2. Substations further promote the safe operation and maintenance of substations and vigorously promote location services

Under the traditional management mode, the maintenance personnel of the 500kV substation of the power grid went to the wrong area, the supervision of the climbing operation was not in place, and the grounding wire was improperly operated. In order to break the shackles of traditional management, China Southern Power Grid introduced the UWB module UWB positioning solution IoT technology, and focused on the cutting-edge technology to improve the efficient, transparent, intelligent and safe management of substations.

On the basis of two-dimensional positioning, the three-dimensional management, grounding wire connection and dismantling judgment of ascending operators are realized on the substation site, combined with visual three-dimensional, electronic fence, video linkage, etc., so that the probability of human error operation, missed operation, and wrong area is 0 , greatly reduce the pressure of on-site management, improve the level of safe operation and maintenance, and further promote the digital construction of the power grid.

3. Realize the digital safety management of wind power and wind farms

As one of the most widely used and rapidly developing new energy sources, wind power is promoting the optimization of the entire energy structure. While the new installed capacity of wind power is increasing, wind farms are also facing some problems that need to be solved urgently. For example, wind farms are basically built in sparsely populated areas such as seas, mountains, and plains, and the surrounding infrastructure is poor, which makes infrastructure, equipment data communication, personnel operation safety monitoring and other aspects inconvenient, and even security risks.

The Beidou satellite positioning system is combined with the technology of the UWB module UWB positioning solution precise positioning system, and the Beidou positioning technology is used to enter the tower in the outdoor area and automatically switch to the UWB positioning technology. Indoor/outdoor positioning is seamlessly connected without switching, and the transition is smooth. In this way, high-precision positioning of operators and vehicles in the outdoor areas of wind farms and towers can be achieved, an intelligent safety control center will be established, and a location management platform that can be found, prevented, and controllable will be created to escort the digital safe production of wind farms.

The horn of the digital economy has sounded, and our company will continue to work hard to actively and deeply integrate the location data and power applications of UWB module UWB positioning solutions, continue to provide better services for the power industry, and accelerate the digital transformation of traditional power.
