摘　　要：随着电网规模不断扩大,电网地理接线图越来越复杂,其绘制、维护愈发困难,已成为电力调度自动化运维工作的一大难点。本文介绍一种基于电网全景模型,综合厂站范围指定、经纬度定位、T型接线(简称T接线)同步生成、多图层展示等多项技术的电网地理接线图自动成图方法,适用于各种级别和复杂度的电网。该方法依托间隔容器模型,引入T接线同步生成技术,使成图完整性极大提升;根据电网设备电压等级不同,引入多图层技术,实现地理接线图不同电压等级设备的分图层展示,使成图效果显著加强;成图布局支持人工调整,且图模异动后不被自动复原,有效弥补了自动成图在局部处理时存在的不足。目前,该方法已在某地区电网的智能电网调度控制系统中实现首次应用。实践证明,该方法大幅降低了电网地理接线图在绘制及更新过程中的人力成本,具有广阔的推广前景。With the constantly expanding of the power grid,the geographical wiring diagram of the power grid is becoming increasingly complex.Its drawing and maintenance are very difficult,gradually becoming a major difficulty in the operation and maintenance of power dispatch automation.This article introduces an automatic mapping method for power grid geographic wiring diagrams based on a panoramic model of the power grid,which integrates multiple technologies such as specifying the scope of power plants and stations,latitude and longitude positioning,T-line synchronization generation,and multi layer display.It is suitable for various levels and complexities of power grids.This method reliesg on the interval container model and introduces T-line synchronous generation technology,greatly improving the completeness of the mapping.According to the different voltage levels of power grid equipment,the introduction of multi layer technology enables the display of equipment with different voltage levels in geographical wiring diagrams,significantly enhancing the mapping effect.The mapping layout supports manual adjustment and is not automatically updated after model changes,effectively compensating for the shortcomings of automatic mapping in local processing.This method has been applied for the first time in the dispatch control system of a smart grid in a certain region.Practice proves that this method significantly reduces the labor costs incurred in the process of drawing and updating the geographic wiring diagram of the power grid,and has broad prospects for promotion.
