摘要： An adjustable speed gas turbine power generation apparatus can maintain a rated output of the gas turbine generation apparatus irrespective of ambient temperature change. For this purpose, the rotational speed of the secondary winding of the generator is controlled by the gas turbine and alternating current excitation of the secondary winding is determined on the basis of the ambient temperature. The sucked air quantity (flow rate by weight) in the compressor can be increased by increasing the rotational speed of the gas turbine when the ambient temperature increases, so that an output from the gas turbine becomes nearly the rated output, while maintaining the desired frequency at the primary winding.

摘要： A line power unit controls electrical power delivery to a grid from a three phase permanent magnet generator. A line power unit controller receives a power level command and controls a main inverter that draws DC power from a DC bus to deliver the commanded power to a grid. The DC bus is fed DC voltage via a three phase permanent magnet generator and a rectifier. The inverter delivers power to the grid via a filter, transformer and main contactor. The line power unit controller also controls the main contactor to break the connection with the grid. A precharge circuit draws power from the grid to precharge the DC bus to a precharge voltage. Alternatives include a start inverter separate from the main inverter that permits simultaneous delivery of power to the grid and commutation of the permanent magnet generator as a motor to spin an engine connected thereto at a speed sufficient to permit engine starting. Another alternative utilizes a single inverter for engine starting and power delivery which does not permit these operations to be simultaneously performed. Further alternatives include eliminating the transformer by utilizing a high-voltage rated main inverter.

摘要： A control device for a motor vehicle electric generator takes into account the relationship between field currents flowing through field windings of charging generators having different generation powers and output currents. The field current is increased once and instantly at the time of loading but prior to suppressing the increasing speed of the field current. The amount of the increase of the field current is controlled to be proportional to the field current before the loading. The control device according to the invention can be used for charging generators having different power generation capacities, and the battery voltage drops at the moment when switching in a motor vehicle electric load are reduced to substantially the same level.

摘要： The excitation current in the rotor winding of a motor vehicle alternator is regulated by this method. The alternator produces a rectified output voltage to be regulated, this output voltage being a periodic voltage having a period T consisting of a first phase T.sub.1 in which the battery voltage is applied to the rotor winding, and a second phase T.sub.2 in which the battery voltage is not applied to the rotor winding. The method includes: measuring the rectified voltage by sampling during each period T; comparing the measured value with a calculated reference value; and deducing from this comparison three numerical values. The first of these corresponds to the difference between the measured value of the rectified voltage and the reference value. The second of these numerical values is a closed loop excitation value calculated in each period T by adding the corresponding value measured in the preceding period to the first numerical value, to which a first correcting factor is applied. The third numerical value is an open loop excitation value calculated, in each period T, by adding together the closed loop excitation value already calculated in the same period and the first numerical value, to which a second correcting factor is applied. The duration of the first phase of the rectified voltage is determined by the value of the open loop excitation.
