Hi, may i ask whether the value of additional time delay for mechanical movement of the relay contact is fix at 0.02 sec or not?

[@DrJALAGHARI]

In this program, it is fixed.

[@htheh7728]

Can i have the data sheet of the protection relay that you used?

[@DrJALAGHARI]

Thanks for the comment. I have provided the link in the descirption section of the video. You may kindly download it.

[@MuhammadMurtaza-b2u]

sir how i can combile all of these like over/under Volatge , o/u Current and o/u frequency in one model

[@DrJALAGHARI]

Thanks for the comment. I am not sure but this may require to create new component and combine all codes in one block.

Hi.i need to simulink "Overvoltage Protection by Lightning for a Grid-tied Solar Power System" can you help me plz

[@DrJALAGHARI]

Thanks for the comment. I am sorry I haven't worked on this topic. You may kindly go through MATLAB file exchange website to find any suitable model if available.

[@UmarKhan-st1qd]

Sir please try to make simulation of solid state relay

[@DrJALAGHARI]

Thanks for the comment. Ok I will try to make video on this topic very soon.

[@UmarKhan-st1qd]

@@DrJALAGHARI sir please mention time i really need this within 2weeks

[@DrJALAGHARI]

@@UmarKhan-st1qd Within this time may not be possible. It needs lot of time to find some paper to get the idea then model it in MATLAB then simulate it. It takes more time. Don't wait for this video within this short period of time.

[@andrehebad9881]

assalamu alaikum sir,, can i ask you something,,, can i join in one simulation,, i mean modeling over voltage with under voltage in one simulation thanks

[@DrJALAGHARI]

Wa'alaikum salaam i am not sure but you may try it. May be it works.

[@andrehebad9881]

@@DrJALAGHARI thanks sir,,, if i found any problem can i contact you sir ?

[@mohannanda1089]

Bro which MATLAB version it is

[@UmarKhan-st1qd]

Sir this is not correct simulink in link description

[@DrJALAGHARI]

Thanks for the comment. I couldn't understand your comment. Can you please explain again ?

[@UmarKhan-st1qd]

@@DrJALAGHARI this is not correct file in description your video is about over voltage relay butt you upload frequency relay simulink file in given link please upload right file in description

[@DrJALAGHARI]

@@UmarKhan-st1qd Thank you so much for highlighting this mistake. I have inserted the correct link. Now, you can download the over voltage relay Simulink model.

[@UmarKhan-st1qd]

@@DrJALAGHARI sir i have mail you a circuit of over/under voltage relay sir please implement as soon as possible

[@UmarKhan-st1qd]

Sir i have a circuit diagram of hybrid energy system i want to send it to you then you implement on matlab then upload video

[@DevendraSingh-jm2ys]

Sir can u tell how to design directional relay?

[@DrJALAGHARI]

Thanks for the comment. At the moment, i am not clear how to model it. I will try to go through few papers and try to make video on it as soon as possible.
