理解电力系统的动态需要以有意义的方式呈现信息。采用可视化的方法，给出了大型互联电力系统的大尺度模态分析结果，揭示了系统的底层振荡。可视化工具用于捕获多个总线信号之间的模态估计质量，识别系统中存在的不同模态相互作用，并可视化模态潮流以跟踪电网振荡源。利用广域可视化技术，在一个综合的大型互联电网中揭示系统动态状态的关键信息，否则，这些信息将无法从时变信号的图形图中捕获。
Understanding the dynamics of a power system requires that information be presented in a meaningful way. Large-scale modal results are presented for a large interconnected power system using visualization methods to reveal the underlying oscillations in the system. Visualization tools are used to capture the quality of mode estimation among several bus signals, identify different modal interactions existing in the system and visualize modal power flows for tracking sources of grid oscillations. The use of wide-area visualization in a synthetic large interconnected power grid is used to uncover critical information about the dynamic state of the system, which would have otherwise, not been captured from a graphical plot of the time-varying signals.
