摘要

本课题的目的是研究和设计一种模拟输电线路低频振荡的电路。利用proony分析法对仿真信号进行分析，确定频率和阻尼比。利用MATLAB程序和动态系统识别工具箱对振荡信息进行仿真和识别。分析结果表明，振动频率和阻尼比符合设计值。此外，设计的电路将用于实现已知频率和阻尼比的低频振荡信号。这些振荡数据将用于验证实时算法在实时事件中监测输电线路频率和阻尼的正确性。

A design and construct an electric circuit to emulate power system oscillation in tie-line systems

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.
