世界最大的潮汐发电站是法国朗斯水电站(La Rance),位于法国朗斯河口圣·马洛城附近。该处最大潮高13.5米,最大潮流量18,000立方米/秒。拦潮坝长750米,电厂长386米,安装有24台单机1万千瓦容量的贯流式水轮机组,总装机容量24万千瓦。第一台机组于1966年11月投产,1968年1月全部完成。为了抵御海水腐蚀,机组叶片有一半采用不锈钢材料制造,另有一半采用铝质青铜制造,并喷涂特殊涂料,
The world’s largest tidal power station is the French Rance hydroelectric power plant (La Rance), located near the mouth of Saint-Malo in France’s Ries estuary. The maximum tide height of 13.5 meters here, the maximum flow of 18,000 cubic meters / second. Barrage barrage 750 meters long, power plant 386 meters long, installed 24 stand-alone 10,000 kilowatts of capacity tubular turbine with a total installed capacity of 240,000 kilowatts. The first unit was put into operation in November 1966 and was completed in January 1968. In order to resist seawater corrosion, half of the blades of the unit are made of stainless steel, the other half are made of aluminum bronze and sprayed with special paint,
