Abstract

The research is to study and design an electric circuit to emulate low-frequency oscillation in power transmission lines. The simulated signal is analyzed by Prony analysis to identify frequency and damping ratio. MATLAB program and Dynamic System Identification Toolbox are used to simulate and identify the oscillation information. The results is analyzed found that the oscillation frequency and damping ratio corresponding with designed values. Furthermore, a designed electric circuit will be used to implement low-frequency oscillation signal, which known frequency and damping ratio. These oscillation data will be used to verify correctness of the real-time algorithm to monitoring frequency and damping of power transmission lines in real-time event.
