modelFREQ_CTRL

Voltage frequency control used in resynchronization

Information

This frequency controller, which is based on simple PI, is used to reduce the error (ideally to zero) of the voltage frequency difference between two different nodes in the system.

After the difference is reduced to zero, and the errors on voltage magnitude and angle are also zero, the two nodes can be connected without major issues.

Note that this system uses the Frequency Calculator system.
