Using labels with simpower simulink library

I was simulating a winding generator using the simpower library from Matlab's simulink and the schematic turn to be quite big. That when I discovered that labels (blocks "Goto" and "From" in simulink) don't connect to simpower wires. What are the…

reversing the "Measured voltage" in Simulink

Within Simulink, we can use the "Measure voltage" to get a numerical representation (Simulink Signal) of the voltage and use it for mathematical operations. Does there exist a way to take a numerical representation (Simulink Signal) and convert it…

One Cycle Fourier Window optimization. My code is inefficient

Good day EDIT: What I want: From any current/voltage waveform on a Power System(PS) I want the filtered 50Hz (fundamental) RMS values magnitudes (and effectively their angles). The current as measured contains all harmonics from 100Hz to 1250Hz…
