How to Design Inverse Definite Minimum Time (IDMT) Relay Model in SIMULINK | Dr. J. A. Laghari

[@AliKhan-hm1yx]

Aoa respected sir ur contribution towards the Ms and PhD students in tremendous. Please also make a video on design and modeling of distance relay for transmission lines .

[@DrJALAGHARI]

Thanks for the compliments and suggestions. I will try it.

Masha Allah Sir very nice

[@DrJALAGHARI]

Thanks for the compliments.

Assalamu alaikum sir I unable to download over and under frequency as well as idmt relay.please help me.

[@DrJALAGHARI]

Wa'alaikum salam thanks for the comment. Send email to [e-mail]. it will be sent to you.

[@asmaahassanein724]

would you kindly do a video on digital distance relay ?

[@DrJALAGHARI]

Thanks for the compliments and suggestions. Basically every new technique needs new learning and implementation. I will try if possible i will make a video on it.

[@emadeldeen2200]

sir this model is only for specific numbers of TMS values but what if I need to insert a 0.231 value for TMS ?

[@DrJALAGHARI]

Thanks for your query. The TMS are constants for every relay from 0.05 to 1. You cannot change it.

[@emadeldeen2200]

@@DrJALAGHARI sir I m working in my master and my task is to make optimization for the TMS values for IDMT, the results I got contain these values 0.124,0.204,0.332 and 0.117 this model is not suitable for testing my results

[@DrJALAGHARI]

@@emadeldeen2200 in practice, TMS are fixed as i mentioned. Therefore, if you want to change the TMS, you have to design completely new relay in the market. In that case, this model may not be helpful for you.

@@DrJALAGHARI i did it, I made a moodel witn user defined function. With its inputs are Tms, and i setting. It calculate the tripping time. Then send a trip signal to open the CB But i hav a problem. That after the cb opened, the time is reset again, how i can display the trip time even after the cb opened. How to take this value and display it,

[@DrJALAGHARI]

@@emadeldeen2200 i think you may go through the matlab function block of idmt relay. May be you get some idea how its settings are made through m-file.

Can I get file 2018a Version.

[@DrJALAGHARI]

Thanks for the comment. It is better to run it in its own version. Otherwise, it may give error.
