The Twelfth Five-Year Plan of the Internet of Things defines the twelve key application areas of the Internet of Things technology, including smart grid, transportation, logistics industry, medical and health, smart home, environment and safety inspection, precision agriculture and animal husbandry, industry and automation. Control, finance and service industries, public security, defense and military, and smart cities. This article will focus on the National Twelfth Five-Year Plan, and chapters will introduce several Internet of Things applications.

The essence of the Internet of Things is to build a bridge of communication between things and things. It is an inevitable outcome of the era of multi-network integration. It extends the communication between people to people and things, things and things. Connected, intelligent and networked life will make people work and life more convenient and humane.

Smart grid

It is the intelligentization of the power grid, also known as “grid 2.0,” which is based on an integrated, high-speed, two-way communication network, advanced sensing and measurement technologies, advanced equipment technologies, advanced control methods, and advanced technologies. The application of decision support system technology to achieve the grid's objectives of reliability, safety, economy, efficiency, environmental friendliness, and safety of use. Its main features include self-healing, motivating and including users, resisting attacks, and providing electricity that meets the needs of users in the 21st century. Quality, access to various forms of power generation, start-up of electricity markets, and optimization and efficient operation of assets.

State Grid China Electric Power Research Institute: Based on the physical power grid (China's smart grid is based on the UHV power grid as the backbone of the network, the development of a strong grid of voltage level grid based on the coordination), the modern advanced sensor measurement technology, A new type of power grid formed by the highly integrated communication technology, information technology, computer technology, and control technology and the physical power grid. It is designed to fully meet the user's demand for electricity, optimize the allocation of resources, ensure the safety, reliability and economy of the power supply, meet the environmental constraints, ensure the power quality, and adapt to the development of the power market. , clean, interactive power supply and value-added services.

Compared with the existing power grids, smart grids reflect the prominent characteristics of highly integrated power flow, information flow, and business flow. Its advanced nature and advantages are mainly reflected in:

(1) It has a strong grid infrastructure and technical support system that can withstand various types of external interference and attacks, and can adapt to the access of large-scale clean energy and renewable energy, and the strength of the power grid is consolidated and enhanced.

(2) The organic integration of information technology, sensor technology, automatic control technology and power grid infrastructure can obtain panoramic information of the power grid and timely discover and anticipate possible failures. When a fault occurs, the power grid can quickly isolate the fault and achieve self-recovery so as to avoid the occurrence of a large-scale power outage.

(3) The extensive application of flexible AC/DC power transmission, network factory coordination, intelligent dispatch, power storage, and distribution automation technologies make the grid operation control more flexible and economical, and can adapt to a large number of distributed power supplies, microgrids and electric power Access to vehicle charging and discharging facilities.

(4) Comprehensive utilization of communications, information, and modern management technologies will greatly increase the efficiency of power equipment use, reduce power consumption, and make the power grid operate more economically and efficiently.

(5) Realize high-level integration, sharing and utilization of real-time and non-real-time information, display a complete, complete and detailed grid operation status map for operation management, and provide corresponding support decision support, control implementation plans and response plans.

(6) To establish a two-way interactive service model, the user can understand the power supply capacity, power quality, price status and power outage information in real time, and reasonably arrange the use of electrical appliances; the power company can obtain detailed power consumption information from users and provide them with more value-added services. .

Because the smart grid contains a lot of content, each grid and equipment manufacturer must adopt a master plan and a step-by-step implementation strategy according to the actual situation to gradually realize the smart grid.

Smart Substation

The smart substation is an advanced, reliable, integrated, low-carbon, and environmentally-friendly smart device. It takes the digitization of the entire station information, the networking of the communication platform, and the standardization of information sharing as the basic requirements. It automatically completes information collection, measurement, control, protection, measurement, and monitoring. Other basic functions, and can support advanced substations such as real-time power grid automatic control, intelligent adjustment, on-line analysis and decision making, and cooperative interaction. The key technologies involved are: smart transformers and circuit breakers, electronic transformers, and a unified information platform for substations.

Smart meter

The smart meter can realize the bidirectional measurement function under the two-way interactive power supply mode, can realize the fast response of the price under the dynamic floating electricity price, the fast switching, the electricity price real-time settlement and other functions.

Intelligent interactive terminal

The intelligent interactive terminal is a key device for realizing home intelligent power service. By using advanced information and communication technologies, it integrates monitoring and management of household electrical equipment, and collects and analyzes data such as power quality and household power consumption information. The user uses the electricity rationally, adjusts the peak-valley load of the grid, and realizes the intelligent interaction between the grid and the user. In addition, through smart interactive terminals, water and gas meters can be copied, meter reading costs for tap water and gas companies can be reduced, and users can provide value-added services such as home security, community services, and Internet services.
