    摘要: A controlled frequency generating system (CFG) may be constructed with a main generator and an exciter driven by a common shaft. Excitation power may be provided from the common shaft; as distinct from prior-art systems which may require independent excitation power sources. While controlling the output voltage and frequency of the main generator, the bi-directional controller extracts power from a main generator output and may supply the extracted power to supplement excitation power when needed at certain rotational speeds. The controller may extract power from the exciter when, at other rotational speeds, the exciter produces excess power. The extracted excess power may be delivered to the output of the main generator to maintain a desired level of output power at a desired frequency, irrespective of speed of rotation of the CFG.

    摘要: A power system for a vehicle may comprise an electric machine attached to an engine of the vehicle. The electric machine may comprise only one stator core; a stator main winding wound on the one stator core; a stator exciter winding wound on the one stator core. The stator main winding and the stator exciter winding may be magnetically independent from one another even though magnetic-field-isolation material is not interposed between the stator main winding and the stator exciter winding.

    摘要: 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.

    摘要: Systems, methods, and apparatuses for pressure recovery and power generation may include a pressure recovery generator configured to receive a high-pressure fluid and generate current based on expansion of the high-pressure fluid. The current may be directed to a power electronics module that is configured to receive current from the pressure recovery generator and provide current to a closed-loop thermal cycle, such as an ORC. The current can be used to start components of the closed-loop thermal cycle, such as the pump and/or to black start the turbine generator. In some instances, the current can be combined with current generated by the closed-loop thermal cycle and directed to a utility grid or to external loads. The high-pressure fluid may be directed to heat exchanger components of the closed-loop cycle. For example, high-pressure, high-temperature fluid can be directed to an evaporator, while high-pressure, low-temperature fluid can be directed to a condenser.
