Industry status

At present, China's power system has built the world's largest backbone communication network with optical fiber as the communication technology, but the distribution network of the network's peripheral nerves ­,

Massive equipment needs to be monitored or controlled in real time. It is difficult to fully cover optical fiber, with high cost, long time and difficult maintenance (150000/KM). With the rapid development of large-scale

distribution automation, advanced metering, integrated energy and other businesses, the communication demand of various power terminals has exploded. It is urgent to build a safe, reliable, flexible and two-way

interactive distribution communication network. Relying on the three application scenarios of 5MBB, URLLC and mMTC and the 5G network slicing technology, a 5G power private network can be built to seamlessly cover

the transmission, transformation, distribution and use of various business scenarios, provide high-intensity security isolation and customized resource assurance, and better support the typical business applications of

smart grid in the aspects of ubiquitous access, security, reliability and controllability, Promote the transformation of energy from extensive management to refined management, and implement the core strategy of clean

energy substitution and electric energy substitution.

For all kinds of power equipment, there are two ways to realize 5G communication: external 5G gateway and built-in 5G module. The direct built-in 5G module will be the mainstream way to realize 5G communication of

all kinds of power distribution equipment due to its high reliability, strong security, small size, easy integration and other advantages.

Runbo wireless module enables smart grid

Runbo 5G module and LTE Cat 1 module are embedded in intelligent distributed power distribution terminals, intelligent DTUs, load management control terminals, distributed acquisition and control terminals,

concentrators, intelligent meters, patrol robots, unmanned aerial vehicles, high-definition cameras, line fault indicators, mobile operation terminals, intelligent helmets, individual operation terminals and other power

industry equipment and equipment, It provides an optimal solution for the "last kilometer" wireless access communication coverage of the distribution communication network.

Smart grid

Four application scenarios of smart grid

The full service type of "generation, transmission and transformation allocation" of the power grid is rich. 5G can achieve full coverage of application scenarios by virtue of its three major technical features and unique network slicing technology. At present, the industry has studied and implemented four application scenarios of 5G in smart grid.

The first is differential protection, which uses 5G less than 1ms ultra-low delay characteristics to replace optical fiber with 5G, which can greatly reduce the deployment of optical fiber, reduce the deployment difficulty, and achieve cost reduction and efficiency increase. The second is unmanned inspection. Using 5G up to Gbps wide bandwidth, in substation robot inspection and other scenarios, the use of 5G unmanned aerial vehicles can reduce labor costs and security risks while greatly improving inspection efficiency, and can real-time return high-definition video. The third is advanced metering, which makes use of the 5G connection characteristics to connect a large number of smart meters, and ultimately provides users with personalized needs such as smart electricity.

Fourth, network slicing, which is a new technology unique to 5G, can create a customized industrial private network for the power industry, better meet the security, reliability and flexibility requirements of power grid business, and achieve differentiated service assurance, thus improving the autonomy and controllability of power grid enterprises for their own business. 5G slicing technology can give priority to the protection of high priority power business, and meet the needs of emergency support business through flexible slicing resource allocation when necessary.
