LOW VOLTAGE RIDE-THROUGH APPARATUS CAPABLE OF FLUX COMPENSATION AND PEAK CURRENT MANAGEMENT |
摘要 |
A low voltage ride-through (LVRT) apparatus capable of flux compensation and peak current management is disclosed, which comprises a converter; a space vector modulator, connected to the converter; a current controller, connected to the space vector modulator; an grid realization system, connected to the current controller; a flux offset compensator, connected to the current controller; a filter, connected to the converter; and a transformer, connected to the filter. In this manner, the LVRT apparatus may be connected to an associated grid side (commercial power), and thus applied onto a direct current (DC) to alternating current (AC) system for renewable energy source. When the grid side is failed, a flux offset on a transformer may be eliminated, to avoid an inrush current from rising after a recovery of failure exclude voltage, so that the requirement of the grid operation may be satisfied. |
