摘要： A method of compensating for rotor position error of a rotor of a permanent magnet synchronous generator (PMG) that provides electrical power to a direct current (DC) power generating system, the method including obtaining PMG phase voltages and resolver processed angular position output when the PMG is driven by a prime mover. Once obtained, a PMG fundamental phase voltage waveform is selected by eliminating higher order harmonics. A mechanical angle of the rotor is then converted into an electrical angle, then the electrical angle is aligned within the mechanical angle with a corresponding PMG fundamental phase voltage angle by adjusting offset to the electrical angle. After alignment, a plurality of resolver error offset values associated with the electrical angle are stored and additional values to the compensation table are added by interpolating data between two corresponding resolver error offset values of the plurality of resolver error offset values.

摘要： Systems and methods for pre-aligning rotors of synchronous motors on a synchronous AC grid prior to startup of the motors are provided. A partial power converter may provide an alignment current through an n-phase supply line to a synchronous AC motor. The synchronous AC motor may be configured to receive polyphase AC power through the n-phase supply line from the synchronous AC grid, whereas the partial power converter is powered by a power source isolated from the synchronous AC grid. The alignment current may cause a rotor of the synchronous AC motor to move to and stop at a target angular position.

摘要： A system for connecting a single-phase generator in parallel with an inverter is disclosed. A signal corresponding to the angular position of the rotor in the generator is provided to the inverter, for example, from an angular position sensor connected to the rotor in the generator. Because variations in the load applied to the generator cause variations in the frequency of the power output by the generator, the inverter synchronizes the phase angle of the voltage output by the inverter to the angular position of the rotor.

The frequency control unit controls a frequency of a sensor signal synchronous with an operation of the power generator, and the cycle obtaining unit obtains a cycle of the sensor signal whose frequency is controlled by the frequency control unit. The determination unit determines the phase sequence of the power generator by detecting timing at which an output voltage outputted from each of the phases of the power generator has risen using the cycle of the sensor signal obtained by the cycle obtaining unit. The output-supply control unit controls a drive circuit according to the phase sequence of the power generator determined by the determination unit.

摘要： A control method for a switched reluctance generator employing dual switched-mode power converters does not require a position sensor. In the excitation stage, the upper tube and lower tube of the main switch of a phase in the power converter are switched on, and the phase current is detected. When the phase current rises to a preset threshold, the upper tube or lower tube of the main switch of the phase is switched off, changing the phase of the switched reluctance generator into a zero voltage natural freewheeling state. When the phase current drops to the valley value, the rotor position is the end position of maximum phase inductance of the phase. This rotor position is used as the switch-off position of the main switch of the phase of the switched reluctance generator, and the upper tube and lower tube for the main switch of the phase are switched off.

摘要： In a synchronous machine starting device, an AC voltage detection unit detects AC voltage supplied to an armature of a synchronous machine through an electric power line from a power conversion unit. The AC voltage detection unit has a first output end and a second output end isolated from the electric power line, transforms AC voltage supplied through the electric power line at a first ratio to output the transformed voltage from the first output end, and transforms AC voltage supplied through the electric power line at a second ratio and then limits the transformed voltage to a prescribed positive voltage value or lower and a prescribed negative voltage value or higher for output from the second output end. Then, a detected voltage selection unit selects one of the voltage received from the first output end and the voltage received from the second output end, and outputs the selected one to a rotor position detection unit. The rotor position detection unit detects a rotor position of the synchronous machine based on the voltage received from the detected voltage selection unit. A power conversion control unit controls the power conversion unit based on the detected rotor position.

摘要： A hydraulic system includes a variable displacement hydraulic pump connectable to a power source, a hydraulic motor, a fluid circuit, a pump displacement control, and a controller. The pump has an inlet for receiving fluid, an outlet for discharging pressurized fluid, and a pump displacement input. The motor has an inlet for receiving pressurized fluid and an outlet for discharging spent fluid. The fluid circuit includes a supply conduit for conducting fluid discharged by the pump to the motor and a return conduit for returning fluid discharged by the motor to the pump. The pump displacement control cooperates with the pump displacement input to vary pump displacement. The controller communicates with the pump displacement control to control the pump output such that the motor is driven at a constant speed to thereby drive a generator connected to the motor at a constant speed despite speed fluctuations of the power source.
