摘　　要：介绍了基于广域量测系统(PMU平台)的电力系统低频振荡在线监测功能系统的设计及实现方法。低频振荡的在线分析主要采用多信号Prony算法分析,应用多输入Prony算法进行的在线特征模式分析计算功能,通过分析计算得出振荡的频率、系统的阻尼、特征值的实部和虚部,以及每个子站振荡幅值和相位,提供了PMU子站监测,在线Prony分析结果查看、频率振荡图查看以及实时数据查看等功能。The paper introduced the design and realization method for low-frequency osiUation based on PMU. The on-line analysis for low-fre-quency oscillation was mainly based on nmlti-signal Prony algorithm and utilizes the multi-input Prony algrithm to conduct the analysis and calculation function for on-line eigenvalue mode. The analytical calculation showed the frequency of oscillation, the damping of system, the real part and imaginary part of eigenvalues and the amplitude and phase of every substation, the result provides the function of PMU substation monitoring, viewing of on-line Prony analysis results, viewing of figures for frequency oscillation and viewing of real-time.
