Conductor Galloping Monitoring and Early Warning System

Online Monitoring Device for Transmission Line Conductor Galloping

I. Product Description:
Conductor galloping is one of the factors endangering the safe operation of transmission lines. Excessive amplitude can cause deformation of towers and other facilities, thereby affecting the stability of the power supply system. To ensure the stability of the power supply system, it is often necessary to collect data for calculation and galloping trajectory restoration. The online monitoring device for transmission line conductor galloping developed by our company can collect real-time galloping data of transmission conductors. Installing this device can effectively solve these problems and ensure the safe and stable operation of the power grid.

II. Working Principle:
The online monitoring device for transmission line conductor galloping uses wind-solar hybrid power supply for front-end equipment, maximizing the utilization of outdoor power. The system remotely collects galloping, micro-meteorological, and image data, then compresses and encodes the data digitally. Finally, it uses 4G/3G/GPRS/CDMA wireless transmission modules to send on-site data to the data monitoring center in IP packets. The monitoring center browses and observes the on-site conditions of each monitoring point in real time through the data monitoring client. Maintenance and monitoring personnel analyze and compare the galloping, micro-meteorological, image, and other data sent from the site. If abnormal early warning information appears, corresponding emergency measures will be taken immediately to ensure the safe operation of high-voltage lines.

III. Product Functions:
1. Real-time monitoring of conductor displacement, acceleration, angle, etc., combined with various sensor data for analysis and processing, data modeling, and timely diagnosis of abnormal information;
2. Equipped with micro-meteorological data collection function, which collects front-end temperature, humidity, wind speed, wind direction, etc., and combines them with conductor galloping data for analysis and processing;
3. Intelligent galloping analysis: Establish 3D parameters during initial device installation through the platform's 3D analysis algorithm. Based on the MATLAB algorithm, integrate sensor data and image data to form a three-dimensional monitoring system for the entire monitored line;
4. Real-time video browsing function with resolution ≤1080P, which can monitor conductor galloping. Through image recognition and processing, it assists in diagnosing galloping information;
5. Stable and reliable battery charging management system, using MPPT (Maximum Power Point Tracking) technology to charge the storage battery, increasing solar charging efficiency by at least 20%;
6. Complies with the "General Technical Specifications for Transmission Line Condition Monitoring Devices" and supports access to power standard platforms;
7. Complies with the enterprise standard B interface requirements of "Power Grid Video Monitoring System and Interface" and supports access to the unified video platform of the internal network;
8. WeChat client is available, which regularly pushes galloping-related data and captured images to WeChat;
9. Equipped with a patrol inspection function to meet the monitoring needs of power departments. It records the patrol time and interval of inspectors in real time, preventing phenomena such as missed inspections and incorrect inspections;
10. The device has a built-in security encryption chip to realize encrypted transmission of data and ensure the security of data transmission.
