Abstract: A starting circuit, intended for an alternator with auxiliary rectification bridge feeding a regulator that controls the excitation winding by a transistor, while a warning light is connected in series with the contact key, makes it possible to have a high excitation current, as soon as the key is turned on for starting the engine. For this purpose, a stabilized power supply is connected by a diode to a point (A) located between the warning light and a transistor for control of the latter from a comparator; this point (A) is connected by a resistor to the auxiliary terminal (+A) of the alternator, which is connected by another resistor to the base of the transistor for controlling the excitation winding which is connected between the main terminals of the alternator. The base of this transistor is also connected to the regulating comparator fed by said stabilized power supply.

Abstract: In an electrical power generating installation which includes a plurality of turbine-generator sets, a parking bus is disclosed, which is provided with a potential regulated at a relatively low and constant frequency of the order of 1-2 Hz. Switching and phase and frequency matching means are provided, which enable the same controlled variable frequency starting system used for start-up of the turbine-generator sets, to be used for gradually adjusting the rotational speed of a selected turbine-generator set to a point where phase and frequency may be matched with that of the parking bus, to then permit the generator member of such set to be electrically transferred to the bus. By means of such arrangement, any number of turbine-generator sets may be connected in parallel to the parking bus which thereupon effects a simultaneous, continued low speed rotation of the sets for cooling or other purposes. The sophisticated, complex, and costly start-up system, is thus freed of any requirement for continuing rotation of the sets during the long cool-down period, whereby in typical installations but a single such start-up system is required.

Abstract: A capacitor is connected in circuit with the output windings of an alternator in such a manner that it is charged in a first direction during selected half cycles and in a second direction during the other half cycles of the alternator alternating current output potential. During the selected half cycles, the alternator output potential and the charge upon the capacitor acting in series aiding relationship provides base drive current for a driver transistor to trigger this device conductive through the current carrying electrodes. Upon the conduction of this transistor, base drive current is supplied therethrough to another transistor included in an associated voltage regulator circuit to trigger this device conductive through the current carrying electrodes thereof which completes an energizing circuit for the alternator field winding.

Abstract: The instant invention describes a starter-generator arrangement in which a dynamoelectric machine such as a synchronous machine is driven as a brushless DC motor to start a dynamic load such as a jet engine and as a synchronous generator after the jet engine is ignited and brought up to speed. A plurality of cycloconverters utilizing phase controlled rectifier banks are operated from a constant frequency supply source to supply current to the armature windings of the machine. Conduction of the rectifiers is controlled by position sensing elements such as Hall generators, the outputs of which are utilized to generate enabling signals to control conduction of the phase controlled rectifiers to supply current to the proper windings of the synchronous machine armature so that the synchronous machine functions essentially as a DC brushless motor which drives a dynamic load such as a jet engine. As soon as the jet engine comes up to speed, the system is converted and the phase controlled rectifier banks are operated from the output of the synchronous generator to produce a constant frequency 400 Hz output from the varying output of the variable speed generator driven by the jet engine. The system takes advantage of the fact that power can flow through a cycloconverter in either direction by selectively triggering the phase controlled rectifiers either in response to a varying input signal from a dynamoelectric machine operating as a generator and a fixed frequency reference source, or in response to a constant frequency supply voltage and signals representative of the machine rotor position to supply current to the proper armature windings of the machine to provide operation as a motor. The machine thus functions both as a motor and a generator with a minimum total parts, minimum reconnections with a change of modes and a maximum commonality of components.

Abstract: Apparatus for starting up the turbine of a gas turbine unit or a pump storage unit having a generator coupled to the turbine, which includes a frequency converter of variable output frequency which connects a supply voltage to the generator during start-up. The generator is accelerated by the frequency converter as a synchronous motor until a predetermined speed is reached. The frequency converter is a static semiconductor converter. The starting-up apparatus eliminates the need for providing a separate starter motor for the turbines. According to a further embodiment, the semiconductor converter includes a speed control arrangement for maintaining the generator shaft at an adjustable, desired speed until the turbine unit is either accelerated by the frequency converter to the predetermined speed or is further decelerated or stopped. The speed control arrangement avoids the very rapid accelerations and decelerations of the turbine shaft otherwise accompanying start-up and shut down, thereby preventing distortions in the turbine shaft caused by non-uniform heating and cooling.

Abstract: An arrangement for causing a desired full output voltage to be produced from a generator at a lower generator speed than is possible as a result of self buildup wherein means are provided to detect when the generator armature is rotating and for causing the generator to be separately excited from a source of direct current, such as a storage battery connected to be charged from the generator, whenever the generator armature attains a preselected speed, which speed is much lower than the normal operating speed.
