Discrete Phasor domain in Simscape
显示 更早的评论
Dear community,
Is it possible to create an electrical model using Simscape blocks (blue ones) and solve it in Discrete Phasor domain, i.e. RMS quantities (as it can be done using Specialized Power Systems)?
If not, is there any other alternative?
Thank you very much in advance.
Best regards,
Víctor Sánchez Suárez

If you want to solve Simscape equations in phasor, try selecting "Frequency-and-time" as the Equation formulation on the Solver Configuration block.

Hi David,
Thank you very much for your quick answer. I have already tried that but I do not get phasors:

If you look in the simlog (using sscexplore), you will see instantaneous, offset, amplitude and phase.

Yes, there are periodic operator blocks that you can use to extract those signals. Actually, those blocks work in Time or in Frequency-and-time.
Open fl_lib, and then Physical Signals and finally Periodic Operators. This should give you what you're after. As I say, you can use either Equation Formulation with these blocks... Frequency-and-time may run faster for large models with a variable-step solver since the solver should be able to take larger steps.

Hi, thnkas, that helped me a lot.
Now, I am using the PS Harmonic Estimator (Amplitude, Phase) block, but I am getting a weird response. Calculated amplitude (blue curve) does not match the peak value of the sinusoidal waveform it is calculated from (yellow curve) when it increases in t=1s.
Why does this happen?

If you can share a model, I can take a look.
