Distribution Automation Terminal (DTU) - Supporting the Modernization of Distribution Networks
With the increasing widespread deployment of distribution networks, a larger range of distribution networks requires more timely and precise monitoring and control. Sometimes, distribution equipment is located in relatively remote areas, making it inconvenient for staff to visit frequently. The economic and time costs of troubleshooting and maintenance during failures are high. Therefore, distribution automation is gradually becoming popular, and the Distribution Automation Terminal (DTU) is one of the important components of the distribution automation system.
Distribution equipment has been continuously improved and innovated, and the corresponding requirements for supporting equipment have also been continuously raised. The QCD-2000 series distribution automation terminal (DTU) developed by Beijing Qingchang uses a high-performance dual-core CPU as the hardware development platform and an embedded real-time operating system as the software development platform, ensuring its stability, high performance, and ease of installation and maintenance during actual operation.
QCD-2000The series of distribution automation terminals (DTU) are currently mainly used in ring main units, small switching stations, box-type substations, etc. They achieve real-time power collection and control, fault detection, fault area location and isolation, and restoration of power supply in non-fault areas. These functions are all centered around ensuring and improving the reliability and stability of power supply. In summary, the distribution system equipped with DTU can achieve:
1. Improve power supply reliability;
2.Improve power quality;
3.Save energy and reduce losses, optimize operation;
4.Improve the management efficiency of the distribution network.
Specifically, its main functions are as follows:
1. Collect line fault information, complete fault identification, accurately inform maintenance personnel of the fault interval, eliminating the need for individual checks;
2.Achieve measurement and collection of multiple lines and various values (voltage, current, power, frequency, etc.), and directly transmit to the upper-level device;
3. Remotely receive and execute commands, capable of executing fault isolation, power restoration, sending back for verification, time synchronization, and return commands;
4. Has channel monitoring capabilities; can communicate with other systems for information exchange;
5. Can achieve self-diagnosis of equipment and self-recovery of programs;
6. Can connect to multiple power sources, automatically and seamlessly switch in when the main power source fails, and has intelligent maintenance functions for batteries;
7. Rich communication protocols, supporting currently popular protocols.
After equipping with the QCD-2000 series distribution automation terminal, it can help the upper master station system monitor the operation of the distribution network at any time and make timely and correct decisions. At the same time, this device can greatly shorten the fault handling time and reduce labor and economic costs.
