基于CAD图样特征识别的变电站二次回路数字化建模研究与实践

Research and practice on digital modeling of substation secondary circuit based on CAD drawing feature recognition

现有变电站二次回路相关的信息主要以图形和文字的形式承载在CAD图样内,无法有效地实现数据信息的承载及应用,因此需要对CAD图样信息进行数字化建模。提出基于CAD图样特征识别的变电站二次回路数字化建模方法,利用CAD图样特征识别方法提取CAD图样内包含的变电站二次回路信息,基于变电站二次系统数字化模型框架实现变电站二次回路数字化建模,并将数字化模型用于二次全回路展示和辅助安措等高级工程应用。通过实际工程验证了所提方法的有效性。

The existing information related to the secondary circuit of the substation is mainly carried in the CAD drawings in the form of graphics and text, which can not effectively carry and apply the data information, so it is necessary to carry out digital modeling of the CAD drawing information. A digital modeling method of substation secondary circuit based on CAD drawing feature recognition is proposed. The information of substation secondary circuit contained in CAD drawings is extracted using CAD drawing feature recognition method. The digital modeling of substation secondary circuit is realized based on the digital model framework of substation secondary system, and the digital model is used for advanced engineering applications such as secondary full circuit display and auxiliary safety measures. The effectiveness of the proposed method is verified by practical engineering.
