Line Online Monitoring Device - Function: Sharing the Principle of Galloping Monitoring System

Line Online Monitoring Device - Function: Galloping Monitoring System

I. Overview

In nature, wind is a common weather phenomenon, and different wind forces have various impacts on us, such as wind power generation. However, for power transmission departments, excessive wind can sometimes affect the normal operation of transmission lines. When lines swing with strong wind, excessive swing amplitude can easily cause line tripping, and also aggravate the wear degree of line connection fittings. Power grid operation and maintenance personnel have no good solutions to this problem. The emergence of Telcom Line Online Monitoring Device - Function: Galloping Monitoring System provides power grid operation and maintenance personnel with data support when facing transmission line galloping disasters, facilitating the intelligent management of lines in the later stage.

II. Technical Parameters

1. Power supply system: Wind-solar complementation plus battery

2. Communication requirements: Supports wireless network communication (supports 4G and backward compatibility), adapts to China Telecom, China Unicom and China Mobile, and operators can be selected according to on-site conditions

3. Working voltage: DC12V

4. Working temperature: -40~70℃

5. Single sampling points: More than 400 points

6. Environmental weather station parameters: High-precision ultrasonic sensor, which comprehensively measures parameters such as ambient temperature, humidity, wind direction, wind speed, air pressure, rainfall, etc.

III. Line Online Monitoring Device - Function: Galloping Monitoring System Working Principle

The built-in detection unit of Line Online Monitoring Device - Function: Galloping Monitoring System can collect real-time galloping data of lines, and send the data to the back-end management platform in real time through the wireless communication module. Operation and maintenance personnel can remotely monitor the galloping conditions of multiple lines at the same time, and respond to line abnormal conditions in a timely manner. It adopts wind-solar complementation for front-end power supply, and the whole equipment is easy to install. With the power supply mode of wind-solar complementation plus battery, it can be directly installed on the conductor and started, without frequent charging in the later stage.

IV. Application Cases

There are two sections in the lines under the jurisdiction of a municipal power department in Shandong Province that often have the problem of excessive line galloping amplitude. The reason is that the conductors in this area are prone to uneven icing, and the area around the conductors is open with no shelter, so it is often windy. This leads to rapid wear of line clamps and fittings, and even power outage accidents. After the installation of Line Online Monitoring Device - Function: Galloping Monitoring System, operation and maintenance personnel can view the on-site conductor galloping data anytime and anywhere, avoiding the serious consequences caused by being unable to respond in time when the conductor galloping amplitude is too large.

V. Postscript

The problem of transmission line galloping has always been difficult to monitor, so power grid departments have not had good means to deal with it. In addition, with the frequent occurrence of extreme weather in recent years, the originally regular wind season has become unpredictable. Operation and maintenance personnel cannot obtain real-time on-site galloping data, so they cannot respond to the disasters caused by galloping in a timely manner. Telcom Line Online Monitoring Device - Function: Galloping Monitoring System can monitor several characteristic quantities of lines during galloping disasters in real time, and send them wirelessly to the back end. The back-end software compares the set early warning values to decide whether to send an alarm to operation and maintenance personnel, enabling them to take the initiative when facing galloping problems.
