标题(英语)

Apparatus for implementing low voltage cross-over of wind generator set


摘要(英语)

A device for realizing the low voltage crossing of the wind generating set includes an energy storage device reactance transformer, an energy conversion device AC and DC convertor and protective devices thereof, and a bypass switch controlled by the fan main control system, wherein the primary edge of the reactance transformer is respectively electrically connected with a filter and a net side transformer, and the assistant edge is connected with the bypass switch, the AC and DC convertor and the protective devices in parallel. The voltage output end of the AC and DC convertor is connected with the DC voltage input end of the uninterruptable power supply. When the mains voltage falls, the bypass switch is broken, the energy stored in the reactance transformer is provided to the uninterruptable power supply through the AC transformer, to ensure that the uninterruptable power supply has ample electric energy to supply to key parts of all the subsystems, and realize the low voltage crossing, meanwhile, since the assistant edge of the reactance transformer provides power to the AC and DC convertor, the equivalent impedance is greatly advanced and the current is effectively restrained.
