Shanghai has successfully developed intelligent inspection technology for distribution stations based on the Internet of Things

In recent years, with the rapid development of Shanghai, the electricity load has been rising, the number of distribution stations has also been increasing, and the workload of distribution station inspection is large
.
To this end, Shanghai Nan Power Supply Company has developed an intelligent inspection technology for distribution stations based on the Internet of Things, which realizes the mode of inspection and distribution without entering the station, and can complete the entire inspection, recording and other work
that originally took at least 35 minutes in less than 5 minutes.

On February 18, next to a 10-kilovolt distribution station on Puxiu Road in Shanghai's Minhang District, Luo Lei, an operation and maintenance worker of Shanghai Nan Power Supply Company, was in a yellow electric inspection vehicle, staring at the monitoring data full of screens in the interactive interface and reporting
to the background monitoring personnel.
Wei Jinping, head of the distribution operation and maintenance team of Shinan Power Supply Company, said that the traditional inspection process is inspected by professional distribution operation and maintenance personnel, which has many inspection items, takes a long time, and has to re-enter the data into the system after recording, and the steps are complicated
.
Now as long as you operate simply on the screen outside the station, close to the place where the wireless signal is transmitted, you can see various indicators, which is convenient for operation and maintenance personnel to understand the situation
in the station more intuitively.

It is reported that behind the seemingly simple operation is a set of flexible intelligent mobile power quality monitoring platform based on Industry 4.
0 characteristics, and integrates a variety of advanced technologies
such as the Internet of Things and visible light Li-Fi communication.
In the distribution station, various signals are collected by sensors and transmitted to the data storage center
in the main control room through visible light communication Li-Fi technology.
After data processing, it is transmitted from the distribution station terminal to the mobile inspection vehicle through dual-band wireless communication technology, and displayed to the distribution operation and maintenance personnel through a friendly human-computer interaction interface, and then the mobile operator's 3G/4G network is used to send the data to the background communication port through the public network APN isolation technology, so as to realize the intelligent operation and maintenance of the distribution station
.

According to reports, the intelligent inspection technology can not only be used for the inspection of 10 kV distribution station, but also has broad promotion and application prospects
in higher voltage level substations with perfect communication transmission hardware conditions in the station.
For example, in the substations of 500 kV and above that have realized intelligent robot patrol in Shanghai, the intelligent robot can send more detailed equipment operation and maintenance data directly to the background data monitoring platform through its own communication equipment, which greatly reduces the labor cost of equipment operation and maintenance patrol and effectively improves the data accuracy
