在电力系统的实时监测和分析中，系统受到扰动时出现的动态现象的表征是很重要的。本文讨论了使用希尔伯特谱分析可视化和表征非线性振荡同步广域测量。该方法具有应用于实时，广域监测和分析的潜力。作为一个说明性的例子，同步相量测量的一个真实的事件在北方墨西哥被用来研究潜在的有用性的非线性时间序列分析技术，以表征非线性，非平稳振荡的时间演变，并确定系统扰动的性质和传播。并与Prony分析方法进行了比较
Characterization of the dynamic phenomena that arise when the system is subjected to a perturbation is important in real-time power system monitoring and analysis. This paper discusses the use of Hilbert spectral analysis to visualize and characterize nonlinear oscillations from synchronized wide-area measurements. The method has the potential to be applied for real-time, wide-area monitoring and analysis. As an illustrative example, synchronized phasor measurements of a real event in northern Mexico are used to examine the potential usefulness of nonlinear time series analysis techniques to characterize the time evolution of nonlinear, nonstationary oscillations and to determine the nature and propagation of the system disturbance. The proposed approach is also compared with Prony analysis
