Quantization Index Modulation using the E 8 lattice

Regulator apparatus for a synchronous machine having a field winding, and terminals connected to an electrical system. The regulator apparatus utilizes the power factor at the terminals of the synchronous machine to control the excitation of the field winding during normal circuit conditions, and the voltage at the terminals to control the excitation during system voltage disturbances.
