transmission line 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 statistical data to calculate and restore the galloping trajectory. 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, making the most of outdoor power in real time. The system remotely collects galloping, micro-meteorological and image data, then digitally compresses and encodes the data, and finally transmits the on-site data to the data monitoring center in the form of IP packets via 4G/3G/GPRS/CDMA wireless transmission modules. 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 analyzes and processes them in combination with conductor galloping data;
3. Intelligent galloping analysis: 3D parameters are established when the device is first installed through the platform's 3D analysis algorithm. Based on the MATLAB algorithm and comprehensive sensor and image data, a three-dimensional monitoring system is formed for the entire monitored line;
4. Real-time video browsing function with a resolution of ≤1080P, which can monitor the conductor galloping situation. 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 battery, increasing solar charging efficiency by at least 20%;
6. Supports the "General Technical Specifications for Transmission Line Condition Monitoring Devices" and accesses the power industry standard platform;
7. Supports the enterprise standard B interface requirements of "Power Grid Video Monitoring System and Interfaces" and accesses the unified video platform of the internal network;
8. Equipped with a WeChat client, which regularly pushes galloping-related data and captured images to WeChat;
9. Equipped with a patrol inspection function, meeting the monitoring needs of power departments. It records the patrol time and interval of inspection personnel in real time to prevent phenomena such as missed inspections and incorrect inspections;
10. Built-in security encryption chip, realizing encrypted transmission of data and ensuring data security.
