摘　　要：针对传统技术在实际应用中绘制的可视化图像分辨率较低,难以展示清晰的智能变电站继电保护二次回路图像的问题,提出智能变电站继电保护二次回路可视化技术。首先使用SCD模型提取二次回路状态信息、物理信息等,并保存在网络访问中;然后利用可视化工具对二次回路信息进行分解和导入,为二次回路可视化展示提供数据;最后在可视化工具中通过映射二次回路之间的逻辑关系构建线路连接关系图,实现二次回路可视化展示。经实验证明,由该技术绘制的二次回路关系图像分辨率高于传统技术,具有良好的可行性和有效性。In view of the low resolution of the visual image drawn by the traditional technology in the practical application,it is difficult to display the clear image of the relay protection secondary circuit of the intelligent substation,the visualization technology of relay protection secondary circuit in intelligent substation is proposed.Firstly,the SCD model is used to extract the secondary circuit state information and physical information,which are saved in the network access.Then,the secondary circuit information is decomposed and imported by visualization tools to provide data for the visual display of the secondary circuit.Finally,in the visualization tool,by mapping the logical relationship between secondary circuits,the line connection diagram is constructed to realize the visual display of secondary circuits.Experiments show that the resolution of the secondary loop relationship image drawn by this design technology is higher than that of the traditional technology,and has good feasibility and effectiveness.
