摘　　要：电力应急指挥系统是一个基于B／S结构的综合可视化平台，实现电网应急管理从经验型向分析型转变。系统采用GIS技术手段实现可视化功能，为管理者提供其区域范围内的数据展示，提供快速，准确的决策支持。该文比较了当前主流的WebGIS平台以及实现技术，结合南方电网具体项目的需求，给出了一种改进的WebGIS在该应用系统中部分实现方法以及主要算法。利用顸生成瓦片技术提高地图的浏览、查询、地理分析等出图效率，解决了传统WebGIS速度和效率瓶颈。The Emergency Command System for Electric Power is a visualization platform based on B / S structure to achieve Power Grid emergency management from experience to analysis type. The system uses GIS technology to achieve visualization capabilities, and provides the data display of determined areas, and accurate decision support. This paper makes a description of the popular development technology. With the project of Emergency Command System for Southern Power Grid, it gives the one kind of improvement of WebGIS and algo- rithms in this application. Using pre-generated map tiles technology to enhance browsing, query, geographical analysis, the efficiency of the plan to solve the bottleneck of traditional WebGIS speed and efficiency.
