Where did you add P=5000W and Q = 3500VAR in your data, it is not in the data you posted? If I remember well the default MVA base in MatPower is 100MVA; your P and Q data seems to be in W and VAR . Also, if I remember well, if you specify 0 for Pmax and Pmin and Qmax and Qmin there will be no limits on P and Q.
It seems that you need to read the MatPower Users Manual and look at the case files that come with the package. The User's Manual has very good description of the data format used.
