You saved my day. Such a well-laid-out explanation. Thank you.
Thank you so much, this is amazing
such a teaching skill.. Amazing.
superb Sir,,,thanx a lot... plz release more videos for control system
Excellent explanation, chapter 8 of Yazdani’s “Voltage-Sourced Converters in Power System” book will cover the missing gaps in this lecture and shed light on the math.
Very nicely presented sir thanks a lot.
Dear sir, can you please make some videos on how to tune PI controller for these systems and also covering the hardware design and implementation of control topology on some real time plateform (either software or hardware). It will be a great help to the community.
Excellent explanation, I hope you are all right.
Very nice explanation sir! Thank you very much.
Dear Prof Umanand ji, it is a great presentation and explanation. I would like to know which software and system you use for writing, drawing circuits and narration recording and displaying.
Thanks for sharing....Prof. Mahesh Kumar, IIT Madras.
hi sir, I'm reading your papers from past 4 years. when DSTATCOM is operating as a VCM we need to generate reference voltages or reference currents.
And why CCM and VCM cant be achieved at a time.
Sir, your writing app is great. Can you share which app do you use for this digital board teaching?
Thanks
What program are you using for your diagrams?
Thank you!
Sir, How do we get voltage reference from Id & Iq using PI controller?
Sir please reply
Inner control will be voltage reference because the signal will trigger PWM gate driver that convert DC link voltage to be PWM voltage waveform
Thank you very much Sir.
awesome,, thanks, sir!!!
Why do you want the voltage and current vectors in phase having an angle of 0 degrees?
Because want to keep max power cos phi = 1 put to the grid
is bidirectional powerflow possible with this method?
It depends on the inverter topology, full-bridge inverters allow for bi-directional power flow, as oppose to half-bridge which only go one way
@@alawi0juventus hello! may I contact you somehow?
@@alawi0juventusif bi directional inverter like “active front end” , so how can power feedback to PV
Is impp constant ? As bcoz current at max power is provided by the manufacturer y compute it through mppt?
Because max current depends on solar irradiance
Professor, how can i tune controller gains..... In fact there is need for 4 controllers in statcom... How can tune them.... Can you suggest me articles?
Now I can sleep peacefully
sir,can you explain how we tune our PI?
Tune P part (first skip I) , increaseP until response start to oscillate, then reduce P to 30%, then open I part tune I part until rise time as fast as possible with only little overshoot
Sir, Please mention the reference books.
If i want to generate reactive power of my PV, what modification should i do?
May be control angle “rol” to cos rol according to the need reactive power
