This method you can implement to any active filter Shunt or Series to compensate non linear current, First take source with non linear load, and measure line current apply this technique to converts three phase to two phase reference frame, it will gives you final error signal which you can process further to create PID or Hysteresis.
Sir! what is the purpose of the input(in1, in2 in3 in4) and output block? and i was wondering why the lecture is on one side and the cursor pointing is one the other? thank you!
Thank you for feedback, About your question regarding one of block after ABC to PQ converter, in1 , in2 and in3 and in in4 these are the multiplier for reverse transformation, For example if you convert any ABC to alpha beta then it also goes to unity output due to matrix multiplication and after that if you need your original values in reverse transformation for alpha beta to ABC so Va and Vb magnitude is taken for multiplication as a original values so that magnitude of all phases can be identified and reverse transformation is done. While editing this video voice is leg it just mistakes while rendering this video.
@@SUNInnovative Thank you for your reply. What i got is- first u converted ABC to alpha-beta then calculated ins. power p and q then u got alpha-beta again using the block (the question is: how the product block has been used to get alpha-beta volts and amps) and using inverse clark u got ABC back. and how is the compensated signal achieved . As far as i know, it should involve the comparison of the desired signal with the measured signal.
Dear, If you watch this video again you will be find that in subsystem of products we made for voltage and current after instantaneous calculation by alpha and beta, there is gain is connected at signal "in4" with value of "-1" in which it will act as reverse quantity of non linear line current and due to this negative polarity if you got your signal back to ABC and putting one ADD block so it will perform as compensation = Va - Ia Va act as reference signal as Sine Ia act as non linear line current And having gain with negative will make equation as a subtraction. Hence you will get compensated signals at output. We refer to all our subscribers to watch our video in full length and sometime 2 times watch this because we given every answer in video it self. Thank you for watching our videos, still if you having doubt please feel free to ask anytime.
@@SUNInnovative hi sir. very helpful video. Great work. Sir kindly it's request kindly get me the code of abc-alpha beta and abc to dq transformation. i will be very thankful to you. inams5379@gmail.com is my email id. Thanks
You are amazing mannnnnnnnnnnn! you are awesome!!!!!!!!!!!1 you are a true hero!!!!!!!!!!!!!!!!!you rock it
Thank you for supporting
Super explaination. Excellent
Thank you
Very nice video
Thanks
Brilliant video !!!!
very useful video can i get ideas to work on dq model for switched reluctance motor
nice work.. sir
Good explanation but once I see the discription there is no code or simulink file were attached.
You need to join our channel.
This Video is now available with different languages subtitles.
no problem sir.
Do you have chinese subtitles? thanks
Nice explain
Can you elaborate the 3 phase PLL block? I'm trying to transform grid abc currents and voltages into dqo frame and I need the angle.
Next time please create and show the blocks
your website is not opening
Very helpfull video..
Can you please explain how I can use this pq design for active filtering.. ?

Sir how u got magnitude=1 for all the three graphs abc,alpa beta,dq

very helpful.can u check my model in dqo transform
Send to us.
Sir if I have separate 3sinwt and 3coswt how can I have phasor practically
Can I get the code for plotting the rotating axis along with the frame? It will be very helpful.
Please send email to us

Should we write the code
can you share all these simulation files with me ??
it will be very helpful
i am using the transformations for active power factor correction
Check description

Please be wait for reply. We will get back to you soon
The link won't load can you help?

Thanks for the video. It would great to stop the distracting background music.
Noted!
why the filter is kept at 25 hertz sir
why didn't you show alpha beta to dq block?
Because it's a matrix block only, and also available in Simulink library there is no any secret parameters.
How to insert matrix in abc to alpha beta zero
Sir....can u send this matlab file.......I would be very much thankful to u sir....
Email to eoyinnovative@gmail.com
i need this file please sir send me quotation.
where is experimental lab ?
I dont understand .
لي فهم يجي يفهمني مافهمت والو
too many ads
Can pl stop the bloody music in back.ground..and this sound of ghanti...why ??it is not a film.going on..
