With the continuous advancement of the digital transformation of the power industry, hundreds of millions of power equipment have the need for networking. The power industry urgently needs to find a communication method with low latency, high security, and good economy. Commercial use of 5G brings new solutions to power communications.
Compared with 4G, 5G has a faster transmission rate, a larger transmission volume, and the ability to connect more devices. In addition, 5G network slicing technology can provide differentiated communication services according to the needs of different users, and has broad market prospects in vertical industries such as energy and power.
"In the past two years, under the guidance of national policies, various regions have carried out 5G power application exploration, ranging from 5G application testing to typical services such as distribution network differential protection, precise load control, power consumption information collection, robot/drone inspections, etc. , Went to the State Grid Shandong Qingdao 5G Smart Grid Demonstration Zone and the Southern Grid Guangzhou Pearl Bay 5G Smart Grid Comprehensive Demonstration Zone to verify the feasibility of 5G carrying power services in terms of business carrying capacity, safety, and operational stability.” Beijing Zhong Deng Wei, general manager of FibrLINK Communications Co., Ltd., said in an interview with a reporter from China Electric Power News.
Wu Peng, director of the Power Communication Network Technology Laboratory of the State Grid Corporation of China, and the head of the power wireless communication and edge computing technology of the Global Energy Internet Research Institute Co., Ltd. ("Joint Research Institute") The application of the system is divided into three phases: "can be used-dare to use-easy to use". "Usability" refers to verifying whether advanced technical indicators such as 5G low latency and large bandwidth can meet the high real-time and highly reliable communication requirements of the power system. "Dare to use" is to solve the problems of 5G network security, delay certainty, communication reliability, and network visibility and controllability, and form an overall solution for the power business 5G network bearer, and dare to hand over the business to the 5G network bearer. "Easy to use" means that on the basis of "dare to use", the power business is optimized for network characteristics, while at the same time, the cost of the industrial chain such as chip modules and operators' tariffs are greatly reduced, and a feasible business model is established to build 5G power with operators. Virtual private network, expand the scale of application, and finally realize the "public network as a private network", and has good economic and technical benefits.
