Fine prediction and early warning system for icing and galloping of power grids

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

I. Overview

China has a vast territory, spanning a wide range of climate zones with diverse types. In some areas of China, due to flat terrain without barriers from mountains or hills, and with vegetation mostly consisting of low shrubs, strong winds often occur. The transmission lines erected in these areas frequently experience large-scale swinging driven by wind. This phenomenon has a specific 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 causes, severe consequences, and difficulty in observation, it poses significant challenges to intelligent security monitoring of power grids. To mitigate the hazards caused by galloping, Telincon has developed the Fine Prediction and Early Warning System for Power Grid Icing and Galloping.

III. Working Principle of the 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 lines, and transmit the data to the backend management platform in real time via a wireless communication module. Operation and maintenance personnel can remotely monitor the galloping status of multiple lines simultaneously and respond promptly to line abnormalities. The system uses wind-solar complementation for front-end power supply, making the overall equipment installation convenient. With the power supply method of wind-solar complementation plus battery, it can be directly installed on the conductor and started, without the need for frequent charging in the later stage.

IV. Conclusion

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 monitored lines at the front end. Through data processing and analysis at the backend, it obtains the galloping status of the lines. The backend not only can analyze on-site conditions but also supports historical data viewing. Operation and maintenance personnel can analyze and summarize a set of countermeasures suitable for local lines to prevent galloping hazards through data changes over a week, a month, or even a 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 lines and achieve 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.
