Line parameter of IEEE 1st benchmark confuses me
The line data really confuse me. For example, in the paper x1 = 0.06 and R1 = 0.02 and there should be x1 / R1 = 3 regardless of per unit or nominal or any base value. However in the simulation file L1 = 51.78 mH and R = 6.0832, the L1 * 120pi / R = 3.2089 > 3. And in the paper xc = 0.371, there should be xc / R1 = 18.55. In the simulation file, C = 21.977e-6 and 1 / (120pi * C) / 6.0832 = 19.8412 > 18.55. It is always a bit larger and there is even 3.2089 / 3 = 1.0696, and 19.8412 / 18.55 = 1.0696 as well, which looks very regular. I really dont know why and the difference in parameter really confuses me. Could anyone help me with this ? Thank you.
