analysis front end; deploy DTU, link with the sensors in the station to realize intelligent inspection of the substation;

Station: Add intelligent terminals and configure patrol points

Construction content

Deploy 2 million pan-tilt zoom gun cameras, connect to AIBOX to determine the operating status of the equipment.

Deploy 2 million pan-tilt zoom gun cameras, connect to AIBOX to determine the operating status of the main transformer and the early warning of dangerous events in the station.

Deploy passive wireless temperature measurement devices to realize the alarm of abnormal heating of the main transformer.

Deploy AIBox to empower the main control and 6KV high-voltage room cameras to determine the operating status of the equipment.

Deploy 2 million pan-tilt zoom ball cameras to monitor the main control room, and connect to AIBOX to perform intelligent analysis of the equipment status and alarm abnormal status.

Application value

Actively monitor substations to improve management efficiency

The three principles of online people, online objects, and online management allow managers to achieve unmanned operation and supervision of the entire substation without leaving their homes, changing the user’s maintenance mode from “passive repair mode” to “active prevention mode”

Realize “unmanned operation” of substations

The power information, environmental information, video monitoring information and other data of the substation are transmitted to the central monitoring room through the communication management machine, and the central monitoring room implements remote, centralized monitoring and linkage control of the substations in the system, realizing the true sense of “unmanned operation” of substations.

Reduce operating costs

Realize intelligent monitoring of station houses, improve management efficiency, realize 7*24 unmanned monitoring and real-time abnormal alarm, save 70% of labor costs, and save 50% of management costs. In addition, potential risks can be predicted in advance, intervene in advance, and reduce the cost of accident handling.

Avoid duplicate investment

The system has the characteristics of openness, scalability, compatibility and flexibility, which can adapt to product upgrades and avoid duplicate investment.
