Three phase energy meter (Harmonics included too) “C” Code

zzzzzzzzzzzzz

Need some formula my friend That might be a good start

Dear Friend,
What do you mean by formula..???
I need "C" code that could measure three phase energy..
Please tell me if you have some solution or mail me @
tahir.uet09(_at_)gmail.com

.i have also the same project as ur's....so can u plzz help me in this project....i wrote the code for tarrif calcultion bt not excatly if u have have then plz guied...
thanx aloot...

...

Hi you must have some idea as to how you would go about this and how you would measure this then you if not knowing how to programe in C would then be able to submit sometype of theory so as people might assist you

yes i have some idea how to write the code in c n also write this code bt it is not proper ..to complete this code i need some help.....like i want to calculate the peek and off peek tariff which range is 100-200...

AOA

I am designing three phase energy meter for linear or non-linear loads i,e even there are harmonics in the system the power (Real and reactive) will be measured by the meter..I am measuring up to 100 harmonics. i,e up to a 5-KHz frequency component.

I need some guide or simply algorithm showing how to proceed or build the code.

Thanks!

Lets see what you have and could you also provide a flow chart please Otherwise I’ve got to page through lines and lines of C code and try to decipher what your algorithm is in the process

I prefer to make life easier not harder and when answering questions or attempting to be of service I do need some participation from yourselves


Cheers

m writing this code for tariff calculation.....bt it gives some erors and use microc for compiling
