Hi, thank you so much for a very useful video. I'm studying this topic and i want to learn more about the control strategy that you're using in this video. So can you give me some references about this, it would be very helpful for me. Thanks again
The video is very detailed and helped me a lot. I have one observation though. The RMS value of the line-to-line output voltage in this inverter is not 400-V. It is 282.84 V. The peak of line-to-line voltage is set to be 400-V. Please correct me if I am wrong.
Sir, I suggest you make one video that includes the practical implementation of inverter control design and external relays (like MCB, Precharge etc) to DSP Board (C2000)
Hi, Thanks for your awesome videos. 1- Could you please explain how should we design the PI controller's parameters? 2- Can you please provide a video on parallelizing two or more inverters in islanded mode (Grid forming and following)?
I redid your simulink simulation above and noticed that when I increase the coil inductance, the THD decreases, and when I decrease it, the THD increases. I thought it should be the other way around.
Thank you Sir for the video. Sir, how did you calculate the value of R in LCL filter? Sir, please post video for fault conditions occuring and how it can be rectified in this circuit.
R is the series resistance of the inductor and its value will always be in the order of milli ohms. So i put some random value. Fault conditions and other things i will try to make video. Thanks for your suggestion.
in real implementation of this circuit the abc-dqo direction conversion is not giving correct result. also the abc to dqo block is not taking 3-phase voltages generated by inverter.. pls help to solve this query
What you have gone through is called an islanding operation. The way the VSI works is totally different. VSI in such cases dictates the voltage and frequency, which are generated through droop control loops. Droop control is mandatory. You need to re-consider your video.
You can set the required voltage reference either as vd or vq. If you keep the reference in vd and keep vq zero, then voltage in the fiirst phase (that is VR) will align in phase with angle information(wt) that we are giving externally. If you keep vd zero and set the required reference in vq, then there will be 90 degree phase difference between voltage VR and angle (wt).
In my single phase inverter videos, i have explained these things. But i havnt explained it well for 3 phase inverter because of its complexity . Anyways i will try to make a separate video of explaining all these things

One of the best channel i have seen so far. How you have chosen the value of Kp and Ki? kindly make a video for this ? thanking you in advance.......
AMAZING!!! As it's said, knowledge is power, and you are sharing it. THANK YOU.

Best channel for PV simulations
I found it very precisely and well covered video tutorial. Appreciate your great effort. Expecting many more to watch!!!
Thank you. I am trying to make more such videos.
@@TechSimulator ❤️👌
Hi.sir, what you measure voltage Va is phase to phase ,right? how to change meaure phase to ground, it the modeling work as same ?
I redid your simulink simulation above and noticed that when I increase the coil inductance, the THD decreases, and when I decrease it, the THD increases. I thought it should be the other way around.
Your video tutorials are great.Could you explain why use 800/2 for gain module？Thank you.
Thank for your great efforts. Hope you really taken Lf=500e-6
Your video tutorials are great. Can you make video on hybrid microgrid, on ac side we have wind dfig and on dc side we have PV with loads?
Very informative video and I learned some good things here. Just a question, based on what did you choose the kp & ki values for both loops.
awsome explanation.
Could you please explain how to use 3 phase universal IGBT block at once instead of used 6 IGBT
Wish that you can continue efforts
👍👍

@@TechSimulator Thank you very much for your immediate response.My sincere thanks and wishes to your knowledge sharing tendency.
How to select the values of Kp and Ki of the PI controller? please do share information regarding the PI controller and gain selection.
Great work, can you share the system in Matlab please if it can be?
Could you explain the concept of getting Idref from voltage controller since
the input is voltage?
Kindly share the paper which you used to select the values of L,C, kp and ki.
Thanks indeed for your contribution. Can you make simulation for parallel inverter connected to grid ( microgrid) , please?
Yes. Sure. I have few other videos pending. After that i will upload.
@@TechSimulator thanks indeed Mr.
Hi sir, Thanks for your videos. Could you please provide a link to the reference paper for the control scheme in this video?
How did you choose Kp and Ki values?? I need Vd ref as 415*sqrt(2) but the current values for Kp and Ki aren't working
Can you please
upload one video regarding Droop control of AC microgrid.
in real implementation of this circuit the abc-dqo direction conversion is not giving correct result.
also the abc to dqo block is not taking 3-phase voltages generated by inverter.. pls help to solve this query
if I change the load to an induction motor, is it possible? and what parameters need to be changed?
motor take huge starting current and if the inverter can support that, then no issues
Good job sir but when l change load from R to RL the peak voltage above 1500V can u expalin why?
make sure that the load doesnt exceeds the rated value
Here we are getting a phase shift in current and so there is reactivate power loss even while using purely resistive load... How can we avoid that?
Great job
Thanks brother
how can u use the PWM1 in block From if the names in the GOTO blocks are not PWM?
never mind, you added goto logics later....
If i want to track both Vd n Vq then?
if i connect pv module instead of dc supply
can u tell me the strin data
simulation of three level grid connected inverter based distributed generator. Please help me
How reactive power coming in this becoz Vq is 0
Sir, can you please upload videos for point to point connection of converters.
What you mean by point to pint connection?
@@TechSimulator HVDC Transmission where converter plays both as an inverter and rectifier .
Ya. I got. Will try to post some videos.
@@TechSimulator Thank you Sir

Why droop is required, since i dont have a second inverter connected in parallel
How to do it grid connected ?
already there in my channel
Thks sir
Good one Sir can you provide information on FOPID controller and REBOOST DC to DC
Can you provide your mail plz
ashacademy01@gmail.com
@@TechSimulator
Thanks a lot sir, I send a mail to you sir please check out sir
why u have chosen the Vq and iq Reference constant Zero?
You can set the required voltage reference either as vd or vq. If you keep the reference in vd and keep vq zero, then voltage in the fiirst phase (that is VR) will align in phase with angle information(wt) that we are giving externally. If you keep vd zero and set the required reference in vq, then there will be 90 degree phase difference between voltage VR and angle (wt).
@@TechSimulator thank you kindly check your email
Ok
Sir How you have calculated that the rated power is 100 kVA? Kindly share formulae with us
You can choose whatever kva value u want to deaign. It is all upto you. I wanted to show you how to design 100kva. So i chose 100 kva.
Output results are not coming
you can mail your model
sir ,plz make a video for inverter controller design.
Sudipta Pany you mean a video explaining how to find pi controller constants.
@@TechSimulator
YES , SIR..
