With the rapid development of the Industrial Internet of Things (IIoT) technology, more and more traditional industries are beginning to realize the importance of digital and intelligent transformation. In the field of power distribution equipment, the application of Data Terminal Unit (IoT Cellular Modem) has become a key technology driving this transformation. This article will delve into the application of IoT Cellular Modem in power distribution equipment, helping traditional industries to better understand its importance and value.

I. OVERVIEW OF IOT CELLULAR MODEM

IoT Cellular Modem, known as the Data Terminal Unit, is a type of device in a data communication system. In the context of power distribution equipment, IoT Cellular Modem specifically refers to a terminal device used for remote monitoring, data acquisition, and communication. It integrates functions such as communication, data acquisition, and remote management, enabling real-time data interaction with power distribution equipment through wireless communication technologies like GPRS, WIFI, 3G/4G.

1. Fault Detection and Localization

Faults in power distribution systems are often difficult to locate and troubleshoot quickly, causing significant challenges for maintenance personnel. IoT Cellular Modem devices can monitor the operating status of the power distribution system in real-time and conduct prompt fault detection and localization upon discovering abnormalities or faults. Through information coordination between the master station and the terminal, the commissioning of the power distribution automation system can be achieved, significantly reducing fault handling time and improving fault repair efficiency.

2. Real-time Monitoring and Control

IoT Cellular Modem devices can be installed in key locations such as ring main units, distribution switch stations, distributed power access points, and user-side substations, enabling real-time monitoring and control of these equipment. Through remote monitoring, maintenance personnel can obtain real-time information about the operating status, power data, and other information of power distribution equipment, ensuring the normal operation and safety of the electrical system. At the same time, IoT Cellular Modem supports remote parameter settings, program upgrades, and other functions, facilitating equipment management and maintenance.

3. Improving Operational Efficiency and Reliability

The application of IoT Cellular Modem devices not only improves the operational efficiency and reliability of power distribution equipment, but also reduces maintenance costs. Through real-time monitoring and fault detection, maintenance personnel can promptly discover and resolve potential issues, preventing equipment failures that lead to production interruptions. Additionally, IoT Cellular Modem supports multiple online modes, such as always-on, module shutdown during idle time, and standby mode during idle time, to meet the needs of different application scenarios.

4. Integration and Management of Distributed Energy

With the development of distributed energy, more and more distributed power sources are being connected to the power distribution network. IoT Cellular Modem devices can be installed at distributed power access points, enabling monitoring and control of distributed power sources. By monitoring key parameters such as generation output, voltage, and current in real-time, the coordination between distributed power sources and the power distribution network can be ensured. Furthermore, IoT Cellular Modem supports communication and collaboration with other smart devices, enabling intelligent management of distributed energy.

III. CASE STUDY OF IOT CELLULAR MODEM APPLICATION

Taking State Grid Qingyang Electric Power Supply Company as an example, the installation of IoT Cellular Modem devices has enabled remote remote-control automation of ring main units. Once a fault occurs in the line, the automation system can locate the fault segment within 30 seconds and remotely isolate the fault segment and restore power supply to the non-fault segment through remote control by dispatch center staff. This application has significantly reduced fault handling time, alleviated user inconvenience caused by power outages, and improved the reliability and user satisfaction of power supply.

The application of IoT Cellular Modem in power distribution equipment presents an opportunity for digital and intelligent transformation in traditional industries. Through functions such as real-time monitoring, fault detection and localization, improvement in operational efficiency and reliability, and integration and management of distributed energy, IoT Cellular Modem devices provide powerful support for the operation and management of power distribution equipment. In the future, with continuous technological advancements and the expansion of application scenarios, the application of IoT Cellular Modem in power distribution equipment will become more extensive and in-depth.
