Negative Voltage MPLOT

Hi there,

I'm fairly new to the software and have been doing some analysis on EMPT using a frequency dependent model. I was wondering if someone could explain or refer me to a paper/journal/book, as to why I see negative voltage plots using this method and only positive voltages when using a constant parameter model. Does it have to do with the initial conditions on each phase (ie 1.1pu of say 118, -59, -59) and a negative polarity surge (ie connecting -ve end of current source to the system)

Cheers
