摘　　要：当前基于潮流计算的电网静态安全分析存在智能化程度不高、图-表-数信息割裂、耗时耗力和低效等问题。针对其中数字化与可视化环节,提出一种面向智能化电网安全分析的网架信息数字化与潮流结果可视化方法。详细说明了电网潮流数字化与可视化模块的框架,并着重介绍了基于图像识别技术的网架信息获取算法。以某省份电网为例说明了实现过程和实施效果。模块的核心内容高准确率地提取了数字化的网架信息,改变了现有的网架拓扑输入方式,完成了智能化电网静态安全分析自动化设计的重要一环,为电力系统的数字化智能化发展提供了支撑。At present,the static security analysis of power grid based on power flow calculation has some problems,such as low intelligence,separation of graphs,tables and numbers information,time-consuming,labor-consuming and low efficiency.Aiming at the digitization and visualization links,a method of grid information digitization and power flow result visualization for intelligent power grid security analysis was proposed.The framework of power flow digitization and visualization module was described in detail,and the grid information acquisition algorithm based on image recognition technology was emphatically introduced.Taking a provincial power grid as an example,the implementation process and implementation effect were illustrated.The core content of the module extracts the digital grid information with high accuracy,changes the existing grid topology input mode,and completes an important part of the automatic design of static security analysis of intelligent power grid,which provides support for the digital and intelligent development of power system.
