DFIM Tutorial 1 - Implementation and Control of a DFIM in Matlab-Simulink

[@yassineboukili2813]

Good morning, Professor Gonzalo Abad, I would thank you for this educative series, it helped me a lot to start up with Induction machine control strategies.. 😇

[@sriharshini40]

This really helped me for my project called "compartive study of sensor less algorithms for doubly fed induction machine". Hope I can find related videos on it

[@gonzaloabadbiain5183]

Dear colleagues, I’m sorry but I cannot send you Simulink files. The video tutorial is just one more tool that can help to learn by oneself. If the objective is ‘to learn’, I think that I would not help sending you the files. Just the opposite. If we do a parallelism, if the objective is ‘to learn’ to ride a bicycle, one has to learn by himself/herself. Watching to other people how they ride can be useful (these video tutorials), but you have to do it by yourself. I am afraid thet there is no other path, if the objective is ‘to learn’. Thank you for your attention.

[@gonzaloabadbiain5183]

Simply by using the stator voltage equation, assuming the steady-state and neglecting the voltage droop at the stator resistance, we have (approx.): |Vs| = 2*pi*f*|Fs| ( sqrt(2/3) is to transform to phase-to-neutral and peak voltage/flux amplitudes )

[@shokha8816]

Nice to see this series for learning! I want to bring your notice that the oscillations in torques are 50Hz i.e grid frequency and they are not damp even if we increase Inertia. Secondly, the flux damping during grid fault is the big issue in DFIG as it needs few seconds to get completely damp depending on the Stator time constant (Ls/Rs). Is there a way to damp this oscillation and reactive power loop which you haven't implemented in this video can be made and be stable during Grid faults. Also can you please recommend any book for DC link voltage controller tuning and for the notch or low pass filter to remove 100Hz oscialltion during negative sequence decomposition?

Thank you for the wonderful video sir. On page 147 of the book you referenced "DOUBLY FED INDUCTION MACHINE" by R. Abari et al.,the output of the integrator of PLL is the angle of the grid voltage but in page 281 of the other book "POWER ELECTRONICS FOR RENEWABLE ENERGY SYSTEMS, TRANSPORTATION AND INDUSTRIAL APPLICATIONS" 90 degree was subtracted from the output of PLL to get the same grid voltage angle. Please can you explain the reason for this? Does it have anything to do with using stator voltage oriented control or stator flux oriented control?

for stator flux oriented control you have to substract 90 degree to stator voltage angle which we get from PLL

Thanks very much for the step-by-step demonstration. It helped a lot. The parameters worked for R2022b, though I think the motor block was a bit different, mainly, the rotor/stator voltage ratio parameter was introduced. If I use the default value 1, I got almost the same results as those in the tutorial. So I am a bit confused about the parameter turn's ratio, u, in the tutorial and how it is implemented in the simulation model. But as someone just starting to study the motors, building a simulation model by myself is definitely more interesting than just reading books.
