modelPartialBasicElectricMachine2phPwr_wBalance
Extends from PartialBasicMachine (Basic model for generalized electric machines).
Information
This partial model is an extension of the model of a generalized electric machine
PartialBasicMachine.
Hence, it consists of the same mechanical subsystem.
The model defines a two-phase machine.
The electrical subsystem contains four electrical pins of type
ComplexPin.
The rms values of the branch voltages and branch currents are calculated from the
corresponding phasors.
The model does include the current phasor balance.
Therefore, models being extended from PartialBasicElectricMachine2phPwr_wBalance
must not contain any internal electrical components.
The behaviour of such models has to be defined by equations.
Two values of active and reactive power (for each branch)
are computed and made available via two output signals.
Remark:
This partial model is suitable only for modeling two-phase machines.
