世界上效益最大的水利枢纽 l、防洪效益大。三峡水库运行时预留的防洪库容为221.5亿立方米,水库调洪可削减的洪峰流量达27000—33000立方米/秒,属世界水利工程之最。 2、水电站大。三峡水电站将安装26台单机容量为70万千瓦的水轮发电机组,总装机容量1820万千瓦,年平均发电量846.8亿度,将是世界上最大的水电站。 3、航运效益显著。三峡水库回水至西南重镇重庆市,它将改善肮运里程660公里,使重庆至宜昌航道通行的船队吨位由现在的3000吨级提高至万吨级,年单向通航能力由1000万吨提高到5000万吨。称三峡工程为世界上改善航
The world’s most effective water conservancy hub l. Large flood control benefits. When the Three Gorges Reservoir is in operation, it reserves a total of 22.15 billion cubic meters of flood protection capacity, and the flood peak discharge capacity of the reservoir can be reduced by 27,000-33,000 cubic meters per second, which is the highest in the world’s water conservancy projects. 2. The hydropower station is large. The Three Gorges Hydropower Station will install 26 turbine generating units with a capacity of 700,000 kilowatts each, with a total installed capacity of 18.2 million kilowatts and an annual average power generation of 84.68 billion kwh, which will be the world’s largest hydropower station. 3, significant shipping benefits. The Three Gorges Reservoir will return to Chongqing, a town in southwest China. It will improve the mileage of 346 kilometers, increase the tonnage of the fleet from Chongqing to Yichang Channel from the current 3,000 tons to 10,000 tons, and increase the one-way navigation capacity by 10 million tons. Increased to 50 million tons. Says the Three Gorges project as the world’s improved aviation
