摘　　要：电网气象信息应用系统是充分利用气象信息资源为电网气象灾害预警预防和电网运行管理精细化提供辅助决策支持,进而有效实现电力设施防灾、减灾的一套应用性气象信息系统。本文探讨了使用气象台的格点数值预报数据、杆塔位置信息及线路设备台账信息,结合输电线路动态传输载流量与气象因素的相关关系,建立输电线路载流量预报模型。模型结合恶劣的环境边界条件、设计应用环境条件和格点气象数值预报环境条件下的导线载流量、电网地理信息系统,形成输电线路载流量预警机制,开发实用的输电线路容量预报预警功能模块,用于电网运行与调度。Grid Meteorology Information System is an application system which makes full use of weather information to provide decision support for meteorological disasters warning and meticulous management of Power Grid.In addition,the system will effectively achieved weather disasters prevention and mitigation of power system. Based on the relationship between the grid data of forecast weather elements and wire power load information,the paper established a power load forecasting model.The model combined the environmental boundary conditions,numerical weather prediction and geographic information to develop a transmission line capacity forecasting and early warning function module for Power Grid operation and dispatching.
