Hydropower Knowledge

Recently, Sichuan Province issued the document “emergency notice on expanding the scope of power supply for industrial enterprises and the people”, requiring all power users to stop production for 6 days in the orderly power consumption scheme. As a result, a large number of listed co...Read more »

In recent years, the pace of hydropower development has made steady progress and the toughness of development has increased. Hydropower generation does not consume mineral energy. The development of hydropower is conducive to reducing greenhouse gas emissions and protecting the ecological environ...Read more »

On March 3, 2022, there was a power outage without warning in Taiwan Province. The outage affected a wide range, directly causing 5.49 million households to lose power and 1.34 million households to lose water. In addition to affecting the lives of ordinary people, public facilities and factories...Read more »

As a fast-response renewable energy source, hydropower usually plays the role of peak regulation and frequency regulation in the power grid, which means that hydropower units often need to operate under conditions that deviate from the design conditions. By analyzing a large number of test data, ...Read more »

Using the gravity of flowing water to generate electricity is called hydropower. The gravity of water is used to spin turbines, which turn magnets in rotating generators to generate electricity, and water energy is also classified as a renewable energy source. It is one of the oldest, cheapest an...Read more »

We have previously introduced that the hydraulic turbine is divided into an impact turbine and an impact turbine. The classification and applicable head heights of impact turbines were also introduced before. Impact turbines can be divided into: bucket turbines, oblique impact turbines and double...Read more »

POWER PLANT TYPE VS. COST One of the core factors affecting construction costs for power generation facilities is the type of proposed facility. Construction costs can vary widely depending on whether they are coal-fired power plants or plants powered by natural gas, solar, wind, or nuclear gene...Read more »

Worldwide, hydropower plants produce about 24 percent of the world’s electricity and supply more than 1 billion people with power. The world’s hydropower plants output a combined total of 675,000 megawatts, the energy equivalent of 3.6 billion barrels of oil, according to the National...Read more »

While Europe scrambles to procure natural gas for winter power generation and heating, Norway, the largest oil and gas producer in Western Europe, faced an entirely different power problem this summer — dry weather that depleted hydroelectric reservoirs, which Electricity generation accounts for ...Read more »

A water turbine, with the Kaplan, Pelton, and Francis turbines being the most common ones, is a large rotary machine that works to convert kinetic and potential energy into hydroelectricity. These modern equivalents of the water wheel have been used for over 135 years for industrial power generat...Read more »

Hydropower is by far the largest renewable worldwide, producing over twice as much energy as wind, and over four times as much as solar. And pumping water up a hill, aka “pumped storage hydropower”, comprises well over 90% of the world’s total energy storage capacity. But in spite of hydropower’...Read more »

1、 The output of wheel generator decreases （1） Cause Under the condition of constant water head, when the guide vane opening has reached the no-load opening, but the turbine has not reached the rated speed, or when the guide vane opening is increased than the original at the same output, it ...Read more »
