摘要
以往电网运行决策支持系统容易出现数据丢失的情况,导致电网决策效果较差,为此提出基于VRGIS平台的电网运行优化决策支持系统。设计VRGIS平台,使虚拟现实和GIS之间的数据共享,通过数据采集系统,将定制数据通过PCI总线传输到PC机。利用运行优化模型库管理系统,调度各种复杂查询情况。通过智能决策子系统,实现实时数据采集、处理、存储和发布。利用VRGIS分析方法预处理决策数据,将文件分块按照四叉树索引方式组合全部数据,消除操作系统的限制。实时绘制决策场景,消除硬件间的干扰,满足实时渲染的要求。由实验结果可知,该系统能够采集、检验、存储和发布50 bits数据,且与理想遍历结果一致,具有良好决策支持效果。
In the past,power network operation decision support system is prone to data loss,which leads to poor power network decision effect.Therefore,the power network operation optimization decision support system based on VRGIS platform is proposed.Design VRGIS platform,make the data sharing between virtual reality and GIS,through the data acquisition system,the custom data is transmitted to PC through PCI bus.The operation optimization model base management system is used to schedule various complex queries.Through the intelligent decision subsystem,real-time data acquisition,processing,storage and release are realized.VRGIS analysis method is used to preprocess the decision data,and the files are divided into blocks to combine all the data according to the quadtree index,so as to eliminate the restriction of the operating system.Real-time rendering of decision-making scene,eliminate the interference between hardware,to meet the requirements of real-time rendering.The experimental results show that the system can collect,verify,store and publish 50 bits data,which is consistent with the ideal traversal results,and has a good decision support effect.
