Shenzhen Power Supply Bureau will join hands with Huawei to build core competitiveness of smart grid operation

Shenzhen Power Supply Bureau has installed nearly 2000 video on-line monitoring cameras integrated with Huawei AI chip on the transmission site, and developed UAVs equipped with AI chip. The inspection dream of traditional power transmission personnel “sitting in the morning and asking questions, hanging arch and flat chapter” is becoming a reality.

The intelligent inspection system collects a number of cutting-edge technologies and improves the efficiency of transmission line inspection by 80 times

Power grid business digitization is the focus of laboratory. According to the traditional inspection method of transmission line, inspectors have to wade through mountains and rivers to identify line defects by naked eyes, which not only costs a lot of manpower and material resources, but also faces personal safety risks.

“Construction under the line, or kite blowing on the line, may affect the stable operation of the transmission line, but the inspectors can not be on site 24 hours a day.” Wei Qianhu, deputy director of power transmission management office of Shenzhen Power Supply Bureau, said frankly. In recent years, although the Bureau has tried the traditional video online monitoring system, the identification of hidden dangers such as foreign body invasion and construction damage has to be manually analyzed one by one by line patrol personnel or UAV after shooting on the scene.

How to take advantage of digitalization to make line inspection faster and safer? Shenzhen Power Supply Bureau and Huawei will focus on the latest Internet of things and artificial intelligence technology to build a new generation of transmission intelligent inspection system.

The monitoring device equipped with this system has fully covered the Shenzhen transmission line, which can analyze the line defects and abnormalities in real time, feed back and alarm to the background transmission personnel in time. The transmission personnel no longer need to go to the scene to check and take photos, and screen one by one in a large number of original pictures or videos. In the past, it took only 2 hours to complete the manual line inspection in 20 days, and the inspection efficiency increased 80 times. At the same time, the system can timely find the hidden danger points that are not easy to find in the traditional manual ground inspection, and the data collection volume of Shenzhen Power Supply Bureau has increased by 30 times compared with the past.

“One afternoon in April this year, an important transmission line in Shenzhen tripped and went out of power. The atlas core module developed by Huawei Company is equipped with the intelligent recognition algorithm developed by us. It gives an alarm at the first time, and the crane construction suddenly appears under the 62 tower of the line. ” Wei Qianhu said, “after the background video confirmation and technical analysis, the cause of the fault was quickly found. It took less than 50 minutes to remove the fault and restore the power transmission. In the same case, if it happened before, it would take at least one day to find the fault and restore the power transmission.”

Behind the intelligent upgrade of inspection system is the application of many cutting-edge technologies. The system uses the atlas 200ai acceleration module to implement Huawei shengteng AI processor for the first time in the global power industry, and realizes the intelligent identification of the front end of the transmission line by carrying the self-developed algorithm of Shenzhen Power Supply Bureau“ With a large number of historical equipment data and rich practical experience, Shenzhen Power Supply Bureau has developed 51 power algorithms, with an accuracy rate of 90% ” LV Zhining, director of information center of Shenzhen Power Supply Bureau, said.

Combined with Huawei Internet of things end side technology, the system also has the first artificial intelligence internet of things architecture in the power industry. It is reported that this is the first application of HUAWEI’s Internet of things end to side technology in the power industry. It achieves the simultaneous interpreting of different sensors and data such as transmission and transformation of audio and video, images, temperature and humidity and windage, and improves the efficiency of data acquisition.

Shenzhen Power Supply Bureau has also designed a new architecture with AI algorithm component and Internet of things technology as the core, deeply integrating Internet of things and artificial intelligence technology with power business scenarios, realizing new working modes such as smart inspection, smart customer service, smart safety supervision and smart office, and gradually deploying and applying them in power transmission, transformation, marketing and comprehensive fields of Shenzhen Power Supply Bureau.

Huawei Kunpeng processor ecosystem is applied for the first time to promote independent and controllable core equipment

“The key core technology is an important part of the country.” Electric power is related to the national economy and people’s livelihood, is the lifeblood of national economic development. The core equipment can be controlled independently, which is of great significance to ensure the safety of power supply.

“The processor is the” heart “of the computer. Before, the processors used in our information and data center were all foreign brands, and their intellectual property rights and production were not in China. We have been thinking that one day these core equipment can use domestic technology to realize independent control.” Lu Zhining said. In order to break this situation, the Bureau applied Huawei Kunpeng processor ecosystem in the power industry for the first time, and successfully piloted the localization of core software and hardware in the information data center.

“We study Huawei’s Kunpeng architecture to see if we can run our core system. Huawei also provides comprehensive technical support.” LV Zhining said that in order to ensure the implementation of the localization scheme, Shenzhen Power Supply Bureau formulated the test scheme and evaluation model in detail, carried out a large number of reliability tests in combination with the cloud, big data and Internet of things scenarios of southern power grid, and worked with Huawei R & D personnel to overcome the compatibility problem.

“The Kunpeng processor independently developed by Huawei runs very stably, and its technology and performance have basically met our requirements, providing confidence for the localization of our core software and hardware.” LV Zhining said that after the success of the pilot, it is very important to ensure the stable operation of the core business system of Shenzhen Power Supply Bureau on the platform. Therefore, the Bureau has proposed the first business migration verification platform in the power industry. At present, the research and verification work is carried out in an orderly manner, which will strongly promote the formal implementation of localization.

The press conference also introduced the pilot situation of 5g in power business. It is understood that 5g technology has the characteristics of high speed, large bandwidth, low delay, etc., which can be applied to video inspection and monitoring business to realize the return of ultra high definition video and real-time video inspection on the job site. For the first time, Shenzhen Power Supply Bureau and Huawei have implemented the world’s first 5g pilot in the field of power grid real-time control and acquisition based on the national 5g architecture. After promotion, the recovery time of distribution network failure can be greatly reduced, and outdoor high-definition video inspection can be realized.

Joint efforts to create core competitiveness of smart grid operation

In recent years, the 19th National Congress of the Communist Party of China proposed to build a network power, a digital China and a smart society. The outline of the development plan of Guangdong, Hong Kong and Macao Bay area proposed to “take the digital revolution to become a world-class Bay Area”. Recently, the central government issued policies to support Shenzhen to build a socialist first demonstration area and build a core innovation engine of Guangdong, Hong Kong and Macao Bay area. According to the central “digital industrialization, industry digitization” decision-making deployment, China Southern Power Grid Corporation launched an important strategic measure of digital transformation.

Under the wave of digital transformation, Shenzhen power supply bureau is facing new opportunities and challenges, especially how to implement advanced technologies such as “cloud computing, big data, Internet of things, mobile Internet, smart city” and 5g in the power industry through independent innovation.

In order to pool scientific research strength, enhance innovation value and create scientific research industry ecology, Shenzhen Power Supply Bureau has built the innovation and entrepreneurship base in 2018, and established a number of scientific research platforms covering the core technology of power industry chain. ICT laboratory is the first joint innovation laboratory established by Huawei and power enterprises, and it is also one of the most important platforms of the innovation and entrepreneurship base.

At present, Shenzhen Power Supply Bureau and Huawei are actively promoting the further application of artificial intelligence internet of things architecture. Through this architecture, we can identify the safety helmet, clothing, live area crossing and substation UAV intrusion, and solve the pain points of on-site safety supervision. Especially when the operators mistakenly enter the live working area, the real-time alarm will be issued, which greatly reduces the probability of accidents.

In the future, Shenzhen Power Supply Bureau will continue to focus on the direction of strategic transformation of China Southern Power Grid Corporation, focus on the application of new technologies such as “Yunda mobile intelligence”, rely on the laboratory, combine various self-developed innovative algorithms and business models of Shenzhen Power Supply Bureau with Huawei’s advanced ICT Technology, and strive to build core competitiveness in smart grid operation, industrial chain integration and energy ecological construction.
