Recently, Forster successfully helped South African customers upgrade the installed power of his 100kW hydropower station to 200kW. The upgrade scheme is as follows 200KW kaplan turbine generator Rated head 8.15 m Design flow 3.6m3/s Maximum flow 8.0m3/s Minimum flow 3.0m3/s Rated installed capac...Read more »

1. Causes of cavitation in turbines The reasons for the cavitation of the turbine are complex. The pressure distribution in the turbine runner is uneven. For example, if the runner is installed too high relative to the downstream water level, when the high-speed water flows through the low-press...Read more »

Pumped storage is the most widely used and mature technology in large-scale energy storage, and the installed capacity of power stations can reach gigawatts. At present, the most mature and largest installed energy storage in the world is pumped hydro. Pumped storage technology is mature and sta...Read more »

In addition to the working parameters, structure and types of hydraulic turbine introduced in previous articles, in this article, we will introduce the performance indexes and characteristics of hydraulic turbine. When selecting a hydraulic turbine, it is important to understand the performance o...Read more »

Prevent phase-to-phase short circuit caused by loose ends of stator windings The stator winding should be fastened in the slot, and the slot potential test should meet the requirements. Regularly check whether the stator winding ends are sinking, loose or worn. Prevent stator winding insulatio...Read more »

There is no direct relationship between the AC frequency and the engine speed of the hydropower station, but there is an indirect relationship. No matter what type of power generation equipment it is, it needs to transmit power to the grid after generating electricity, that is, the generator need...Read more »

1. What is the basic function of the governor? The basic functions of the governor are: (1) It can automatically adjust the speed of water turbine generator set to keep it running within the allowable deviation of rated speed, so as to meet the requirements of power grid for frequency quality ...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 Argentina customer 2x1mw Francis turbine generators have completed production testing and packaging, and will deliver the goods in the near future. These turbines are the fifth hydroelectric unit that we recently commemorated in Argentina. The device can also be used for commercial purposes. ...Read more »

Hydraulic turbine model test bench plays an important role in the development of hydropower technology. It is an important equipment to improve the quality of hydropower products and optimize the performance of units. The production of any runner must first develop a model runner and test the mod...Read more »

Composite materials are making inroads in construction of equipment for the hydroelectric power industry.
