摘　　要：针对PSD-BPA的地理接线图绘制软件存在的缺陷和不足,提出了一种以Qt库为基础的电力系统地理接线图绘制软件设计方法。首先,按照软件的功能需求,以及各模块间相互独立、视图数据相互分离的设计思想将软件划分为3层结构:数据服务层、绘图操作层和辅助功能层。然后,以Qt图形视图框架为基础建立了软件的主体绘图框架,并详细阐述了数据库视图框架、潮流动画功能以及接线图输出技术的实现方法。In view of the disadvantages of the geography diagram drawing software of PSD-BPA,a design method of power system geography diagram drawing software based on Qt library is proposed.First of all,the software is designed to consist of a three-layer architecture（the data service layer,drawing operation layer and auxiliary function layer）in accordance with the functional demands on the software,as well as the design ideas that the modules are independent of each other and the view is separated from data.And then the main drawing framework is designed based on the graphics view framework of Qt.The implementation of the framework of the database view,the function of flow animation,and the wiring diagram output technology are presented.
