电力气象服务系统的设计与实现

气象条件对电力安全生产有着显著的影响，开展电力气象服务研究具有重要意义. 以用户需求为导向，结合气象数据特征，对于实况和临近预报，采用气象站对应的泰森多边形，对于短期预报和预警，采用区县行政区划，分别对输电线路和变电站进行切分，建立最近邻关系；同时，设计气象综合影响等级规范，提高服务的精细度. 利用GIS和数据库技术，建成一套能够提供监测实况、临近预报、短期预报、预警信号、历史查询和服务材料等信息的电力气象服务系统. 业务应用结果表明，系统运行稳定，能够提升气象服务水平，保障电力系统安全.

Design and Implementation of the Meteorological Service System for Electricity Industry

Meteorological conditions have a significant impact on the safe production of electric power, which is of great significance to carry out the research of the electricity meteorological service. Oriented by the user''s demand, combined with features of meteorological data, thiessen polygon corresponding weather station is used in live and nowcasting, and district and county administrative divisions is used in short-term forecasts and early warnings, to divide transmission lines and substations respectively, and then establish nearest neighbor relations. At the same time, meteorological comprehensive influence grade standard is designed to improve the fineness of service. A system of electricity meteorological service is built by GIS and database technology, which includes information about live monitoring, nowcasting, short-term predicting, signal of warning, historical queries, service material and so on. The results of the business application show that the system is stable, and is able to enhance the level of meteorological services, ensure the safety of power system.
