I am ruing the same model: a three-phase source and diode rectifier and measuring the same signals. It seems that the Simscape model is slower than the Specialised Technology when running in Accelerator mode.
The test code is
Tstop = 2;
Power.Ts = 1e-6;
tic
sim('Rectifier_Simscape');
toc
tic
sim('Rectifier_Specialised');
toc
Files are in the attachment (R2018a).
Results are
Initial run (empty workspace):
- Elapsed time is 8.078532 seconds.
- Elapsed time is 5.754597 seconds.
Second run:
- Elapsed time is 5.905777 seconds.
- Elapsed time is 4.282237 seconds.
3rd run:
- Elapsed time is 5.629353 seconds.
- Elapsed time is 4.345153 seconds.
Is is possible to speed-up the Simscape model?
I plan to expand the model and add dc/dc and dc/ac converters, filters, switches, etc and now even with the passive elements, the Simscape is >30% slower
