Question:

What are the differences between the old EMTP type 59 machine and the EMTP-RV synchronous machine model. 

Answer:

EMTP-RV synchronous machine  enhancements :
 
  1. It iterates with the network so it is much more numerically stable for larger time-steps;
  2. It offers saturation modeling on both axes,
  3. It has a much better predictor method.
