连续模态参数估计技术的使用证明了验证动态系统模型的目的。通过使用包含小信号振荡的模拟信号代替真实的电力系统测量，显示了估计与基本系统参数的一致性。值得注意的是，测量位置的选择是很重要的模式可观测性的原因。使用模态振型估计也证明，估计的模态振型与模型的期望是一致的。结果表明，模态参数估计器对有实际意义的模态有较好的估计效果，适用于动态系统模型的验证。
The use of a continuous modal parameter estimation technique is demonstrated for the purpose of verifying a dynamic system model. By using simulated signals containing small-signal oscillations in place of real power system measurements, the consistency of the estimations with underlying system parameters are shown. It is noted that the choice of measurement location is important for reasons of mode observability. The use of mode shape estimation is also demonstrated, and the estimated mode shape is shown to be consistent with the model expectation. It is concluded that the modal parameter estimator performs well for modes of practical significance, and is suitable for verifying dynamic system models.
