Application of 4G 5G edge computing gateway in power grid

The 4G 5G edge computing gateway is a kind of core equipment, which is responsible for data exchange, data processing and other functions. It uses edge computing technology to perform preliminary filtering and processing on the gateway. It also sends critical security information to the monitoring platform, thereby improving the processing efficiency of information. Efficiency, but also faster warning of danger. With the rapid development of Internet of Things technology, substations have become an increasingly significant part of the smart grid. However, with the number of sensors and the use of intelligent inspection robots, the amount of data transmission in the power system is also growing rapidly. If all data is transmitted to the cloud for processing, it will cause security risks such as increased delay, inability to process in time, and inability to detect in time. Edge computing gateways have high transmission rates and low latency.

Features of Edge Computing Gateways
1. Low latency: By processing data in real-time, response time is reduced.
2. Low cost: Use edge devices to filter, calculate and analyze data, reduce the amount of data transmission in the backbone network, and reduce network bandwidth requirements, thereby reducing data processing costs and device energy consumption.
3. High reliability: The edge device has its own computing power, and even if the upper data processing center fails, it will not have any impact on the normal operation of the user.

Edge computing is a method proposed to solve the problems associated with cloud computing. At present, cloud computing centrally places servers in a data center. Data must first be transmitted to the data center before centralized processing. However, due to the increasing number of terminals, the cost of data transmission is getting higher and higher, and the problem of delay is becoming more and more prominent. The edge computing gateway is deployed on the device side, that is, adding storage and processing functions, thereby reducing data transmission, reducing delay, and reducing system overhead. In addition, the use of 5G edge computing gateways can reduce the risk of data leakage due to the leakage of private data to the cloud.

By converting protocols, the Alotcer 5G edge computing gateway enables information exchange between networks. On the one hand, edge computing is used to improve data computing performance; on the other hand, 5G is used to improve information transmission efficiency.

Application of edge IoT gateway in power grid
In the transmission of the power grid, the substation plays a very significant role. It exchanges voltage and current in the power grid and transmits them to the high-voltage power grid.

With the continuous development of the power system, the data, video surveillance, security information, and other information in the power system are also increasing. Substations are generally located in sparsely populated places. Substation personnel must always pay attention to all corners of the substation in order to ensure its safety. According to the business requirements of the power market, it can be divided into intelligent power distribution, negative control, multi-connection low-voltage meter reading, distributed access, large-bandwidth inspection machines, emergency communication, etc.; using the characteristics of 5G IoT gateways can collect to the edge computing center and upload it to the main control station according to business requirements.
