Transmission line trip fault location system

I. Product Overview: Equipping transmission lines with“smart eyes”

Against the backdrop of increasingly complex and large-scale modern power grids, how to quickly and accurately locate line faults and shorten power outage durations is a major challenge faced by power operation and maintenance departments. The TLKS-PIMG-DSC Distributed Overhead Transmission Line Fault Online Monitoring System has emerged as the solution. This is an efficient monitoring solution integrating distributed sensing, wireless communication, and intelligent analysis technologies, like equipping each transmission line with a 24/7 on-duty “intelligent stethoscope”，实时感知线路健康状态，在故障发生时秒级告警、精准定位，将传统的“被动抢修”转变为“主动预警与快速响应”，极大提升了电网运行的可靠性、安全性与经济性。

II. Core Technical Principles

TLKS-PIMG-DSC Distributed Overhead Transmission Line Fault Online Monitoring System is based on the analysis of power system fault characteristics and adopts innovative distributed fault location technology:

• Intelligent Sensing and Acquisition: Line fault location devices are directly installed on conductors, and use inductive power-taking technology to obtain working power from line current, eliminating the need for external power supply and enabling continuous stable operation
• Dual-Mode Data Acquisition: Synchronously collects power frequency current and traveling wave current waveform data, providing multi-dimensional data support for fault analysis
• Wireless Real-Time Transmission: Uses wireless communication methods such as 4G/5G to transmit collected data to the background data center in real time
• Cloud Intelligent Analysis: Monitoring servers run professional monitoring software to conduct in-depth analysis and processing of massive data, enabling rapid fault diagnosis and precise location

III. Core Functional Features

1. Precise Fault Location

• Interval Determination: Quickly identifies the fault occurrence interval based on power frequency fault current characteristics
• Precise Location: Implements traveling wave ranging within the fault interval to achieve meter-level precise location of fault points
• Network Adaptation: For complex network structures, devices can be installed at branch points to divide the complex network into simple single-line structures for analysis

2. Intelligent Fault Identification

• Lightning Strike Recognition: Accurately distinguishes between lightning strike faults and non-lightning strike faults
• Lightning Strike Type Analysis: Can identify different lightning strike types such as lightning strikes on ground wires, towers, and conductors even when there is no circuit breaker tripping
• Fault Cause Analysis: Assists in judging the root cause of faults based on waveform feature analysis

3. Real-Time Monitoring and Early Warning

• 7×24-hour uninterrupted monitoring of line electrical parameters
• Instant alarms for abnormal conditions (overload, short circuit, grounding, and other faults)
• Historical data storage and analysis, supporting trend prediction
