Dear All,
we are trying to translate the matpower casefiles to pandapower but have encountered problems when converting cases with transformers. We would expect transformers always to behave inductive, but the transformer branches in the cases always seem to have a positive b value. If I am not mistaken, that models a capacitive behaviour. An example of this can be found in case118 with the branches that connect buses 68 (345 kV) and bus 116 (138kV) as well as a branch that connects bus 86 (138kV) and bus 87 (161kV). Both of these branches have a positive susceptance while connecting different voltage levels. Is there an explanation for that, i.e. do these branches not only model a transformer but a whole substation with reactive power compensation device as well? Or am I missing something else?
