An intelligent distributed dtu power distribution terminal and its control method

Abstract

The invention belongs to the field of electric power technology, and discloses an intelligent distributed DTU power distribution terminal and a control method. The measurement and control module realizes the monitoring of the switch; the communication module is used to realize the communication between the user's control information and the single-chip computer through the USB interface; fault location The module can realize the positioning and collection of all fault information in the line in the unit; the busbar protection module realizes the trip operation when the busbar is abnormally blocked. The DTU power distribution terminal of the present invention adopts a distributed structure and has a strong configuration function, which can meet the needs of DTU equipment to implement control lines, and realize the recording, storage, and transmission of various data, and can monitor and protect power distribution lines and isolate faults unit, but also to ensure the normal operation of the system in the event of a line failure. At the same time, the present invention can satisfy the real-time performance and reliability of the device for sending short messages in the distribution network by being provided with the communication module, and promote the normal operation of the power system.

Description

technical field [0001] The invention belongs to the technical field of electric power, and in particular relates to an intelligent distributed DTU power distribution terminal and a control method. Background technique [0002] At present: the data transmission unit DTU is a wireless terminal device specially used to convert serial data into IP data or convert IP data into serial data and transmit it through a wireless communication network. It has a wide range of applications in power systems. DTU belongs to the distribution network The monitoring device in the distribution network is conducive to the realization of distribution network automation, and it has the functions of monitoring and protecting the switch. At the same time, it combines the substation to monitor, find and identify various faults on the line, and isolate the faulty area from the entire distribution network system. However, the actual power distribution environment is very complex, and the entire distrib...

AI Technical Summary

Problems solved by technology

[0004] (1) The actual power distribution environment is very complex, and the entire distribution network is faced with various disturbances and emergencies. Therefore, DTU equipment often has power outages due to this, and continuous power supply cannot be performed, resulting in the inability to monitor;

[0005] (2) With the development of wireless network technology and computer technology, the device for sending short messages of DTU equipment in the distribution network cannot meet the requirements of real-time, reliability, and information volume
