电网运行状态可视化综述

电网运行状态包括电网在发电、输电、配电、用电这一完整过程中各个阶段的状态.面向电网运行状态分析的可视化方法,通过将专家经验融入数据分析过程,能有效地解决传统自动化方法的弊端,已被广泛应用于电网运行状态分析.文中介绍了电网数据可视化常用的3类数据,即图数据、时空图数据和多维数据,以及这些数据面向的4种可视化任务,即检测与辨认、相关性分析、态势感知预测.文中从数据和任务2个角度,回顾、总结了已有的可视化方法在解决电网实际应用问题中所起的作用,并分析了节点链接图、平行坐标图等多种可视化方法在不同电网运行状态分析任务中的利弊.研究分析表明,电网运行状态可视化仍面临着难以处理海量数据、实时流数据,并且缺乏完整、全面分析工具等诸多问题.

A Survey of Power Grid Operation State Visualization

Power grid operation state refers to the complete process of power generation, transmission, distribution and consumption. Visualization approaches used to analyze power gird operation state perform better than traditional methods by combining human knowledge into the data analysis process and therefore, are widely used for power grid operation state analysis. In this paper, we introduce the three most commonly used data types in power grid data visualization and the four visualization tasks. We survey and summarize the existing visualization works that are used to solve power grid problems. The advantages and disadvantages of these methods are explained from two perspectives: data and task. However, there still exist multiple challenges in this research domain, such as dealing with large-scale data and stream data as well as the lack of comprehensive analysis tools.
