【摘要】：随着电网规模不断扩大,电网结构的复杂度大大提高,保证电网安全、可靠的运行的任务十分艰巨。面对海量的电网数据信息,传统的图表显示不利于对数据的内在规律进行分析,数据的高效管理和分析无疑是一个重要课题。WebGIS具有强大的地理空间分析、空间检索以及可视化展示能力,通过各种先进的算法,能够将电网中呆板、枯燥的数据信息以直观的图形、图像方式进行展示,使用户可以快速地获取到关键信息,对电网的不同情况采取更加有效、快速的运行控制策略。本文以电力系统的实际应用需求为出发点,采用ArcGIS Server作为WebGIS基础开发平台,设计了基于B/S模式的三层系统架构,系统通过不规则三角网生成法、内插法、射线法等算法和等高线、动态饼图、点密度图等方式对电网节点数据、线路数据以及区域数据等进行可视化展示。并通过SVG及JavaScript等技术实现了一次接线图的图形交互操作、信息分层展示以及设备信息查看等功能,同时采用Ajax异步通信方式实现了实时数据的刷新展示。通过在WebGIS平台上对电网运行数据进行可视化展示,使电网运行人员能够直观的了解当前电网的运行状况,便于对电网进行监测、管理以及维护,进而有效地保证了电网安全、可靠的运行,大大的提高了工作效率,在电力实际应用中具有重要意义。
[Abstract]:With the continuous expansion of power network scale, the complexity of power network structure is greatly increased, and the task of ensuring the security and reliable operation of power grid is very arduous. In the face of massive power grid data information, the traditional chart display is not conducive to the analysis of the inherent laws of the data, the efficient management and analysis of data is undoubtedly an important subject. WebGIS has a strong geospatial analysis. Spatial retrieval and visualization display ability, through various advanced algorithms, can display the dull, boring data information in the grid with intuitive graphics and images, so that users can quickly obtain the key information. More effective and fast operation control strategy is adopted for different conditions of power grid. Based on the practical application requirements of power system, this paper uses ArcGIS Server as the basic development platform of WebGIS, and designs a three-tier system architecture based on B / S model. The system is generated by irregular triangulation and interpolation. The algorithms such as ray method, contour line, dynamic pie chart and point density map are used to visualize the node data, line data and area data. The functions of graph interactive operation, information layer display and device information viewing are realized by using SVG and JavaScript technology. Meanwhile, the real-time data refresh display is realized by Ajax asynchronous communication. Through the visual display of the grid operation data on the WebGIS platform, the operators can understand the current operation status of the grid intuitively, facilitate the monitoring, management and maintenance of the power network, and then effectively ensure the security of the power grid. Reliable operation, greatly improve the working efficiency, in the practical application of electric power has important significance.
