Hydropower Knowledge

Reaction turbine can be divided into Francis turbine, axial turbine, diagonal turbine and tubular turbine. In the Francis turbine, the water flows radially into the water guide mechanism and axially out of the runner; In the axial flow turbine, the water flows into the guide vane radially and int...Read more »

Hydropower is a process of converting natural water energy into electric energy by using engineering measures. It is the basic way of water energy utilization. The utility model has the advantages of no fuel consumption and no environmental pollution, water energy can be continuously supplemented...Read more »

Pumped storage hydropower station is the most widely used and mature technology in large-scale energy storage, and the installed capacity of the power station can reach gigawatt level. At present, the pumped storage power station with the most mature development scale in the world. Pumped storag...Read more »

There are many kinds of hydro generators. Today, let’s introduce the axial-flow hydro generator in detail. The application of axial-flow hydro generator in recent years is mainly the development of high water head and large size. The development of domestic axial-flow turbines is also fast....Read more »

The speed of water turbines is relatively low, especially the vertical water turbine. In order to generate 50Hz AC, the water turbine generator adopts multi pair magnetic pole structure. For the water turbine generator with 120 revolutions per minute, 25 pairs of magnetic poles are required. Beca...Read more »

It has been 111 years since China started the construction of shilongba hydropower station, the first hydropower station in 1910. In these more than 100 years, from the installed capacity of shilongba hydropower station of only 480 kW to the 370 million KW now ranking first in the world, China...Read more »

Water turbine is a kind of turbine machinery in fluid machinery. As early as about 100 BC, the prototype of water turbine – water turbine has been born. At that time, the main function was to drive machinery for grain processing and irrigation. Water turbine, as a mechanical device powered ...Read more »

Pelton turbine (also translated: Pelton waterwheel or Bourdain turbine, English: Pelton wheel or Pelton Turbine) is a kind of impact turbine, which was developed by American inventor Lester W. Developed by Alan Pelton. Pelton turbines use water to flow and hit the waterwheel to obtain energy, whi...Read more »

The rotational speed of hydraulic turbines is relatively low, especially for vertical hydraulic turbines. In order to generate 50Hz alternating current, the hydraulic turbine generator adopts a structure of multiple pairs of magnetic poles. For a hydraulic turbine generator with 120 revolutions p...Read more »

The water turbine is a turbomachinery in the fluid machinery. As early as around 100 BC, the prototype of the water turbine, the water wheel, was born. At that time, the main function was to drive machinery for grain processing and irrigation. The water wheel, as a mechanical device that uses wat...Read more »

Hydro generator is composed of rotor, stator, frame, thrust bearing, guide bearing, cooler, brake and other main components (see Figure). The stator is mainly composed of frame, iron core, winding and other components. The stator core is made of cold-rolled silicon steel sheets, which can be made...Read more »

1. The load shedding and load shedding tests of hydro generator units shall be conducted alternately. After the unit is initially loaded, the operation of the unit and relevant electromechanical equipment shall be checked. If there is no abnormality, the load rejection test can be carried out acc...Read more »
