Thank you very much! What is the original theorem you used to calculate Kp and Ki
and what is the controllertime constants (my email is 2598269433@qq.com)Thank you very much again!
Sir I have started following your channel recently and have subscribed... You do a great job with apt explanation s...
Excellent video, info about calibration this kind of constants of controllers will be appreciated. I`m doing this simulation but with different values of filter and conditions. Maybe I build in physical prototype. If 100 people like this comment, I upload the result!
Thank you very much. great explanation
Such an excellent lecture!
Thank you
Hello, Thankyou for this beautiful video. it was quite helpful. Can you please share simulation file and reference paper/ document for it. So that we may be able to understand it more deeply. Thanks in advance!
Actually this video is awesome. Can you please make a video by including MPPT control to single phase inverter.That will really helpful for me.
if you knew how to include mppt control to this, could u share that fie
Thank you for this video. I request you kindly share details simulation of DPFC (DISTRIBUTED POWER FLOW CONTROLLER).
hi,
great video thanks
do you have any calculation for the Kp and Ki?
thanks.
thankyou so much, what i must to replace if i'm using a pv array with MPPT?
Hello, Are the parameters of the LCL filter suitable for the level of current harmonics generated in the network? Have you done FFT analysis in PowerGui?
Very nice presentation, thank you sir. How to find the values of kp,ki?
Also you mentioned in the video that we can use I grid instead of I inv, how we could do that?
Hello sir,, I have one doubt,, i think we have to compare reference current with Grid current not the inverter current... Please clarify my doubt sir
Hi, I wish to ask 1) Is the DC-link RC before inverter a must? and how to calculate the value? 2) Why each components of the LCL filter must contains resistor in series, how to determine the value of resistor?
Thank you for this video.
Is it possible to have both active and reactive power injected at the same time?
Thank you for this video.
Is it possible to have both active and reactive currents injected at the same time?
what is the value of the PI gains which u are keeping here?
Could You Please make a video on Bidirectional inverter control strategy?????
@Tech Simulator
Thank you Sir. I have a question, why add Vgrid after controller
Feed forward term
sorry, why the output of PLL is treated as the inverter current reference? I think its the grid current reference signal. Could you please explain to me? Thanks
Thank you for the video. How did you calculate the P and I values for the PI controller in the PLL?
trail and error
Hello, i have simulation of a single stage, single phase flyback inverter, feded by a pv array. The control is okay but the output current can't be in phase with the grid voltage, even i have a PLL controler but nothing works, with all the modifcations that i do current and voltage can't be in phase, current is lagging about 90 degrees, what can i do?? :(
Can we get in 3 phase inverter
Thank you sir for your effort, I have a question why do we use crurent contrôler (PR) ?
Pi controller is suitable for tracking dc quantities only. For ac quantities PR Controller gives better result. And when we control AC Quantities using PI controller, there always exist small steady state error. But by using PR controller, we can achieve almost zero steady state error
@@TechSimulator Can PR controller be used to control traditional single phase pfc rectifier, which use full diode bridge and one pwm controller to boost ?
Sir I am having doubt when Vdc reference and Vdc actual is compared and error voltage is fed to pi controller output current is produced can use explain about it.
what is the unit of omega^2/Kr ? is it only 986.8 ? what is the unit of it?
thanks for sharing. Any video about grid connected inverter using universal bridge to do the active power control? Thx
in this simulation you can replace the IGBTs with universal bridge, it will work
With this grid-connected inverter simulator, can we use it to grid a single-phase T-type inverter? If possible you can try a video. Looking forward to hearing from you.hihi
HI, can you please also explain 3 phase or single phase four quadrant Grid tied convertor?
what is the switching frequency?
Hello, I have done the same simulations getting the results but THD is 26%. How to overcome please tell me.
How do you set the switching frequency
Thank's; What is the original theorem you used to calculate Kp and Ki
and what is the controllertime constants
These are very valid questions need more explanation. I will include these details also in the document that i am preparing for you. I am quit busy now, will try to send the document within 2-3 days.
okay that's very nice of you, thank's
Sir please send me that document.
mayankamipara96@gmail.com
@@TechSimulator send me that document if possible
thank your share, how to calculate time constant
time constant can be take 1.5 to 2 times of switching time
At 5:28 you said that we take coswt from PLL to PR how to do that ??
simple connect the output of the PLL to the controller input or use "goto" and "from" blocks as shown in the simulation
Can I have this matlab file ?
From where the sinwt comes for reactive power?
Output of PLL
How can you say inject the real power to grid ?? Is real power can be altered in grid
Please watch this video. How a grid Inverter is generating Active and Reactive Current? Fundamental Concept explained.
@@TechSimulator as I tried a single phase inverter open loop model but its not working properly can u mail the model to ktvaeee@gmail.com
@ Tech Simulator ...Dear Sir, you say that the grid voltage and current are in phase in the simulation results but I see they are not in phase. Could you please let me know how to make both of them to be in phase?
by changing the value of inductance in the filter circuit
Could you please send the reference used to calculate the Kp and Kr parameters
Hlo sir can you plz do a video on power quality improvement using shunt active power filter based on pq theory.
It's very difficult to find n my simulation is not providing the required output. I need your hlp sir 🙏
Hello sir ,sir as you said here all values are taken from a paper so can you please send me that paper sir
How to find dc bus capacitor values?
how do you select the controller time constant
Current controller should be faster than voltage controller always. Therefore current controller time constant value should be less than that of voltage controller time constant value
I usually take current controller time constant as device switching time, and voltage controller time constant as 1.5 or 2 times the current controller time constant
If these values makes the system unstable, then you can gradually try to find increase these numbers
thank you, sir. Kindly let me know how to choose Kr because you took 100. for us how to take it.
Watch the video on “closed loop simulation of single phase stand alone inverter using PR controller” where i have explained how to select kr values. And one thing to remember is that, kr value can be different and controller will work fine for different values. In the method that i have explained will give the starting value of kr, if that value is not working , you can start reducing it
It is a lot to ask but can i get a m file for this simulation please?
you can make the model by watching the video. i will help if u r unable to get the correct output
Please I need a pdf or article talking about this simulation Please answer me I need it and thank you in advance
i didnt get what exactly you need
@@TechSimulator I need the article or pdf talking about this simulation (single phase grid connected inverter using MATLAB sumilink ) my email is:
talha53828@gmail.com
Hello sir, i need droop control of inverter simulink file
i dont have
Can you make a vedio on that
@tech simulator pl share the reference paper for this.
i made the simulation myself, didn't refer any paper. if i get a proper paper, i will leave the link here.
Can u share this matlab file?
No
