A high voltage DC electric power generating system includes a poly-phase permanent magnet generator having at least one control winding and a plurality of power windings. Each of the power windings is a phase of the poly-phase permanent magnet generator. A passive rectifier connects a switch to an input of each of the power windings such that the switch is a neutral node in a closed state and a disconnect in an open state.

An output of a generator may vary according to the speed of the engine, physical characteristics of the engine, or other factors. A profile for a generator that describes a periodic fluctuation in an operating characteristic for the generator is identified. A field current of an alternator associated with the generator is modified based on the profile for the generator in order to counter variations in the output of the generator.

A power system may include a power generation component and a sensor configured to measure a parameter. The power system may also include a controller in communication with the power generation component and the sensor. The controller may be configured to run the power generation component in an exercise mode for a duration. The duration may be based on the measured parameter.

The method of control according to the invention slaves a DC voltage generated by the alternator to a predetermined setpoint value by controlling an excitation current flowing in an excitation circuit comprising an excitation winding of a rotor of the alternator. The excitation current is controlled by means of a semiconductor switch, in turn controlled by a control signal having a predetermined period. The method comprises a detection of a failure of the excitation circuit. At least one short-circuit of the excitation winding is detected. According to another characteristic of the method, the control signal is generated on the basis of a combination of a setpoint signal formed by pulses of the predetermined period exhibiting a duty ratio representative of the setpoint value and of a detection signal indicative of the short-circuit.

The gas turbine power generation system has a dual-shaft gas turbine, an electric generator mechanically connected to a low pressure turbine of the dual-shaft gas turbine and electrically connected to an electric power system, a rotary electric machine mechanically connected to a high pressure turbine through a compressor of the dual-shaft gas turbine and electrically connected to the electric power system, wherein a power oscillation is suppressed by operation of the rotary electric machine as a motor or as a generator.

A controller-integrated rotating electrical machine incudes a rotating electrical machine and a control device. The rotating electrical machine is equipped with a stator and a rotor. The control device is equipped with a control circuit for an inverter circuit and an angle position sensing device which works to measure an angular position of the rotor. The control device has first substrate on which the control circuit is mounted and a second substrate on which the angle position sensing device is mounted. The first substrate is located closer to the rotating electrical machine than the angle position sensing device is in an axial direction of the controller-integrated rotating electrical machine. This minimizes adverse effects of magnetic flux, as generated by the rotating electrical machine, on operation of the angle position sensing device, thereby enhancing a measurement accuracy of the angle positon sensing device.
