In modern society, electricity, as the support of infrastructure, plays a vital role in the country's economic development and the improvement of people's living standards. However, with the continuous expansion of the power grid, the safe and stable operation of transmission lines is facing more and more challenges. In order to ensure the safe and stable operation of the power grid, it is particularly important to prevent potential failures. Hengfeng Intelligent Technology will introduce a transmission line monitoring device HFP-GZS2000 using traveling wave measurement technology to improve the accuracy of fault location and line inspection efficiency.
1. Introduction to traveling wave measurement technology.
Traveling wave measurement technology is a new type of transmission line monitoring device, the main feature of which is to collect the power frequency fault signal and traveling wave fault signal near the line fault point in real time through the distributed installation of monitoring terminals on the transmission line wire. These signals are sent back to the back-end data center through wireless methods such as 4G and 5G, and after comprehensive analysis by the data center, the fault point can be quickly and accurately determined according to different fault characteristics.
2. Advantages of traveling wave measurement technology.
1.Improve the accuracy of fault location: Using traveling wave measurement technology, the fault condition of the transmission line can be monitored in real time, so as to improve the accuracy of fault location.
2.Improve the efficiency of fault inspection: By monitoring the fault signal of the transmission line in real time, the fault point can be quickly found, so as to improve the efficiency of fault inspection.
3.Intelligent identification of transient faults: Traveling wave measurement technology can also capture the traveling wave waveform of transient faults, 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.
3. Display and use of diagnostic results.
The diagnostic results of the traveling wave measurement technology are displayed on the web and sent to the user via SMS. This method not only facilitates users to understand the real-time status of transmission lines, but also helps to repair faulty lines in time to ensure the safe and stable operation of the entire power grid.
IV. Conclusion. In short, the transmission line monitoring device using traveling wave measurement technology can effectively prevent potential faults and ensure the safe and stable operation of the power grid.
