Abstract: A controller employed in conjunction with a synchronous generator monitors the output voltage of the generator. The controller employs the monitored output voltage as feedback that is used to control the excitation provided to an exciter field winding. In addition, the controller applies a control loop to the monitored output voltage that detects and modifies voltage ripple signals within the monitored output voltage to generate a compensated signal that is used to control the excitation to the exciter field winding. In particular, by detecting and modifying voltage ripple signals within the monitored output voltage, the controller is able to counteract armature reaction voltage ripples caused by unbalanced short-circuit faults, thereby preventing the build-up of voltage on the DC link.

Abstract: An excitation system for a brushless generator includes an exciter portion having a set of polyphase exciter field windings and an additional exciter field winding disposed in a stator of the generator, a source of polyphase, constant-frequency AC power and circuitry coupled to the set of polyphase field winding for connecting the source of polyphase, constant-frequency AC power thereto at a beginning of operation in a starting mode whereby AC power is induced in an exciter portion armature winding by transformer action. AC power is further provided to armature windings of a main generator portion to thereby cause a rotor of the generator to accelerate. An autotransformer is provided to reduce the voltage provided by the source of polyphase AC power prior to application of such power to the polyphase field windings so that the need for an auxiliary inverter is obviated. Thereafter, at least one of the windings of the set of polyphase windings is connected in series with the additional field winding when the speed of the rotor reaches a predetermined speed and a DC current of controlled magnitude is delivered to the series-connected exciter field windings to thereafter allow operation in a generating mode.

Abstract: The invention relates to rotating alternating current generator systems. Generator excitation is normally controlled by varying the field current to the exciter. An SCR rectifier circuit responsive to exciter output voltage normally provides controlled direct current for the exciter field while a diode rectifier circuit responsive to exciter output current provides direct current only during transient conditions when the exciter voltage may be low. The current boost diode rectifier circuit is coupled to current transformers located in the exciter output lines. The current boost circuit including the current transformers is designed to take advantage of the characteristic of most alternators that its short-circuit excitation requirement is considerably less than its rated-load excitation requirement, for the same alternator line current. Some exciters, notably salientpole alternators, do not have the large separation between the short-circuit excitation condition and the rated-load excitation condition. Thus, it is difficult to design current transformers with a ratio low enough to insure that the current boost circuit will be regenerative under short-circuit conditions, and yet with a ratio high enough so that the current fed back will not interfere with the exciter field current supplied by the SCR circuit under normal operating conditions. A static switch, of unique design, is provided to insure compatibility between the SCR circuit and the diode rectifier circuit under normal operation, and yet permit the current feedback to be sufficient to support an exciter short circuit, regardless of the separation between the short circuit and rated-load circuit excitation conditions.
