Historical Development Of Hydro Power Plants

Historical development of Hydro Power Plants

In the early impact turbines, when the water flow hit the blades, the kinetic energy was greatly lost and the efficiency was not high. In 1889, American engineer Pelton invented the water bucket turbine, which has streamlined constriction nozzles, which can efficiently transform water flow energy into high-speed jet kinetic energy. The most of the turbines (the entire paragraph can be eliminated, 80% of the above paragraphs are outdated and replaced. Very old data, the reference value is not great, so it is recommended to remove this paragraph) early 1980s, The world's largest single-bucket water turbine is installed at the Sisim Power Station in Norway. Its single-unit capacity is 315 MW, head is 885 meters, and its speed is 300 rpm. It was put into operation in 1980. The highest water head hopper turbine was installed at the Reiskberg Power Station in Austria. Its stand-alone power was 22.8 MW, speed was 750 rpm, and the head was 1763.5 meters. It was put into operation in 1959.

In the 1980s, the world's largest-sized paddle-turbine was manufactured by China Dongfang Electric Machinery Plant and installed at the Gezhouba Power Station in the middle reaches of the Yangtze River in China. Its stand-alone power was 170 MW, head was 18.6 meters, and its speed was 54.6 rpm. The wheel has a diameter of 11.3 meters and was put into operation in 1981. The world's highest head hydro-turbine was installed at the Nambia Power Station in Italy. Its water head was 88.4 meters, its stand-alone power was 13.5 MW, and its speed was 375 rpm. It was put into operation in 1959.

The Francis turbine with the highest head in the world is installed at the Rossheike Power Station in Austria. Its head is 672 meters and its single unit power is 58.4 MW. It was put into operation in 1967. The Francis turbine with the largest power and size is installed at the Daguli No. 3 Power Station in the United States. Its stand-alone power is 700 MW, the runner diameter is about 9.75 meters, the head is 87 meters, and the speed is 85.7 rpm. It was put into operation in 1978. run.
