Transmission Line Distributed Fault Location System

I. Product Description:

As a critical component of the power system, the operational status of transmission lines directly impacts the safety and stability of the entire grid. However, due to factors such as long line lengths, complex environments, and external interferences, transmission lines often face the risk of faults. Traditional fault investigation methods primarily rely on manual inspections, which not only consume significant human and material resources but are also inefficient. Therefore, our company's Transmission Line Distributed Fault Location System was developed to address these challenges.

II. Working Principle:

The Transmission Line Distributed Fault Location System innovatively incorporates advanced inductive energy harvesting technology, enabling continuous autonomous operation without external power sources. This breakthrough significantly reduces the system's installation complexity and long-term maintenance costs. The system features high-precision data acquisition capabilities, accurately capturing power frequency fault currents and fault traveling wave current waveforms on the line. These data serve as the "fingerprint" of the line's health, providing a solid data foundation for accurately assessing the line's operational status and fault location. The collected critical data is transmitted in real-time to the backend data center via a highly stable 4G network channel, ensuring timeliness and accuracy in data delivery and enabling remote monitoring and analysis. Maintenance personnel can easily access the data center via the Internet to observe dynamic charts and data analysis of key parameters such as line currents in real-time. The system intelligently identifies potential anomalies in the line, achieving comprehensive monitoring of line health. Upon detecting any signs of a fault, the system immediately initiates an emergency response mechanism, automatically generating detailed fault reports and precisely marking fault location information, which is promptly sent to the maintenance team through predefined channels. This process significantly shortens the time from fault detection to response, providing maintenance personnel with valuable "golden repair time," effectively enhancing the efficiency and accuracy of grid fault handling, and safeguarding the stable operation of the power system.

III. Product Functions:

1. Determine the fault section based on power frequency fault current

2. Implement precise traveling wave fault location within the determined fault section

3. For transmission lines with complex network structures, install distributed fault diagnosis devices at branch points to divide the complex network into simpler single-line structures

4. Identify the causes of faults, enabling discrimination between lightning and non-lightning faults. It can also identify lightning strikes on shield wires, towers, and conductors in cases where no tripping occurs

IV. Technical Parameters:

1. Ambient Temperature: -40℃ to +85℃

2. Relative Humidity: 0 to 100% RH

3. Atmospheric Pressure: 86 kPa to 106 kPa

4. Storage Temperature: -40℃ to +85℃

5. Wind Speed: 0 km/h to 100 km/h

6. Line Load: The system's coupling energy harvesting operates normally within a current range of 20 to 1000 A

7. Compatibility: Capable of withstanding 500 kV strong electric and magnetic fields, with reliable and stable electromagnetic compatibility

V. Summary:

The Transmission Line Distributed Fault Location System, with its intelligent and networked advanced technology, establishes a comprehensive monitoring and real-time fault response system for transmission lines. This system not only excels in fault detection and precise location but also provides solid data support and technical backing for the safe and stable operation of the power system. With the rapid development of smart grid construction, this system will undoubtedly play an increasingly critical role in future power networks, driving grid management toward greater efficiency and intelligence.
