对于大型电力系统来说，一个持续的挑战是以一种最大化人类用户态势感知的方式显示广域数据。本文描述了一种新的可视化技术，该技术绘制彩色瓷砖马赛克来表示电网对象的多个数据字段，排列以保持地理环境。创建这些图表的关键问题是将瓷砖包装到显示空间中，最小化总位移，同时禁止重叠。本文阐述了这一问题，并提出了一种水平填充算法，该算法能够在交互时间尺度上产生一个可行的、高质量的解。举例说明了使用马赛克来监测广域发电机状态和调度，总线电压，以及线路和变压器限制。马赛克可以通过多种方式进行定制，以显示系统状态的不同方面，为人类用户同时提供广域总结、区域趋势和突出的异常值的感觉。
For large power systems, a continual challenge is to display wide-area data in a way that maximizes human users' situational awareness. This paper describes a new visualization technique that draws a mosaic of colored tiles to represent multiple data fields for electric grid objects, arranged to preserve geographic context. The key problem in creating these diagrams is packing the tiles onto the display space, minimizing the total displacement while forbidding overlaps. This paper formulates that problem and presents a horizontal-packing algorithm which is able to produce a feasible, quality solution at an interactive time scale. Illustrative examples are shown for using mosaics to monitor wide-area generator status and dispatch, bus voltages, and line and transformer limits. Mosaics can be customized in numerous ways to show different aspects of the system state, providing for human users a simultaneous sense of the wide-area summary, regional trends, and prominent outliers.
