基于气象参数的输电线路电气可靠性实时评估与预警系统设计与研发
|
摘要
输电线路的运行状态与所处的气象环境密切相关,为进一步提升输电线路自然灾害风险的在线管控能力,研发了一套基于气象参数的输电线路电气可靠性实时评估与预警系统。依据传统的输电线路覆冰增长、动态积污、雷暴预测以及风偏角计算模型,从气象部门引入定制化的实况监测、数值预报等气象参数,采用World Wind三维地理信息框架和Web Service接口服务技术,实现输电线路冰闪、污闪、雷击以及风偏闪络风险的评估与预警。该系统已针对部分线路线开展了试点应用,输出的评估与预警结果与实际运行情况基本吻合,对于实时掌握线路运行环境以及在灾害来临前采取紧急应对措施具有十分重要的意义。
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 World Wind3 D 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.
