ObjectStab.Base

Information

The base package contains definitions common to all
subpackages, including the new datatypes for the p.u. 
quantities are defined.
 
The constant f0 sets the rated frequency. 
This can be changed into 60 Hz for american users.

ObjectStab.Base.Pin

Information

The electrical connectors of ObjectStab models are modelled by the voltages and 
currents in phasor representation:

I =   ia + j ib 
V = 1+va + j vb

The constant one has been introduced in order to help the initial value solver.
Two connected Pins results in the following equations:  

Pin1.va = Pin2.va
Pin1.vb = Pin2.vb
Pin1.ia + Pin2.ia = 0
Pin1.ib + Pin2.ib = 0

By definition, currents are considered positive when going into a component.
