Modelica.Electrical.Polyphase.Examples.TransformerYY

Test example with polyphase components

Information

Test example with polyphase components:
Star-connected voltage source feeds via a Y-Y-transformer with internal impedance (RT, LT) a load resistor RT.
Using f=5 Hz LT=3mH defines nominal voltage drop of approximately 10 %.
Simulate for 1 second (2 periods) and compare voltages and currents of source, transformer and load.

Parameters

Modelica.Electrical.Polyphase.Examples.Rectifier

Test example with polyphase components

Information

Test example with polyphase components:
Star-connected voltage source feeds via a line reactor a diode bridge rectifier with a DC burden.
Using f=50 Hz, simulate for 0.1 second and compare voltages and currents of source and DC burden, neglecting initial transient.
We may also compare: Active power measured by powerSensor, powerSensorSpacePhasor and aronSensor, as well as reactive power measured by powerSensorSpacePhasor and reactivePowerSensor.

Demonstrate a polyphase diode rectifier

Information

This example demonstrates a polyphase system with a rectifier per subsystem.

Note that the interaction between the subsystems is damped by the DC resistors and inductors.

You may try different number of phases 2 ≤ m, as well as connect the rectifiers with different number of parallel branches, and investigate AC values:

• AC power analysatorAC.pTotal (sum of all phases)
• AC current analysatorAC.iFeed[m] (1st harmonic rms)
• AC voltage analysatorAC.vLN[m] (1st harmonic rms, line to neutral)
• AC voltage analysatorAC.vLL[m] (1st harmonic rms, line to line)

as well as DC values per subsystem (rectifier) and total (load):

• DC power total analysatorAC.pDC (mean)
• DC current total analysatorAC.iDC (mean)
• DC voltage total analysatorAC.vDC (mean)
