Hello Akash You might want to try the function *Losses=get_losses(results) . *It computes branch series losses and optionally also returns reactive injections from line charging as functions of bus voltages and branch parameters. Thanks, On Sun, May 14, 2017 at 4:02 AM, Akash Tyagi

Assuming 101 is the row number in the mpc.bus array for bus 101: define_constants; mpopt = mpoption('out.all', 1, 'verbose', 2); mpopt = mpoption(mpopt, 'cpf.stop_at', 'FULL', 'cpf.step', 0.2,’cpf.plot.bus’,101); mpopt = mpoption(mpopt, 'cpf.plot.level', 2); mpcb = loadcase('Case_04'); % load

Below is the attached file of the results of the case9ab. The values for P (MW) are calculated by PF and PT. My question is how Q(MVAR) LOSS is calculated in the attached file in the last column, Is there any formula to calculate the the Q? On Sun, May 14, 2017 at 2:15 PM, Akash Tyagi

The results are still not coming. I have run the normal power flow and then see the values in the command window. P(real power loss) is calculated by PF and PT by the following command- real_power_loss=results.bracnh(:,PF)+results.branch(:,PT); The results are same as given in the command window

Hi Akash, is it possible that the problem is with the shunt capacitances. I suggest you calculate the line currents (from ohm's law) and then Qloss = X*I^2. regards Od: bounce-121528073-78499...@list.cornell.edu [bounce-121528073-78499...@list.cornell.edu] v

Reactive power Loss

2017-05-14 Thread Akash Tyagi
Hello everyone, I am working on my project and I got stuck with reactive power loss. I was trying to calculate the reactive power loss for all the branches. I have given the following case below- I run the normal power flow for the case attached below by the following command- << runpf (case9ab)
