电力系统动力学分析有助于理解电力系统的运行。因此，设计和开发先进的可视化工具来解释频率、电压幅值和相角信息，使其能够以直观的方式呈现给操作员是非常重要的。在广泛分布的频率扰动记录仪（FDR）采集的测量数据的基础上，实现了FNET系统的可视化工具。本文讨论了FNET的几种可视化工具，包括实时可视化、动画事件回放、振荡模式分析可视化和二维系统传播效应可视化。这些工具将FDR测量值与其相应的地理信息相关联，并使用各种计算机技术和编程语言将组合矩阵转换为不同的图形格式。这些工具生成的图形通过允许操作员监控电力系统动态、执行事后分析和更有效地识别模态振荡来促进电力系统操作。
Analysis of power system dynamics helps to understand the operation of a power system. Therefore, it is significant to design and develop advanced visualization tools to interpret frequency, voltage magnitude, and phase angle information so that it can be presented to the operators in an intuitive manner. On the basis of the measurement data collected by widely-distributed frequency disturbance recorders (FDRs), visualization tools have been implemented for the FNET system. A number of FNET visualization tools are discussed in this paper, including real-time visualization, animated event replay, visualization of oscillation mode analysis and visualization of propagation effects in two dimensional systems. These tools correlate the FDR measurements with their corresponding geographical information, and transform the combined matrices into different graphic formats using various computer techniques and programming languages. The graphics generated by these tools facilitate power system operation by allowing an operator to monitor power system dynamics, perform post-event analysis and identify modal oscillations more efficiently.
