中国启动全球最大浮动太阳能电厂 满足万户家庭用电

2017-08-15 01:07:27   参考消息

参考消息网8月15日报道 德媒称,中国太阳能发电站之多是世界任何国家都无法比及的。在中国东部的淮南市,一座特殊的太阳能发电站现在投入使用。几年前只有几位农民在此靠打鱼、养鸭为生的一个湖泊上,如今建起了一座有16万块电池板,总装机容量40MW的全球最大浮动太阳能发电厂。

据德国之声电台网站8月13日报道,要想参观中国安徽省的这个新建的太阳能样板发电站,首先要登上一条船。数分钟后,船只从无数个漂浮在湖面的太阳能电池板旁驶过。这些电池板都被固定在灰色的扁平塑料箱上。在淮南参加了这一巨型浮动太阳能发电站建设的江凡(音译)说:“从前这里是一个煤矿塌陷的地方,后来形成了一个巨大的湖泊。”

负责浮动太阳能电站的设计和施工的JA Solar中国公司表示,建造这个浮动太阳能发电站是为了向人们展示,太阳能光板除了可以发电之外还有很多其他功能。例如这个项目就有助于保护水源和生态景观。该公司欧洲部经理舒尔茨表示:“最值得注意的总共有两点。一是不能大面积的密封,二是湖泊和水库的水蒸发明显减少。”

报道称,建造水上浮动太阳能发电站的好处不仅仅在于无须占用昂贵的土地,而且可以多发电。原因之一是太阳能光板下的水冷却提高了发电的效率。

第二个原因是“与陆地相比水面灰尘少。位于水面的太阳能电池板几乎没有灰尘,因此发电效率高,比陆地上发电多。”

当然也有不足之处:与类似的陆地发电站相比,水上浮动发电站的建造和运营成本要高。为了避免水的腐蚀,电池板和电缆都必须加强防水功能。此外每天要派工人到湖面巡视,清除电池板下的水藻,有时多达12人。江凡说:“如果不及时清除这些水藻,可能会造成巨大损失。只要有空隙,就会长出海藻。它会威胁设备的正常运转。所以只要我们发现有海藻,就必须清除。”

报道称,16万块电池板和40MW的装机容量使其成为全球最大的一个水上浮动太阳能发电站。所生产的电能可以满足1.5万户家庭的用电需求。Ja Solar太阳能公司的舒尔茨认为这个项目不仅仅是一个样板工程。他表示:“由于中国对电力的需求,很多项目自动成为世界最大。在这里我想说的是,这个项目并非简单的只是作为一个景观,只为了告诉人们这是世界最大的浮动太阳能发电站,而是确实出于对电的需求。”

与此同时,浮动电站也象征着这个中国安徽省昔日产煤区的结构发生变化。项目经理江凡表示,虽然这里还有烟囱吐着白烟的巨大燃煤发电站,但已不再是唯一。江凡说:“5年前只有几位农民在这里靠打鱼和养鸭为生。由于这里阳光充足,所以我们让这个从前长久冷清的地区重新热闹起来。”
