How analyze PMU data in the form of sinusoidal waveform?

Dear experts.
I need your help with PMU dataset analysis. I am wondering how to plot sinusoidal waveform if we have PMU data then apply time-frequency analysis method such as Fourier Transform, Wavelet, etc.
I appreciate any tips, guide and help.

hello
I am not sure what your data represents, but FYI, this is a code to do spectral analysis (averaged fft and spectrogram)

hello
I see there is a lot of publications about PMU on the internet
maybe you should take contact with some of the authors , they may have the raw data you need
all the best

Many thanks Mathieu for your kind help. I really appreciate it.
I will try to my best. It is my thesis assignment, however the time is very constrained.
