Power Distribution Automation

The continuous growth of power load and the emergence of various new loads make users pay more attention to power quality and impose stricter requirements for energy conservation and emission reduction. More effective power monitoring and management solutions are needed to address the challenges brought by the above changes, so as to achieve sustainable, reliable, efficient, and low-consumption operation of the distribution system.

In the 5G era, 5G is deeply integrated with cloud computing, big data, the Internet of Things, artificial intelligence, and other information technologies, forming the core capabilities of the new-generation information infrastructure, becoming an important driving force for the development of digital economy, and bringing profound changes to the development of the power sector.

The new-generation power system formed by integrating new energy, new materials, new equipment with advanced sensing technology, information technology, control technology, energy storage technology, and other new technologies based on the traditional power system is highly information-based, automated and interactive. It can better realize safe, reliable, economical, and efficient operation of power grids.

Focusing on the five steps of power generation, transmission, transformation, distribution, and consumption, typical application scenarios for 5G in smart grids include intelligent distributed distribution automation, millisecond precise load control, low-voltage electricity consumption information acquisition, and distributed power supply.

Case Description

The distribution automation system is an important part of smart grids. Distribution automation is an integrated system for monitoring the operating conditions of all kinds of equipment in the distribution network in real time. It integrates distribution network monitoring and measurement, fault detection and locating, automatic control, planning, and statistical data management. The distribution automation system consists of the DRTU information acquisition layer, communication network layer, SCADA monitoring layer, assisted decision making layer, and WEB publishing layer. By adopting distributed network protection technology, relying on high-speed optical network communication, through quick decision making among DRTUs, feeder fault locating, fault isolation and power supply recovery can be realized on site, which can further reduce the scope and time of power cuts. In this scenario, communication modules can provide stable and fast communication to achieve timely and effective real-time monitoring.

Data transmission through SIM8202G-M2 enables distribution network information acquisition, processing, storage, analysis, computing, decision making, information sharing and real-time interaction with distribution network GIS, distribution network production information, scheduling automation, metering automation, and other systems. Through real-time data connection, the running status of power distribution lines can be monitored and controlled. After a fault occurs, the fault area can be quickly located and isolated, and power supply can be restored in non-fault areas, greatly improving the reliability and stability of power supply.

The deep integration of 5G technology with power energy and information will build a more secure, efficient, and green smart grid system, bringing huge economic benefits to the power sector. SIMCom’s 5G modules will also continue to evolve, enabling the 5G power industry.
