Resumen
System and method of limiting the armature current in case of a defect in synchronous machines (2) excited by a voltage regulator (3). The method includes: - measuring the current of each one of the phases of the armature of the synchronous machine (2); - if the armature current i of one of the phases of the synchronous machine (2) is greater than an activation threshold of the limiter ilim on, activate a limitation process of the excitation current of the synchronous machine (2) by which an error regulation (18) is made between the armature current i and an armature current limit value ilim and the regulated signal is subtracted from the voltage of setpoint (10) of the voltage regulator (3). The limiting process can be deactivated when the armature current i falls below a limiter deactivation threshold ilim off. (Machine-translation by Google Translate, not legally binding)
