摘要： A medium voltage inrush current (MVIC) regulator and interconnection control system for interposing between a distributed power generation facility and a utility grid. The facility has a designated generator step-up (GSU) transformer and is connected to the utility grid at a point of interconnect. The system includes a pre-insertion impedance injection transformer, a low voltage first switch connected between the pre-insertion transformer and secondary coils of the designated GSU transformer, a medium voltage second switch connected inline between the pre-insertion transformer and primary coils of the designated GSU transformer, and a controller. In response to restoration of the utility grid following a loss-of-grid event, the controller opens and closes the first and second switches according to an automated pre-energization switching sequence such that magnetic flux in the designated GSU transformer occurs at a reduced rate, thereby reducing inrush of current and undesirable power quality phenomena

摘要： A significantly self-contained station for providing selective control and operation of motorized equipment (such as a conveyor) via a momentary contact switch or wireless remote, where the self-contained station is connected to and receives power from an existing service disconnect line of the equipment, where upon the service disconnect line being powered, the self-contained station receives power to provide electrical signals to a motor contactor of the self-contained station, which then selectively provides electrical signal to a motor of the equipment to selectively operate the equipment.

摘要： An idling-stop control apparatus includes an idling-stop controller and an auxiliary-machine controller. The idling-stop controller is configured to automatically stop an engine to cause the engine to be in a state in which idling is stopped in a case where a predetermined condition for stopping idling is satisfied and configured to automatically restart the engine in a case where a predetermined condition for restarting the engine is satisfied. The auxiliary-machine controller is configured to control a drive state of an auxiliary machine that is to be driven by the engine. The auxiliary-machine controller is configured to control the drive state of the auxiliary machine that is driven by the engine such that, in a case where the engine is automatically restarted from the state in which idling is stopped by the idling-stop controller, a time differential value of an engine speed of the engine is constant.

摘要： An electrical generator is provided. The electrical generator can include a generator, an electric motor, and a battery. The generator has a rotatable shaft and stationary component and be operatively coupled via a drive belt to the motor, which provides torque to the rotatable shaft of the generator The battery is operatively coupled to the motor. The generator can be operatively coupled to a utility grid via a transformer/invertor that can import current from the utility grid to charge the battery when the utility grid is operating and export current from the generator to a grid connector when the utility grid is not operating.

摘要： A generator includes: an engine; an alternator attached to an output shaft of the engine; an inverter that rectifies current flowing between the alternator and a power receptacle (power input-output part) in both directions and performs power conversion; an ECU that supplied electric power to the inverter and controls the engine and the inverter; and a starting unit that supplies, to the ECU, electric power from an external power supply device to be connected to the power receptacle, and the alternator is energized to start the engine, by sending a starting initiation instruction from the ECU to the inverter.

摘要： A brushless starter-generator system is contained within a single housing. The housing has a first end with an opening to receive a drive spline from a motive source and an opposing second end. A brushless, rotating machine is located adjacent the first end and is kinetically connectable to the drive spline. A power control unit is adjacent the second end and electrically coupled to the brushless, rotating machine. The brushless, rotating machine is selected from the group consisting of a synchronous machine, a permanent magnet machine, and an induction machine. Electrical and mechanical interfaces are identical to a like-rated brushed version for a true “drop-in” replacement capability to facilitate replacements and up-grades.

摘要： Systems and methods are provided for braking a translator of a linear multiphase electromagnetic machine. The system detects a fault event, and in response to detecting the fault event, causes the translator to brake using an electromagnetic technique. Braking includes causing the translator to stop reciprocating, by applying a force opposing an axial motion, which may occur within one cycle, or over many cycles. The fault event may include, for example, a fault associated with an encoder, a controller, an electrical component, a communications link, a phase, or a subsystem. The system includes a power electronics system configured to apply current to the phases. The system may use position information, current information, operating parameters, or a combination thereof to brake. Alternatively, the system need not use position information, current information, and operating parameters, and may brake the translator independent of such information.

摘要： A method of controlling a power system that includes an electrical machine, e.g., wind turbine generator, a power converter, a DC circuit and a dynamic braking system (DBS) having a braking circuit having a braking resistor and being connected in series to the DC circuit, is provided. The method includes operating the DBS and controlling operation of the electrical machine based on a prevailing temperature of the braking circuit, stopping the electrical machine and controlling the electrical machine to be restarted at its rated output power once the prevailing temperature of the braking resistor reaches or falls below a lower temperature threshold. The electrical machine may be restarted at a lower output power and after restarting, its output power can be increased based on a power starting profile as the braking resistor cools.

摘要： In an embodiment a method includes: sensing a first signal indicative of magnetization of a winding in a dynamoelectric machine; applying the first signal to a window comparator having a comparator window between upper and lower thresholds and generating window exit signals indicative of the first signal exiting the comparator window of the window comparator; generating a slowed-down replica signal of the first signal; updating the comparator window of the window comparator as a function of the slowed-down replica signal; and issuing a wake-up signal towards a control device of the dynamoelectric machine as a result of one of the window exit signals indicating the first signal exiting the comparator window of the window comparator for a time duration in excess of a duration threshold.

摘要： A drive train for a motor vehicle includes an internal combustion engine, a starting device, and a vibration isolation device. The internal combustion engine has a main order of vibration and an excitation frequency predetermined by a predetermined operating principle and a predetermined number of cylinders. The starting device is for starting the internal combustion engine and has an electric machine with a torque characteristic over a speed (n). The vibration isolation device is designed for the main order of vibration of the internal combustion engine. The vibration isolation device has a resonance characteristic below an idling speed (nL) of the internal combustion engine in a resonance range occurring in a first speed range (Δn2). The resonance range is shifted into a second, lower speed range (Δn1) when the electric machine is coupled. The electric machine is arranged to supply a torque effective beyond the second, lower speed range (Δn1).
