| 中文摘要 | 电压等高曲面图是一种能够直观反映全网电压状况的先进的可视化技术,目前主要存在计算和显示耗时长的问题,不能满足展示电力系统动态过程的要求。文中介绍了几种基于规则网格的空间插值算法,分析了空间插值算法的统一形式。从对图形的不同区域运用不同分辨率的思路出发,提出了一种基于网格合并的新方法,将规则网格中权重向量相近的格子合并为更大的格子组,以此来减少需要插值和绘制的格网数目。在不影响图像质量的前提下,电压等高曲面图的显示速度得到了大幅提高。; Voltage contour visualization can help system operators grasp the overall situation of the system voltage profile and quickly identify any voltage violations. However,the overhead of the interpolation computation and graphic rendering could be an obstacle to the practical application. This paper discusses several types of spatial interpolation algorithms and their unified form. Inspired by the idea that uses different resolutions in different locations on the screen,a new grid mergence method is proposed. Adjacent rectangles with similar weight vectors are merged into larger rectangles. The number of rectangles that need processing is greatly reduced. Without sacrificing the image quality,the display speed is significantly improved. |
