针对城市配电网变电站配电变压器选址规划能力不足的问题,提出了城市配电网变电站配电变压器选址辅助决策研究。引入虚拟现实的视景仿真技术,构建配电变压器选址的视觉规划模型。运用空间区域像素特征分解方法,在选址过程中对视觉信息特征进行采样。采用增强现实技术,对选址视景信息融合处理,根据信息融合结果,实现选址空间区域规划和网格分块匹配,从而优化选址,为快速规划审批修改提供了快捷便利性。研究表明:该方法对城市配电网变电站配电变压器选址的视觉重构能力较好,选址辅助决策的虚拟现实优化仿真结果可靠性达到0.997,匹配度达到了0.974,辅助提高了城市配电网变电站规划选址能力。

Aiming at the problems of insufficient planning capacity and high operation loss of distribution transformer in urban distribution network substation,a location method of distribution transformer in urban distribution network substation is proposed.Firstly,the visual simulation technology of virtual reality is introduced to process the visual reconstruction in the process of distribution transformer location,and the visual planning model of distribution transformer location is constructed.Secondly,the spatial region pixel feature decomposition method is used to sample the visual information features in the process of location selection.Finally,the augmented reality technology is used to process the location visual information.According to the results of information fusion,the spatial planning and grid block matching of site selection are realized,and the location optimization is realized,which provides convenience for rapid planning approval and modification.The results show that the visual reconstruction ability of the proposed method is good, the parameter configuration accuracy is high, the time and space of uploading and downloading are saved, and the planning and location ability of the urban distribution network substation is improved.
