摘要： PURPOSE:To enable to establish the voltage of an induction generator stably by operating an AC/DC converter in bypass pair at the initial stage of establishment of the voltage, operating a separately-excited inverter with a rectifier, and storing energy in a DC reactor. CONSTITUTION:When the voltage of an induction generator IG is established, upper and lower arms of AC/DC converter 1 for one phase are simultaneously energized, the phase angle of a separately-excited inverter 2 is controlled to operate a rectifier, and energy is stored in a DC reactor 3. When this energy and hence the current of the DC link circuit reaches the sufficient value of exciting the generator, the converter 1 is returned to the normal operation to establish the voltage. In this manner, the voltage of the generator can be stably established without installing a new device.

摘要： PURPOSE:To establish smoothly and stably the voltage of an induction generator by setting the forcible commutation type rectifying circuit in OFF state prior to the excitation of the generator and flowing a current from an auxiliary DC power source to a reactive leading power supply DC reactor. CONSTITUTION:When the voltage of an induction generator IG is established, a rectifying circuit RF is initially set in the stopping state, and a current is supplied from an auxiliary DC power source AC through a rectifier AR1 to a DC reactor DL. When the current value reaches the prescribed value, the rectifier AR1 is interrupted OFF, and the rectifying circuit RF is simultaneously started. Thus, the current of the DC reactor DL flows into the induction motor IG, and the terminal voltage starts rising. The magnitude of the terminal voltage is controlled by the phase control of the rectifying circuit RF. In this manner, the voltage of the induction generator can be smoothly and stably established.

摘要： A system and method is provided for generating DC power using a synchronous reluctance machine (12) or a salient-pole synchronous machine (102) and a power converter (110). The present invention can be used to achieve power production for a synchronous reluctance machine (12), or can be used to achieve partial production of power from a traditional salient-pole synchronous machine/starter (102) in the case where the salient-pole synchronous machine/starter has degenerated into a synchronous reluctance machine due to, for example, a loss of excitation. In a power generation system, a control system and method can include a power converter (110), controlled by a voltage command and at least one of a measured DC link (120) voltage or DC link (120) current, for use with a synchronous reluctance machine armature winding (102A) and a prime mover (116), such that movement of the synchronous reluctance machine rotor of the synchronous reluctance machine can be used to produce at least partial DC power generation.
