摘要

电力系统脉冲响应的估计是电力系统性能评估的重要组成部分之一。脉冲响应数据可用于电力系统动力学建模和控制，以及基于稳定性分析的系统规划。本文给出了用连续小波变换估计电力系统冲击响应模态参数的初步结果。利用模拟的基准信号，讨论了小波模态估计在电力系统中的优点和局限性。

Estimating power system modal parameters using wavelets

Estimation of the impulse response of power systems is one of the important parts of power system performance assessment. Impulse response data can be used for modelling and control of power system dynamics, and system planning based on stability analysis. In this paper, the preliminary results of modal parameter estimation of impulse response of power system using continuous wavelet transform are presented. The advantage as well as limitation of wavelet based modal estimation when applied to a power system is discussed using simulated benchmark signals.
