    Abstract: A starting system may include a wound-field electric machine with a main generator and an exciter generator. The main generator and the exciter generator may each have stator windings and rotor windings. A shorting switch may be provided for interconnecting the stator windings of the exciter generator together when power is applied to stator windings of the main generator. This may result in starting torque being produced by the exciter generator, which starting torque may be additive to starting torque produced by the main generator.

    Abstract: A multi-sage controlled frequency generator is described that has a low size, weight and cost. The new generator requires an electronic controller that requires only 25% of the total generated power (100%) when the generator shaft speed varies by +/−25% around its synchronous speed. The shaft driving the generator in the direct-drive controlled frequency generator may be moved at a variable speed. The output frequency of the generator may be controlled by electrically controlling the frequency of the first stator stage and by selecting the control frequency, the number of poles, and the number of stages, such that the output of the last stage will be maintained constant at the desired grid frequency.

    Abstract: A method and a system of setting up a reference signal in a radio communication system. The radio communication system includes a serving cell and a neighboring cell, and a mobile terminal of the serving cell uses the same temporal frequency resource so as to receive a serving resource block from the serving cell and receive an interference resource block from the neighboring cell. The method according to the present disclosure includes a step of setting up a user-specific reference signal in the interference resource block and a step in which puncturing is performed at same temporal frequency position as the temporal frequency position at which the user-specific reference signal is set up on the interference resource block of the serving resource block so as to prevent any signal from being transmitted at the punctured temporal frequency position. When the method and the system provided in the present disclosure are used and the interference power between cells is thereby measured, it is possible to effectively reduce feedback overhead in a coordinated beamforming.
