How to build a smart substation with edge computing gateway [Copy link]

With the development of industrialization, the scale of the power grid continues to expand, and the number of power terminal devices has grown exponentially, resulting in massive data transmission and processing needs. This not only puts tremendous pressure on the server host station, but the high latency and high error in the process cannot meet the requirements of new business forms such as intelligence and automation.

To address these issues, edge computing technology can be applied to sink data processing and feedback to the edge layer. By prepending computing power to achieve regional autonomy, it not only reduces the data processing pressure of the main station system, but also reduces operation and maintenance costs and improves system efficiency. This article will briefly introduce the application of building a smart substation based on edge computing gateways.

Advantages of edge computing in smart grids

1. Low latency: Currently, more and more data business scenarios require ultra-low network latency. By deploying edge computing gateways, data analysis and computing work can be moved to the edge side, and efficient processing can be performed at the source of the data, which can effectively shorten the response time;

2. Low energy consumption: The distributed architecture of edge computing can reduce data transmission and network channel occupancy between the cloud, which not only saves broadband costs, but also alleviates network congestion, and reduces data processing costs and equipment operation energy consumption;

3. Reliability: Distributed edge devices can provide local computing and management functions for the system, ensuring the stable operation of the local system when the cloud center fails to process in time or communication fails.

4. Security: For some sensitive facilities and areas, edge computing solutions can be used to analyze and process sensitive data directly at the edge, eliminating the transmission link, improving data privacy and security, and preventing data leakage/theft risks.

Smart substation application based on edge computing gateway

The smart substation is designed and constructed based on the existing traditional substation. By deploying high-computing power edge computing intelligent gateways, it centrally collects and monitors power equipment status parameters, environmental conditions, safety monitoring perception, smart fire protection, personnel management, etc., thereby realizing comprehensive status perception, information interconnection, human-computer interaction, and intelligent operation and maintenance of the substation site.

The solution can adopt the BMG800 series edge computing intelligent gateway, which has rich data acquisition interfaces, is equipped with a high-computing industrial-grade processor, supports multiple communication methods for mutual backup, and meets one-stop access to on-site sensors/instruments/cameras/equipment, etc., to realize unmanned substation, real-time inspection, abnormal alarm, intelligent intervention and disposal, etc., effectively improving the intelligence level of the substation.

The introduction of edge computing technology will not only further strengthen the multi-directional intelligent linkage and coordination of the power supply side, grid side, load side, and energy storage side, but also meet the sustainable operation needs of low energy consumption, high intelligence, and high efficiency, and jointly help the power Internet of Things to reach a new level.
