風力發電是技術較成熟、*商業潛力的新能源之一。無錫風力風機制造有限公司目前，我國已進入大規模開發利用階段，在2010年底超過美國，成為世界*大風電裝機大國。但我國的風電機組技術水平較差，國內風電機組約80%的風力發電機組，存在著無法實現低電壓穿越、難以滿足電網并網要求的問題。低電壓穿越和零電壓穿越是風電設備的核心技術，是決定風電機組能否安全并網的關鍵指標。低電壓穿越，如同在電網這條高速公路上，行駛中的風電遇到公路流量大幅波動或路障時，不是選擇迅速靠邊停車、引起交通混亂，而是開辟一個窄的通道，以保障公路有效通行。（圖/文http://www.alsdl.com/）

Wind power is a more mature technology, most of the commercial potential of new energy sources. At present, China has entered a stage of large-scale exploitation, at the end of 2010 more than the United States, to become the world's first wind power installed power. But in our country, the technology of wind turbine was poor, the domestic wind turbines approximately 80% of the wind turbine, there are unable to realize the low voltage ride-through, difficult to meet the requirements of the grid. Low voltage ride-through and zero voltage crossing is the core technology of wind power equipment, is to determine the wind turbine can be safely combined key indicators. Low voltage ride-through, as in the power grid this freeway, running in the wind flow fluctuations or encounter highway barricade, chose not to pull over quickly, caused traffic chaos, but open up a narrow channel, in order to ensure the effective traffic highway.
