Power generating device with voltage rises temporarily and falls function temporarily

The utility model discloses a power generating device with voltage rises temporarily and falls function temporarily. At present based on VSG control advanced person, the flexibility of dc -to -ac converter, can simulate multiple voltage trouble, but be seen in the report only realize falling temporarily of voltage. The utility model discloses a step up transformer, rectifier unit, inverter unit, the sinusoidal wave wave filter of LC, IGBT drive and protection circuit, sampling circuit and the control unit, inverter unit be three -phase PWM dc -to -ac converter, rectifier unit do not control the rectifier bridge for the three -phase. The utility model has the advantages of can adjust in a flexible way, export the accuracy and dynamic response is fast, the grid voltage that can simulate the IEEEll59 -1995 standard code rises / falls temporarily the phenomenon temporarily, can satisfy the high low voltage ride through supporting arrangement's of converter test requirement, also can be used for other electric and capability test and the research of electronic product under the grid voltage abnormal conditions.
