1.在仿真里面拖入powergui模块2.设置所要分析的波形，保存入workspace，格式:Structure with time3.进行仿真，完毕后，进入powergui的FFT Analysis4.在Structure中选择信号名称等等。下面是开始计算的时间，特别是有的波形开始比较乱，建议你从比较稳定的一段开始计算，接着是计算的周期，数目越大，时间越长...
The Application of FFT Analysis on the Feeder Current Based on the Smooth Function in MATLABFast Fourier transform(FFT) is an important tool for harmonic analysis in power systems and a method of FFT analysis of the signal is very important for power systems. For finding and forming a basic ...
Thepersistence spectrumof a signal is a time-frequency view that shows the percentage of the time that a given frequency is present in a signal. The persistence spectrum is a histogram in power-frequency space. The longer a particular frequency persists in a signal as the signal evolves, the...
powergui模块配置界面中点击“Tools”标签,可以进入工具选择界面,点击“FFT Analysis”: 选择需要处理的信号名 需要处理的信号周期数量 信号的基波频率,也就是理想波形的频率。需要根据具体信号单独设置,本模块中设置为400Hz 计算总谐波失真(THD)的频率范围,可选择与最大频率相同,也可选择采样频率的一半(奈奎斯特频率)...
Hi, In simscape electrical addon, I use powergui, I am trying to use FFT Analysis tool but I got MATLAB R2021a has stopped working error. Whenever I use other tools as Machine Initialization,Impedance Measurement, Use Linear System Analyzer, Hysteresis Design.. etc. there is no error. But...

To better assess the peak frequencies, you can increase the length of the analysis window by padding the original signal with zeros. This method automatically interpolates the Fourier transform of the signal with a more precise frequency resolution. Identify a new input length that is the next po...
