Abstract: A brushless synchronous machine with a limiter for main field voltage and a method of limiting main field voltage in a brushless synchronous machine are described. The machine includes a regulator to use a field current to excite main field windings and generate the main field voltage. The machine also includes a limiter to limit the field current to maintain the main field voltage corresponding to the field current below a limit based on a transfer function.

Abstract: Systems and methods for monitoring excitation of a generator based on a faulty status of a generator breaker are provided. According to one embodiment, a system may include a controller and a processor communicatively coupled to the controller. The processor may be configured to receive, from a contact associated with a generator breaker, a reported status of the generator breaker, receive operational data associated with one or more parameters of a generator associated with the generator breaker, and correlate the reported status of the generator breaker and the operational data. Based on the correlation, the processor may establish an actual status of the generator breaker, and, based on the actual status, selectively modify a mode of excitation of the generator.

Abstract: A method for initializing a generator may include sending a field reference voltage to an exciter that may provide a direct current (DC) current and a DC voltage to a rotor of a generator based on a current set point that corresponds to the field reference voltage. The method may then include receiving a voltage feedback signal output by the generator, determining one or more locations of one or more poles of the generator based on the voltage feedback signal, and sending one or more firing signals to one or more switches of a starter after determining the locations of the poles, such that the switches couple the voltage to a stator of the generator.
