  • Effect of adding fins to the wall of draft tube on pressure pulsation of Francis turbine
    Post time: Aug-09-2022

    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 »

  • Analyze The Advantages And Disadvantages Of Hydropower
    Post time: Aug-04-2022

    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 »

  • Introduction And Main Application Scenarios of Pelton Turbine Generator
    Post time: Jul-28-2022

    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 »

  • Construction and labor costs of hydroelectric power plants
    Post time: Jul-22-2022

    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 »

  • How Hydropower Plants and Hydro Turbine Generator Work
    Post time: Jul-21-2022

    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 »

  • Norway, where hydropower accounts for 90%, has been hit hard by drought
    Post time: Jul-19-2022

    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 »

  • How to Optimize a Francis Turbine Generator
    Post time: Jul-15-2022

    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 »

  • Why hydropower is the forgotten giant of clean energy
    Post time: Jul-14-2022

    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、 Items to be checked before startup: 1. Check whether the inlet gate valve is fully open; 2. Check whether all cooling water is fully opened; 3. Check whether the bearing lubricating oil level is normal;Shall be located; 4. Check whether the instrument network voltage and frequency paramet...Read more »

  • Where does the power of the hydro-generator rotor come from?
    Post time: Jun-09-2022

    Both hydropower and thermal power must have an exciter. The exciter is generally connected to the same large shaft as the generator. When the large shaft rotates under the drive of the prime mover, it simultaneously drives the generator and the exciter to rotate. The exciter is a DC generator tha...Read more »
