With the research and construction of smart grids, the requirements for the construction of dedicated wireless communication networks for electric power are becoming more and more stringent. For example: wider coverage requirements, covering 10kV or even 220 / 380V power grid; higher communication bandwidth requirements, which will reach tens of trillions or even hundreds of megabytes; shorter data transmission delay, which will be shortened to the order of milliseconds; real-time Higher performance and reliability requirements. In addition, communication equipment needs to operate stably in a more demanding environment. These requirements have prompted wireless mesh to gradually become the mainstream technology of wireless communication systems in smart grids. Strix is ​​a global leader in high-performance wireless Mesh networks. Its advanced wireless Mesh products are widely used in the smart grid field in the following areas: Application in Digital Monitoring of Transmission Line Due to the limitations of various technologies and conditions, real-time information on high-voltage transmission lines or ultra-high-voltage transmission lines cannot be transmitted back to the monitoring center in real time. If all kinds of signals are intercepted into pictures and packets by GPRS or similar methods and transmitted back to the monitoring center, there are shortcomings such as low real-time performance and poor judgment of the overall environment. It is easy to delay and misjudge the problems of judging towers and lines. Seriously reduced the safe operation index of power grid towers and lines. By setting up the Strix wireless Mesh network along the power line, relying on its low latency and high bandwidth performance after multi-hop to significantly reduce the construction of optical fiber networks, the data signals of substations and power facilities, and video signals of video surveillance systems are carried out. Real-time backhaul provides guarantee for the safe operation of large power grids. Application in digital substation By setting up a Strix Mesh wireless network and using the redundancy mechanism and rerouting function provided by it, when a certain point of the network fails, it will not affect the entire network. This function fully guarantees the monitoring of various status information of the substation and helps The intelligent fault diagnosis and location of the operation and maintenance personnel can reduce the "three errors" accidents and fully guarantee the reliability of the digital substation system. Application in Disaster Tolerance Early Warning and Guarantee System In recent years, domestic natural disasters have occurred frequently, which puts a severe test on the power grid and its communication system. The rapid networking and rapid self-healing characteristics of the Strix mesh network are combined with other related equipment to form a perfect emergency communication solution, so that In a sudden state, the main communication of the main fault line is quickly restored, the repair of the fault point, the liaison between the scene and the command center, the communication of the dispatch and command of the repair spot, and the multimedia data collection of the fault point. Application of Digital Comprehensive Monitoring System in Distribution Network The distribution network is more closely related to the people who use electricity, and it needs continuous and efficient operation. Utilize the automatic link repair performance of Strix mesh, set up a wireless Mesh network and optical fiber to form a double backup, avoid "information islands", real-time online monitoring of distribution lines, short circuit faults, ground faults, temperature, switch status and other information, to achieve digital monitoring . Application in intelligent electricity service system Using the diversity and flexibility of Strix Mesh networking combined with smart meters to provide value-added services to consumers, not only can users at different times of the day and the electricity consumption of each appliance at a glance, help users according to the difference between peak and valley time Electricity price, electricity is used more economically. At the same time, for the power grid company, it can also understand the user's power consumption status in real time, monitor and collect the user's power consumption information in real time, realize the optimal configuration and utilization of electrical energy, and improve the reliability of the grid operation and energy efficiency. The application of Mesh technology in the smart grid not only improves the internal work efficiency of grid companies, but also improves the economic and social benefits of the entire grid company. Mesh technology has broad application prospects in the smart grid.
