The State Grid Corporation proposes to initially build the ubiquitous power Internet of things by 2021. The power distribution field is in the main battlefield of the ubiquitous power Internet of things construction due to its large amount and wide range, and is facing enormous challenges and opportunities. In order to better promote the application of ubiquitous Internet of Things technology in power distribution field, China Electric Power Research Institute Limited (CAPES) and China Electric Power Enterprise Federation Science and Technology Development Service Center jointly held the 2019 (3rd) China Distribution Technology Summit Forum in Beijing from June 26 to 27. The theme of this forum is "Explaining the architecture of distribution Internet of Things, Promoting the high-quality development of energy interconnection". The system research and discussion of distribution Internet of Things are carried out.

Vigorously Promote the Construction of Ubiquitous Power Internet of Things

According to the strategic goal of the State Grid Corporation to build a world-class energy Internet enterprise and support the construction of "three types and two networks", the Chinese Academy of Electrical Sciences has taken the lead in the research and development of the distribution Internet of things. From the system architecture, communication protocol, software function module to security protection scheme, it has systematically carried out in-depth research and development, and has made full efforts to fight with partners. A new generation of intelligent distribution terminal based on home-made core is built, and the micro-application control center of distribution Internet of Things and the terminal APP verification platform are built.

The Chinese Academy of Electrical Sciences has made great efforts to build a new generation of intelligent distribution terminal. The technology of distribution Internet of Things represented by intelligent distribution terminal has made significant breakthroughs, realized the deep integration of traditional industrial technology and Internet of Things technology, and promoted the transformation and upgrading of distribution network technology. "At present, the research and development achievements have been successfully transformed. Seven units in Shandong and other provinces have carried out pilot construction and application of products, which has improved the lean management level of distribution network and promoted the technological progress of related industries." Zhao Peng, general manager of the Chinese Academy of Electrical Sciences, said that it is of great significance to support the construction of the State Grid Corporation's ubiquitous power Internet of Things.

In order to vigorously promote the construction of the ubiquitous power Internet of Things and accelerate the technology landing and sharing of the distribution Internet of Things, the Chinese Academy of Electrical Sciences jointly initiated the establishment of the "China Intelligent Power Distribution and Internet of Things Innovation Alliance" to integrate the industry with the ITU Science and Technology Development Service Center and the China National Research Institute of Electric Power (Beijing) and other units. Resources, build public resource platforms, promote technological innovation and industrial upgrading of distribution, establish intellectual property conversion platforms and promote market applications, and strive to build an inclusive, open, shared and cooperative industrial ecosphere.

"Distribution Internet of Things" as a "ubiquitous power Internet of Things" landing practice in the field of distribution, to achieve the perfect integration of the Internet of Things and distribution network. This year, the State Grid Corporation plans to build the first demonstration zones in Tianjin, Shanghai, Qingdao, Nanjing, Suzhou, Hangzhou and other places. The construction of the Internet of Things (IOT) is also in full swing all over the country in order to realize the large-scale engineering application of key technologies of the distribution IOT and the application and promotion of typical scenarios. The vast number of power customers to provide high-quality services for industry users to provide accurate information.

Transforming the Research and Development Achievements of the Distribution Internet of Things to the Ground

"Distribution Internet of Things not only enables interconnection of power facilities, but also greatly changes the lifestyle of every citizen and promotes sustainable urban development. Hangzhou Demonstration Zone is the first pilot area of the State Grid Corporation for the future distribution of the Internet of Things. Next, Zhejiang Province will continue to improve and promote this technical framework. Chen Lei, head of Distribution Department of equipment management department of State Grid Zhejiang Electric Power Co., Ltd., is full of confidence in the future.

In 2019, Zhejiang Electric Power Company will be based on the proven construction model of the Internet of Things in the Hangzhou Demonstration Zone. Hangzhou Bay will be widely used in the provincial comprehensive demonstration zone of the Internet of Things (including the eastern New Town of Ningbo, Shaoxing Binhai New Town, Mogan Mountain of Huzhou, Dachen Island of Taizhou), the county-level demonstration of intelligent energy in Meishan, Ningbo, and the Guangyuan of Internet in Wuzhen. Regional demonstration is widely applied.

Hangzhou Power Supply Company, as one of the first batch of ground practice units of the State Grid Corporation's "Internet of Things for Distribution", actively promotes the construction of Xiaoshan Qianjiang Century City Distribution Internet of Things Demonstration Zone, and actively implements "cloud-pipe-edge" from the production reality, aiming at solving the professional pain points and difficulties of distribution network operation and maintenance, user service, etc. "End-to-End" Distribution Internet of Things Architecture System, exploring and practicing the technology of distribution Internet of Things with TTU as the core, deepening the information connection and business integration of operation and distribution, realizing full state control of distribution equipment, full penetration of business process, and online, transparent, mobile and intelligent distribution business and information processing. To comprehensively improve the management level of operation and maintenance of distribution network and the level of high-quality power supply services.

In addition, the integrated demonstration project of the Internet of Things in Wuzhen, Jiaxing, has been listed as one of the eight key park-level demonstration projects of the State Grid Corporation, and a "ubiquitous Internet of Things" technology exhibition hall has been constructed. As the main window for the State Grid Corporation's power Internet of Things technology to show to the outside world, this year around the 2.3 square kilometer Wuzhen Summit site area, the State Grid Corporation has constructed a data fusion, open sharing, flexible and controllable Park energy Internet ecosphere. To promote the construction of digital city with energy data, to serve people's livelihood, and to form "Wuzhen Experience" which can be used for reference, replicated and popularized.

In order to help build a smart city in Jiangbei New Area of Nanjing, Jiangsu Province, and build a demonstration area of distribution Internet of things in Jiangbei New Area, Nanjing Power Supply Company of National Grid, guided by the development needs of green smart city, realizes the panoramic management of data, transparency of operation status, intellectualization of diagnosis and decision-making and rapid service response, and promotes the distribution network from traditional transportation. Change from inspection mode to intelligent operation mode.
