1整体情况近些年来,中国风电机组的单机容量逐渐向更大发展。根据中国可再生能源学会风能专业委员会(CWEA)的统计显示,单机容量为3MW(及以上)的多兆瓦级风电机组自2009年安装第一台,在当年便有了批量生产和安装。但在2009年至2010年的两年间,此类多兆瓦级机组的装机量维持在双位数,没有明显的增量。2011年此类机型的新增装机量比2010年上升了606%,虽然2012年略有下降,但2013年又有微幅的上升。2013年3MW(及以上)机型新增装机容量为422MW,截至2013年底3MW(及以上)机型的累计装机量为
1 Overall Situation In recent years, the stand-alone capacity of wind turbines in China has gradually increased. According to CWEA’s statistics, the multi-megawatt wind turbine with unit capacity of 3MW (and above) installed the first one in 2009 and was mass-produced and installed in that year. However, for the two years from 2009 to 2010, the installed capacity of these multi-megawatt units remained at double digits with no significant increase. In 2011, the installed capacity of such aircraft increased by 606% compared with that of 2010, and although a slight decrease in 2012, there was a slight increase in 2013. The new installed capacity of 3MW (and above) models in 2013 was 422MW. As of the end of 2013, the accumulated installed capacity of 3MW (and above) models was
