So, the matter is that I've modeled a system that deals with 9 transmission lines in Power System Computer Aid (PSCAD) Program.
but, when I put Multi-meters between two sides of transmission lines the calculated P,Q and V differs from each other far behind the desired amounts comparing between putting a Wire between the buses instead.
I've tried PI and Overhead Transmission lines(Bergeron Model & Frequency dependent) but no differences.
The Question is that What should I do in order of getting the same values before and after the transmission lines.
Thanks a lot.
I didn't understand properly but as per my opinion the parameters and tower selection are important in case of a transmission line .Have you placed all things properly ?
Which version of PSCAD you are using that I don't know , but I will suggest you to calculate P,Q from Voltage and current samples by using FFT block . I hope it will give you your desired result.
Note: I have 4 Generators, 3 of them supplies the load with appropriate generation but the smallest generator goes to the motor mode( the generation amount of power is negative p.u and is very small compare to others, 0.3 p.u for instance.)
I can't figure out the problem.
