Synchronous machine in simscape specialized power system with isolated starpoint !

In MATLAB Simscape specialized power system the synchronous machines comes with the three-phase supply without any neutral point pin outside. In the description of the block it is mentioned about internal neutral point. Is there any way to get a isolated starpoint instead ?

Hi @Friedrich Schmidt,

While reviewing the Simplified Synchronous Machine documentation, it was found that the neutral wire can be exposed by setting the parameter Connection Type to 4. More details about this can be found here:

Hope this helps !

Hi Swastik, Thanks a lot for your answer! :-) I use not the simplified models but the full featured models synchronous machine pu standard synchronous machine pu or si fundamental Friedrich

Hi @Friedrich Schmidt,

I had gone through their documentation too, but I did not find the mention of "internal neutral point" in the description of the block, could you please link the part which specifies this ?

Hello Swastik!

Thank you for your answer and sorry for my late reply. You can see the information for the neutral point in the parameter dialog for the synchronous machine block ( first two lines above ) !

Regards,

Friedrich
