Partial model for all machines

Information

Base partial model DC machines: Besides the mechanical connector flange (i.e., the shaft) the machines have a second mechanical connector support.
If useSupport = false, it is assumed that the stator is fixed.
Otherwise reaction torque (i.e., air gap torque, minus acceleration torque for stator's moment of inertia) can be measured at support.
One may also fix the shaft and let rotate the stator; parameter Js is only of importance when the stator is rotating.

Partial model of three-phase transformer

Information

Partial model of a three-phase transformer, containing primary and secondary resistances and stray inductances, as well as the iron core. Circuit layout (vector group) of primary and secondary windings have to be defined.
Default values for transformer's parameters (a realistic example) are:
turns ratio n 1
nominal frequency fNominal 50Hz
nominal voltage per phase 100V RMS
nominal current per phase 100A RMS
nominal apparent power 30kVA
primary resistance R1 0.005Ohm per phase at reference temperature
reference temperature T1Ref 20°C
temperature coefficient alpha20_1 01/K
primary stray inductance L1sigma 78E-6H per phase
secondary resistance R2 0.005Ohm per phase at reference temperature
reference temperature T2Ref 20°C
temperature coefficient alpha20_2 01/K
secondary stray inductance L2sigma 78E-6H per phase
operational temperature T1Operational 20°C
operational temperature T2Operational 20°C
These values give the operational parameters:
nominal voltage drop 0.05p.u.
nominal copper losses 300W
