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-DSCDistributed Overhead Transmission Line Fault Online Monitoring System has emerged as the solution. It 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 “smart stethoscope”，real-time perceiving the line health status, issuing second-level alarms and accurately locating faults when they occur, transforming the traditional “passive emergency repair” into “active early warning and rapid response”，greatly enhancing the reliability, safety and economy of power grid operation.

II. Core Technical Principles

TLKS-PIMG-DSCDistributed Overhead Transmission Line Fault Online Monitoring System is based on the analysis of power system fault characteristics, adopting innovative distributed fault location technology:

• Intelligent Sensing Acquisition: The line fault location device is directly installed on the conductor, using inductive power acquisition technology to obtain working power from line current, eliminating the need for external power supply and enabling continuous and 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: Transmits collected data to the background data center in real time via wireless communication methods such as 4G/5G
• Cloud Intelligent Analysis: The monitoring server runs 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 confirm the fault occurrence interval based on power frequency fault current characteristics
• Precise Location: Implement traveling wave ranging within the fault interval to achieve meter-level precise location of the fault point
• 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 Identification: Accurately distinguish between lightning strike faults and non-lightning strike faults
• Lightning Strike Type Analysis: Even when no tripping occurs, it can identify different lightning strike types such as lightning strikes on lightning conductors, transmission towers and conductors
• Fault Cause Analysis: Assist in judging the root cause of faults based on waveform characteristic 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
