shenzhen dinsee smart technology co., Ltd. Introduce you to our transmission line distributed fault monitoring system of double-end ranging mode can achieve what effect:
It is evident that the distributed fault monitoring system for transmission lines can accurately identify the faulted section of a transmission line after a fault occurs and can recognize lightning strikes/various types of non-lightning strikes faults after the line has tripped.
Through the deployment of multiple traveling wave current monitoring terminals on the conductor real-time collection of line operation in the process of industrial frequency and traveling wave fault signals. In addition to locating faults, the distributed fault monitoring system for transmission lines also has a strong fault type recognition capability, which can accurately recognize lightning strikes and various types of non-lightning faults after the line trips. This capability is essential for developing targeted fault repair strategies and preventive measures.
The above functions are what can be achieved by the double-ended ranging mode of the distributed fault monitoring system for transmission lines.
I. Advantages of the double-ended ranging model
The double-end ranging mode utilizes the traveling wave ranging principle by installing monitoring devices at both ends of the line, and calculates the location of the fault point by detecting the time difference between the arrival of a traveling wave at both ends. This mode is characterized by high precision and fast response, which can quickly locate the fault point and provide timely fault information to the operation and maintenance personnel, greatly shortening the fault investigation time and improving the operation and maintenance efficiency.
II. Rationalization of distributed installation methods
1. Wide coverage 2, cost savings: no need to install monitoring devices in every pole tower, greatly reducing the installation cost and maintenance costs. At the same time, the design of adding one set of device for every additional 30 kilometers not only ensures the continuity of monitoring, but also realizes the effective control of cost. 3, flexible deployment: for the same tower line, each installation point is configured with 1 set of terminals, which not only meets the monitoring requirements, but also avoids the waste of resources. This flexible deployment allows the system to be customized according to the characteristics of different lines. III. Technical realization and reliability 1, traveling wave ranging technology: the use of traveling wave detection technology and intelligent algorithms, the system is able to accurately and quickly calculate the fault interval and distance, the whole process has a strong anti-interference ability, high measurement accuracy. 2. Highly integrated and integrated design: The monitoring terminal adopts highly integrated and integrated design with compact structure, light weight and low power consumption, which is easy to install and maintain. At the same time, the terminal is equipped with self-test and self-recovery functions, which can regularly check its own status and report it to the data center, and can recover itself in the event of a crash, thus improving the reliability of the system. Overall, with the increase in power demand and the access of renewable energy, the operational pressure of transmission lines is increasing, and the importance of fault monitoring is becoming more and more prominent. In the future, with the continuous development of artificial intelligence and Internet of Things technology, the distributed fault monitoring system for transmission lines will be further intelligentized to achieve more efficient and more efficient power protection, and help the construction and development of the smart grid.
