基于图像处理的配电网差异性网格划分方法研究

Mesh Generation Method for Distribution Network Considering Differences Based on Image Pro-cessing

配电网规划所包含的元素越来越多,考虑差异化与精细化的网格化规划方法逐渐替代传统的规划方法。主要阐述了差异性网格化规划的含义,介绍了考虑网格划分的差异性规划的一般方法,提出了一种基于图像处理的网格划分方法,即基于负荷密度差异通过染色、合并的方法确定网格,并且提出了评估网格划分合理性的一致性指标。最后以某地开发区为算例,根据该方法给出最优网格划分并提出了相应的网架规划方案。

Distribution network planning contains more and more elements,and mesh planning method con-sidering differences and refinement gradually replaces the traditional planning methods.This paper focuses on the meaning of the mesh planning considering differences,introduces the general method of differential planning considering meshing,and proposes a meshing method based on image processing,generating the grid by dyeing and merging based on load density.Meanwhile a consistency index to evaluate the rationality of the meshing is proposed.Finally,taking a certain development zone as an example,the optimal mesh planning is given with this method and the corresponding grid planning scheme is proposed.
