the application of Internet of things technology in power grid
1 Overview of the Internet of Things
1.1 The concept of the Internet of Things
In professional terms, the Internet of Things technology is a kind of network technology, which is based on the Internet and realizes the effective connection between things through this core network. Through the effective extension and expansion of the user terminal, communication and information exchange are carried out between items and items. In layman terms, the Internet of Things is to make it intelligent by implanting various miniature sensor chips on objects, and then use modern wireless network technology to achieve “communication” between people and objects, as well as between objects and objects. “Communication”.
1.2 Fields covered by IoT technology
(1) Sensor technology refers to a device or device that can feel the measurement and convert it into a usable output signal according to a certain rule. Sensor technology is a key technology used in Internet technology. It is an important communication method for obtaining information from all parties. Without sensor technology, information will not be effectively obtained, which will affect the subsequent technology applications such as information dissemination.
(2) Communication radio frequency identification technology is a comprehensive technology that integrates radio frequency technology and embedded technology. It is similar to barcode scanning technology, but it is different. It also belongs to one of the sensing methods in sensor technology… Communication radio frequency identification technology is very common in daily life, such as access control systems, automatic toll collection, vehicle identification systems, and real-time logistics tracking systems that we often come into contact with.
(3) Embedded technology is a complex technology that integrates software, sensors, integrated circuits, and electronic applications. The technical principle is a process of sorting the received information into categories. Embedded technology has a wide range of applications, ranging from electronic devices such as radios used in our daily life to satellite systems, all of which require the application of embedded technology. At the same time, he is also the basis of various derivative technologies.
2 Application of networking technology in the power grid
2.1 The technical characteristics of the Internet of Things in power grid applications
The integration of power grid systems and the application of Internet of Things technology are academically called power Internet of Things technology, which refers to the formation of different sensors between various power facilities and equipment in the power grid system, and between facilities and equipment and operators. An intelligent network.
With the rapid development of the world economy in recent years, the demand for energy continues to grow. If a strong smart grid can be established, a comprehensive intelligent control system after the combination of the Internet of Things technology and the smart grid can be fully realized. Through the use of intelligent control methods, comprehensive intelligent management and control of power generation, transmission, transformation, distribution, power consumption and dispatching in the grid system can be achieved to achieve safe, efficient, comprehensive and energy-saving management effects. The Internet of Things technology, as the foundation of a strong smart grid, through its application and promotion in the grid, real-time monitoring of the state grid, substations, distribution lines, user usage, and power plant operation status, etc., to find problems in a timely manner and Carry out emergency repairs, reduce the accident rate, and truly realize the comprehensive intelligent control of the power system and the exchange of information.
3 Application and future development direction of Internet of Things technology in the power grid
Electric power companies have also actively carried out the coverage of the power communication private network, realized that some production sites and business sites were connected to the Internet of Things, upgraded the power distribution automation work system, optimized customer service, and improved office telephone, metering, emergency lighting and other services, making The Internet of Things is truly fully utilized and applied from the inside to the outside. The effective integration of today’s Internet of Things technology and power network system not only meets and facilitates people’s demand for electricity, but is also an innovation for power companies. The application of the Internet of Things technology to the grid system is conducive to the optimization and upgrading of the transmission technology network, making it the main communication means of the distribution network, and can effectively improve the transmission and communication capabilities of the basic network, and ensure the reliable and stable operation of the transmission and communication network.
