35kV collection line cable fault location device

35kV collection line cable fault location device

1、 System Overview

The precise fault location system for distribution network lines is widely used for accurate fault location and identification of 10kV-35kV voltage level distribution network lines. Based on advanced technologies such as megawatt level high-speed sampling, Beidou high-precision timing, and precise calibration of signal phase errors, precise positioning of distribution network faults can be achieved. The core module based on artificial intelligence deep learning algorithm can automatically and quickly identify fault types, and assist distribution network operation and inspection personnel in analyzing the causes of faults and warning of hidden dangers.

2、 System architecture

The distribution network diagnostic device collects fault traveling wave signals and fault power frequency signals at high speed, uploads them in real time to the monitoring platform, and uses artificial intelligence deep learning algorithms to diagnose faults and output diagnostic results. The diagnostic results are pushed to operation and maintenance personnel in the form of alarm messages, and relevant information can be viewed in real time through mobile phone messages and web clients.

3、 Functional Features

1. High precision fault location: By installing mainline positioning devices and section positioning devices on the main and branch lines of the distribution network, faults on the lines can be quickly located, achieving a distribution network fault location accuracy of less than 100 meters;

2. Accurate fault recording and traveling wave recording: real-time high-speed sampling, accurate recording of fault current and traveling wave current, providing high-quality data for fault analysis;

3. Artificial intelligence fault recognition: The fault recognition program using artificial intelligence deep learning algorithms has a recognition rate of over 95% for fault types and a fault recognition time of less than 5 minutes;

4. Power quality monitoring and alarm: Real time monitoring of installation point current, frequency, and harmonics, synchronous calculation of three-phase imbalance of the line, and rapid alarm when exceeding the threshold range; Real time monitoring of overloaded and overloaded lines to prevent potential problems;

5. Remote data communication: The distribution network monitoring terminal adopts 4G/VPN power private network communication method to achieve local data remote transmission and communication, and can perform parameter configuration, remote upgrade and other operations on the terminal through the Dunheng Power IoT platform;

6. Environmental monitoring: Real time monitoring of environmental parameters such as overhead wire temperature, sag, dancing, vibration, and tilt.
