采用当前方法对混合气体绝缘开关设备(HGIS)配电装置紧凑型布置进行优化设计时,由于没有构建配电装置现场三维模型,造成优化效率低、合理性差和网络损耗大等问题,为此提出基于三维建模的HGIS配电装置紧凑型布置优化方法。在立体视觉原理的基础上采用四目立体系统获取三维坐标,构建HGIS配电装置现场三维模型。在三维建模的基础上将配电网网络损耗最小、系统电压稳定性最高、电压偏移最小作为优化目标,构建HGIS配电装置紧凑型布置优化模型,采用萤火虫算法对布置优化模型进行求解,实现HGIS配电装置紧凑型布置的优化。实验结果表明,所提方法的优化效率高、合理性好、网络损耗小,实际应用效果较好。

When the current method is used to optimize the compact layout of hybrid gas insulated switchgear(HGIS)distribution equipment,there are some problems such as low optimization efficiency,poor rationality and large network loss due to the lack of 3D model of power distribution device.Therefore,an optimization method of HGIS distribution device compact layout based on 3D modeling was proposed.Based on the principle of stereo vision,the 3D model of HGIS power distribution device was constructed by using four eye stereo system to obtain three-dimensional coordinates.On the basis of 3D modeling,the minimum network loss,the highest system voltage stability and the minimum voltage offset were taken as the optimization objectives,and the compact layout optimization model of HGIS distribution equipment was constructed.The firefly algorithm was used to solve the optimization model,so as to realize the optimization of HGIS distribution device compact layout.The experimental results show that the optimization efficiency of the proposed method is high,the rationality is good,the network loss is small,and the practical application effect is good.
