Fine Prediction and Early Warning System for Power Grid Icing and Galloping

Fine Prediction and Early Warning System for Power Grid Icing and Galloping

I. Overview

China has a vast territory with a wide range of climate zones and abundant climate types. In some areas of China, due to flat terrain without mountains or hills as barriers, and with mostly low shrubs as vegetation, strong wind weather often occurs. The transmission lines erected in these areas often swing significantly under the action of wind. This phenomenon has a special term in the power grid industry: transmission line conductor galloping. Galloping is a relatively frequent problem in the daily operation of power grids. Due to its complex formation reasons, serious consequences, and difficult observation, it is very unfavorable for intelligent security monitoring of power grids. In order to reduce the harm caused by galloping, Telcom has developed the Fine Prediction and Early Warning System for Power Grid Icing and Galloping.

III. Working Principle of Fine Prediction and Early Warning System for Power Grid Icing and Galloping

The built-in detection unit of the Fine Prediction and Early Warning System for Power Grid Icing and Galloping can collect real-time galloping data of the line, 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 status of multiple lines at the same time and respond to line abnormalities in a timely manner. The system uses wind-solar complementation for front-end power supply, making the overall installation of the equipment convenient. It adopts the power supply mode of wind-solar complementation plus battery, which can be directly installed on the conductor and started without frequent charging in the later stage.

IV. Postscript

The Fine Prediction and Early Warning System for Power Grid Icing and Galloping collects data such as the structure and parameters, direction, and meteorological conditions of the front-end monitoring line, and obtains the galloping status of the line through data processing and analysis in the background. The background can not only analyze the on-site situation, but also support the viewing of historical data. Operation and maintenance personnel can analyze and summarize a set of countermeasures suitable for preventing galloping hazards of local lines through the data changes of one week, one month or even one quarter, providing strong data support for the formulation of intelligent power grid monitoring solutions.

V. Product Advantages

The Fine Prediction and Early Warning System for Power Grid Icing and Galloping can collect meteorological data around the line and realize three-dimensional monitoring of the entire line through the platform's three-dimensional analysis algorithm; the optimized battery charging management system improves the efficiency of solar charging.
