The control diagrams and differential equations of models

[Tang115]

Dr. Cui

I have the following questions:

1. Is there a document/source which summarizes the control diagrams of models (e.g. PSS, Exciter, and etc.) in Andes?

2. I am wondering that why TGOV1's differential equations look different in 3.10.1 and 8.31.2 of the ANDES Manual.

Thanks!
Best regard

Most models in ANDES are the same as that from PSS/E or Powerworld. You can search the model name and "Powerworld" to obtain the diagram.

TGOV1 was recently revised to use the convention in Powerworld and PSS/E. The figure in 3.10.1 is outdated. In that version, \Delta \omega was defined as (1 - omega), and now \Delta \omega is \omega - 1. Both models are correct.
