Abstract
A method keeps a synchronous machine in a stable operating zone during large transient voltage excursions on a power grid to which the machine is connected. The machine's load angle, i.e., the position of the rotor flux with respect to the position of the stator flux, is calculated. If the load angle is not within a defined range of reference values for stable machine operation, the machine's field excitation is adjusted to bring the machine's load angle within the defined range of reference values for stable machine operation.
