Intelligent distributed DTU power distribution terminal and control method

Abstract

The invention belongs to the technical field of power and electricity, and discloses an intelligent distributed DTU power distribution terminal and a control method. A measurement and control module is used for monitoring a switch; a communication module is used for enabling control information of a user to communicate with a single-chip microcomputer through a USB interface; a fault positioning module can realize positioning and acquisition of all fault information in a line in the unit; and a bus protection module is used for realizing tripping operation when the bus is abnormally locked. The DTU power distribution terminal provided by the invention adopts a distributed structure, has a relatively strong configuration function, can meet the requirement of DTU equipment for implementing acontrol circuit, realizes recording, storage, transmission and the like of various data, can monitor and protect a power distribution circuit and isolate a fault unit, and can also ensure that a system can normally operate when the circuit has a fault. Meanwhile, by arranging the communication module, the real-time performance and reliability of the device for sending the short message in the power distribution network can be met, and normal operation of a power system is promoted.

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
