With the development of society and economic progress, the demand for electricity continues to grow, and the safe and stable operation of transmission lines, as an important channel for power transmission, is very important to ensure power supply. In order to improve the fault location accuracy and line inspection efficiency of transmission lines, the application of distributed traveling wave measurement technology in the field of transmission line positioning has gradually attracted attention in recent years. Hengfeng Intelligent Technology will introduce a transmission line positioning HFP-GZS2000 method based on distributed traveling wave measurement technology, as well as its advantages and application value.
1. Introduction to distributed traveling wave measurement technology.
Distributed traveling-wave measurement technology is a technology that collects power frequency fault signals and traveling-wave fault signals near the time of line fault in real time by installing monitoring terminals on transmission line conductors, and sends them back to the back-end data center wirelessly. This technology can realize real-time monitoring and fault diagnosis of transmission lines, so as to improve the accuracy of fault location and the efficiency of line inspection.
2. Application of distributed traveling wave measurement technology in transmission line positioning.
1.Real-time monitoring and fault diagnosis.
The distributed traveling-wave measurement technology uses high-potential acquisition of power frequency fault signals and traveling wave fault signals near the fault point of the line, and sends them back to the back-end data center through wireless methods such as 4G and 5G. Through the comprehensive analysis of the data center, the fault point can be quickly and accurately determined according to different fault characteristics, and the fault location accuracy can be improved, so as to improve the efficiency of fault inspection.
2.Intelligently identify transient fault types.
The distributed traveling wave measurement technology can also capture the transient fault traveling wave waveform, and intelligently identify whether the fault is a lightning fault or a non-lightning fault, and whether the lightning fault is a bypass or a counterattack. This helps to detect and deal with potential safety hazards in a timely manner and ensure the safe and stable operation of the power grid.
3.Diagnosis result display and notification.
The diagnostic results are displayed on the web and SMS and sent to the user, which helps to repair the faulty line in time and ensure the safe and stable operation of the entire power grid.
III. Conclusion. In short, as an advanced transmission line positioning technology, distributed traveling wave measurement technology has important application value in ensuring the stability of power supply. Through real-time monitoring and fault diagnosis, intelligent identification of transient fault types, and diagnosis result display and notification, the fault location accuracy and line inspection efficiency of transmission lines can be effectively improved, and the safe and stable operation of the power grid can be ensured.
