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)...
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 ...
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...
matlab是一种用于算法开发、数据可视化、数据分析以与数值计算的高级技术计算语言和交互式环境。本文利用matlab的强大计算功能和信号数据处理功能,用FFT对连续信号和时域离散信号进展谱分析。 英文摘要: matlab is used in algorithm development, data visualization, data analysis and numerical calculation of high-level...

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...
在仿真文件的上面菜单栏,modeling》model settings》data input/export里面如果single simulation output被勾选上了,取消勾选再运行一遍就可以了,matlab版本2019b亲测有效,解决办法来源https://ww2.mathworks.cn/matlabcentral/answers/472454-fft-analysis-through-powergui-block-is-showing-empty-in-signal-options honor...
