Overview of DTU Distribution Network Automation Terminal Device:
The DTU series distribution automation terminal device is a protection and monitoring terminal product developed for multi line collection sites such as ring main units and small switch stations in distribution networks.
The current and voltage acquisition of the main control unit in the DTU device adopts A/D dedicated high-speed sampling chips, and the device also uses a 32-bit MCU control chip as a high-voltage switch control device, which can quickly and stably monitor the high-voltage switch. It integrates functions such as protection, measurement, control, monitoring, communication, and motion, and has the characteristics of high integration, flexible configuration, and user-friendly interface. Widely used in radiation power supply and ring network power supply systems, it can help the system identify transient and permanent faults in the line, automatically eliminate the impact of transient faults on the line, isolate permanent fault sections, avoid long-term large-scale power outages, automatically restore power supply to non fault sections of the grid, and thus achieve distribution network automation economically and practically.
Functional characteristics of DTU distribution network automation terminal device:
1. Unified core public platform: adopting embedded real-time operating system, supporting high-speed Ethernet bus and CAN bus, with large interface capacity.
2. Diversified configuration of communication methods and protocols: hardware configuration with independent communication management module, hardware configuration supporting primary and backup interchangeability, redundant design. Software configuration supports multiple communication methods
(Ethernet, GPRS, fiber optic, etc.) and multiple communication protocols (such as GB101, GB104, MUDBUS, etc.), can communicate with multiple master stations of different levels simultaneously.
3. Flexible configuration of remote signaling, remote control, and telemetry: The number of points for the three remote functions can be configured according to engineering needs, with a truly modular design.
4. Intelligent power management: Multiple power supplies, supporting battery switching of various media and capacities, intelligent battery management (can automatically activate the battery), monitoring and displaying the output voltage and power of the operating power supply, with complete overload and short circuit functions, and online hot backup of the backup power provided by the battery.
5. Convenient maintenance function: Provides remote and local maintenance interfaces, allowing operators to perform maintenance locally or remotely from the main station. Support handheld wireless maintenance, which can be easily carried out
Debugging.
6. Flexible and convenient strategy configuration: current type DA, voltage type DA, composite type DA. The system adopts modular design to support the use of various specifications of circuits, supporting 18 circuits.
