基于Web GIS的省地县一体化小水电管理系统设计与实施
|
摘要
针对小水电点多面广、无法实时监视、统一分析困难等问题,设计并开发了基于Web GIS的省地县一体化小水电管理系统。该系统以Applet作为表示层,采用Java2D技术以矢量图形式对小水电GIS信息进行分级分层展示,实现小水电信息的全面监视;结合JNLP技术实现地理信息缓存,加快数据加载速度,增加用户体验和可操作性;对各分区小水电运行信息进行实时统计分析,并提供水位、出力等告警信息,为各级调度人员提供辅助决策支持。在云南电网实践运行表明,该系统具备有效性和实用性,可以满足大规模小水电管理的实际应用需求。
In view of wider distribution,hard to real-time monitoring and difficult to unified analysis of small hydropower,a Web GIS based small hydropower management system is developed.The system uses Applet and Java 2D to show vector GIS information hierarchically and realizes the overall monitoring of small hydropower information.By combining with JNLP,the system can cache the GIS information and related data to accelerate the response and the user experiences.The system can also analyze operation information and show warning information to provide decision support for each department The application of system in the management of small hydropower in Yunnan power grid has verified its effectiveness and practicality,and shows it can satisfy the requirements of large-scale integrated management of small hydropower.
