The name of wind generator model must be 'REGCAU1'?

I'm writing a UDM wind generator model named 'REG' in .f90 and .dyr. However, When I load .dll, .dyr, and start the simulation, it shows 'USER DEFINED MACHINE MODEL "TEG" NOT ACCESSIBLE' in the output bar. While I change my UDM name to 'REGCAU1' and

@! Generic RE Converter model 2 'USRMDL' 1 'REGCAU1' 101 1 .../ Generic RE Converter model

in .dyr, my model works. But psse crashed when I open the model to see the values of CON and VAR. I can open and see when the name isn't 'REGCAU1'.

How can it happen that PSSE recognizes the name error or the name of generator must be a offical one?

Don't name your model REGCAU1! It must have a unique name.

A wind generator model is a current injection model (IT=1) and is called in both TBLCNC and TBLCNT. The subroutine REG is called in TBLCNC and the subroutine TEG is called by PSSE in TBLCNT.

Your model needs an entry point for subroutine TEG so PSSE can call it in TBLCNT.

Read about Coordinated call in POM.

Thanks for your reply!I wrote 'ENTRY TEG' in my model and there was no 'TEG NOT ACCESSIBLE' any more.But my model didn't work well, as I calculate ISORCE(MC)=CMPLX(10,-10) after ENTRY point.After initializing,the value of 'VAR(L)=ABS(ISORCE(MC))' is 14.14, but data is all zero in 'MACHINE INITIAL CO
