Lu Haiwei, Deputy General Manager of State Grid Liaoning Electric Power Co., Ltd. and General Manager of Dalian Power Supply Company

Chairman Kou Wei emphasized at the company's second quarter work meeting in 2019 that the construction of a ubiquitous power Internet of Things is the core task of the company's new strategy implementation. Liaoning Dalian Power Supply Company fully implemented the company's deployment, accelerated the implementation of the strategic goal of "three types and two networks, world-class", and quickly promoted the construction of a ubiquitous power Internet of Things.

Combined with regional characteristics

Be a good role model

Dalian is the international shipping center of Northeast Asia and the permanent host city of the World Economic Forum Summer Davos. Accelerating the construction of ubiquitous power Internet of Things is of great significance to the regional economic development.

As the company's urban energy Internet comprehensive demonstration unit, Dalian Power Supply Company attaches great importance to the construction of urban energy Internet comprehensive demonstration projects. It deeply combines the characteristics of the Dalian area, starts from the basics, faces the forefront of energy and power technology, faces the front line of power grid production and operation, faces the transformation and upgrading of enterprises, and improves quality and efficiency. It improves power grid efficiency, strengthens lean management, cultivates emerging businesses, and expands value-added services, and solidly promotes the implementation of the company's "three types and two networks, world-class" strategy.

Dalian Power Supply Company comprehensively sorted out the problems in funding, technology, data, etc. in the early stage of the construction of the comprehensive demonstration project of urban energy Internet, the project construction plan and the project planning. On the basis of realizing six functions such as active repair and simultaneous line loss management, it expanded the application of 10 technical applications such as the application of power status perception technology for important customers, regional energy Internet application, line loss assistant, and business expansion assistant. Actively optimize the power business environment, serve local economic construction, give full play to the advantages of power grid enterprises, and serve the construction of smart transportation and smart cities.

This year, under the overall arrangement and guidance of State Grid Corporation of China and State Grid Liaoning Electric Power Co., Ltd., the construction of ubiquitous power Internet of Things of Dalian Power Supply Company has been fully launched. The demonstration area includes Dalian Development Zone, Donggang Business District and Jinzhou Ershilibao, with a power supply area of ​​about 106.5 square kilometers and a power supply population of about 350,000. It includes A+, B, and C power supply areas, involving 175 10 kV lines and 2,463 10 kV distribution transformers.

Dalian Power Supply Company will present a panoramic view of the construction achievements of the ubiquitous power Internet of Things at the Davos Conference this summer and at the end of the year, and will comprehensively build a world-class energy Internet enterprise.

Relying on power grid big data

Promoting intelligent services

Through the construction of a comprehensive application management platform for distribution network big data, Dalian Power Supply Company has achieved multi-regional distribution automation coverage and integrated application extension to prefectures and counties, greatly improving the grid's control and large-scale optimization of resource allocation capabilities.

Dalian Power Supply Company, based on the integration of marketing and distribution, relies on the support of the full-service data center to realize the intelligentization of power supply service command business. The core content is to promote data integration, carry out digital process micro-applications and quantitative assessments, and build a lean management system of quantitative analysis, so as to transform the results of various professional work from the past "unclear and inexplicable" to intuitive visualization, forming a digital management model. At the same time, according to the requirements of the construction of the ubiquitous power Internet of Things, in accordance with the design concept of the Internet of Things architecture of the four-layer system of perception layer, network layer, platform layer, and application layer, and fully consider the reusability of the results, it is planned to carry out deeper exploration in the expansion and application of distribution network big data, intelligent mobile applications, precise positioning services, comprehensive information security management and control, business visualization, etc., to promote the construction of the ubiquitous power Internet of Things.

Dalian Power Supply Company will collect all kinds of terminal data in real time through intelligent transformation of all types of terminal equipment at the perception layer in the pilot area, including the application of large-capacity backbone optical transmission network, medium and low voltage high-speed power line carrier, power wireless private network, Beidou satellite communication, 5G and other hybrid networking technologies to build a prefecture-level integrated communication network to achieve full-process holographic perception of IoT terminal information. At the same time, based on the construction of a full-scenario network security protection system, all types of terminals in all links of the power system will be interconnected in the pilot area, and real-time visual interaction between humans and machines will be achieved, so as to improve the holographic perception, ubiquitous connection, open sharing and integrated innovation capabilities of prefecture-level power supply companies.

Make up for the "shortcomings" and check the deficiencies

Lay a solid foundation and focus on innovation

Dalian Power Supply Company has provided convenient and efficient support for production, operation, management and other businesses by applying advanced technologies in the energy field, but it still has shortcomings compared with the goal of building a first-class energy Internet enterprise in China. The main problems are: the collection of power grid operation data is not comprehensive, the quality is not high, and the level of data application is low; the barriers between existing business systems are obvious, the real-time nature of data sharing is not strong, and the value of data assets needs to be explored; the communication access network coverage is not deep enough, the bandwidth is insufficient, the terminal collection monitoring management is missing, and the level of security control is not high.

To accelerate the construction of ubiquitous power Internet of Things, Dalian Power Supply Company will carry out work in the following aspects: First, improve the construction plan of the comprehensive demonstration project of urban energy Internet; second, actively apply for pilot construction to State Grid Corporation of China and State Grid Liaoning Power, and strive to undertake more pilot project construction tasks; third, organize various professional departments to carry out feasibility study preparation and review of projects related to the comprehensive demonstration project of energy Internet; fourth, strengthen communication and exchanges between business departments and technology manufacturers, carry out technical research related to ubiquitous power Internet of Things, and promote new technology research and engineering application; fifth, promote the construction of distribution network big data projects and the in-depth application of power supply service command system, and strive to achieve results in the pilot area as soon as possible.

Dalian Power Supply Company will give full play to the advantages of power grid enterprises, innovate and apply advanced technologies in the energy field, further accelerate the construction of urban energy Internet, and comprehensively assist the development of smart cities.
