2013-04-01 02:07:04 -0500 asked a question how do I interpret the output y matrix?

Hey guys,

I want to get the admittance matrix from the network data in psse. I know there is a api called outputymatrix. But I find it difficult to interpret the result. The outcome sometimes even include the branches that don't exist in the first place. For example, I got

204010, 204010, 0.354998670518398E-01,-0.170381188392639

204010, 210004,-0.354998670518398E-01, 0.170381188392639

204009, 204009, 0.354998670518398E-01,-0.170381188392639

I understand that the first line should be the self-admittance of bus '204010'. Yet I couldn't find any branch between 204010 and 210004 on my raw file. In addition, I don't know what the third and fourth number mean in a line. Which is the admittance I want?

At last, what I want is actually an network impedance matrix. Does PSSE provide a API to extract the impedance matrix?

Many thanks!

Thanks. It works!

I have been trying to use python script to solve power flow problem using the pss/e module. When I finished the solving, I got windows showing the log of the solution, including the Siemens company introduction and the power flow result. Since I just need the results for post-processing, I find these windows very disturbing. Can somebody kindly tell me how to disable these windows?
