摘要： A method for controlling operation of an electric power generation system includes receiving power generator data corresponding to the electric power generation system. The method further includes receiving, using a digital prime mover unit, a set-point parameter corresponding to a prime mover unit and generating one or more prime mover parameter estimates corresponding to the plurality of prime mover parameters. Further, the method includes receiving, using a digital generator unit, one or more prime mover parameter estimates and generating one or more generator parameter estimates corresponding to the plurality of generator parameters. The digital prime mover unit and the digital generator unit are real-time operational models of the prime mover unit and the generator unit.

摘要： The present disclosure relates to gas turbine engine operation in which an igniter assembly is provided with an electrical energy input (e.g., an electrical waveform) that is configured to increase a likelihood of igniting a fuel-air mixture surrounding the igniter assembly. In certain embodiments, the igniter assembly is supplied with an augmented electrical waveform that may reduce a quantity of sparks generated by the igniter assembly before successful light-off (e.g., ignition) of the fuel-air mixture is achieved (e.g., as compared to a quantity of sparks generated to achieve ignition by an igniter assembly that receives an electrical energy input in the form of a conventional electrical waveform). Accordingly, the augmented electrical waveform may reduce wear (e.g., via oxidation) on electrodes of the igniter assembly, such as a primary electrode (e.g., a center electrode) and a secondary electrode (e.g., an outer shell electrode) disposed about the primary electrode.

摘要： Systems and methods are disclosed for on-line monitoring of the condition of the stator insulation of an AC motor or an electric generator. In certain embodiments, the system includes a transformer surrounding each pair of input and output cables associated with a given phase of power provided to the AC motor or generated by the electric generator. In another embodiment, a transformer surrounds the three input cables (for an AC motor) or the three output cables (for an electric generator) that correspond to phases of the AC motor or electric generator. In both embodiments, the transformers generate voltages that may be used to monitor leakage currents associated with the cables. A microcontroller monitors the voltages generated by the transformers and determines the condition of the stator insulation of the AC motor or the electric generator based on the voltages.

摘要： Methods and systems detect short circuits in an electrical system, such as a dynamic braking grid of a vehicle. The methods and system measure a characteristic of a current that is conducted through one or more resistive elements of an electrical system. The current is supplied to the electrical system from a power source as an applied voltage. A resistance change signal representative of a change in one or more electrical resistances of the one or more resistive elements is determined The resistance change signal can be based at least in part on a difference between the characteristic of the current that is measured and a low pass filtered value of one or more of the characteristic of the current that is measured or the applied voltage supplied by the power source. A short circuit event is identified based at least in part on the resistance change signal.
