Simscape Power Systems Subsystem

Hi all,

I'm trying to condense a Three Phase Inverter into a Subsystem for implementation in a larger model. I was planning on having the input to my Subsystem be the DC Voltage Source and the output be both the bused Three Phase AC Voltage and AC Current Output. I used connection points for the two inputs and just Simulink outs for the Subsystem Outputs.

When I try and run my model, which I assume should work, I get the following errors;

 "Goto/From connections cannot cross nonvirtual subsystem boundaries. The only exception is when a goto is 
 connected to a state output port"

 "Invalid connection starts with 'Three_Phase_Inverter_FINAL_Subsystem/DC Voltage Source2/Goto'"

 "Invalid connection ends with 'Three_Phase_Inverter_FINAL_Subsystem/Subsystem/powergui/EquivalentModel2/Sources/From1'"

Following the Diagnostic Viewer takes me into the DC Voltage Voltage Source and the Powergui block, but I'm not really sure on the error at all, or why it isn't working like a typical Subsystem.

I'll attach my attempt at creating the Subsystem to create a better picture.

Any help in anyway is much appreciated.

Cheers, Ali.

The visibility of GoTo block does not cross non-virtual subsystem (i.e. atomic subsystems). You should convert the atomic subsystem to virtual subsystem if you want to pass data using GoTo blocks within the model.

"Goto/From connections cannot cross nonvirtual subsystem boundaries. The only exception is when a goto is

connected to a state output port"

"Invalid connection starts with 'Three_Phase_Inverter_FINAL_Subsystem/DC Voltage Source2/Goto'"

"Invalid connection ends with 'Three_Phase_Inverter_FINAL_Subsystem/Subsystem/powergui/EquivalentModel2/Sources/From1'"
