Abstract

Abstract: Transmission line operation status is closely related to its meteorological environment. In order to improve ability to manage and control natural disaster risk of transmission lines, a real-time evaluation and early warning system for electrical reliability of transmission lines is developed based on meteorological parameters. According to traditional icing growth, dynamic accumulation, thunderstorm forecast and wind declination calculation models, with customized weather monitoring, numerical forecasting and other meteorological parameters from meteorological department, a risk evaluation and early warning system for icing flashover, pollution flashover, lightning and windage yaw flashover of transmission line is developed by adopting WorldWind 3D Geographic Information Framework and Web Service interface service technology. The system has been applied in some experiment lines. The evaluation and warning level output is basically consistent with actual operation. It is of great significance to grasp operating environment of transmission lines and take emergency measures before disaster emerging.

Key words: electrical reliability, evaluation and warning, meteorological parameter, 3D visualization
