Description:	MVA base for AC line parameters.
Detail:

Transmission MVA Base is used to scale the per unit (p.u.) reactance and resistance back to megawatt values. By default, the MVA base is 100, i.e. a flow of 100 MW is equivalent to a 1 p.u. flow. For example, a 250MW, 275KV transmission line may have a resistance in the order of 0.02 p.u. and a reactance in the order of 0.05 p.u. using a 100 MVA base. Internally, a Voltage Base of 1kV is assumed and these p.u. figures are scaled using the MVA base so that modelled flows and losses are in megawatts.
