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, China’s water and electricity industry has made remarkable achievements from shilongba hydropower station’s installed capacit...Read more »

Generator and motor are known as two different kinds of mechanical equipment. One is to convert other energy into electrical energy for power generation, while the motor converts electrical energy into mechanical energy to drag other objects. However, the two can not be installed and replaced wit...Read more »

The output of the hydro-generator drops Reason In the case 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 same output, the guide vane opening is larger than the original, it is considered that the o...Read more »

In the eyes of many work safety workers, work safety is actually a very metaphysical thing. Before the accident, we never know what the next accident will cause. Let’s take a straightforward example: In a certain detail, we did not fulfill our supervisory duties, the accident rate was 0.001%, and...Read more »

AC frequency is not directly related to the engine speed of hydropower station, but it is indirectly related. No matter what type of power generation equipment, it needs to transmit power to the power grid after generating power, that is, the generator needs to be connected to the grid for power ...Read more »

1. What is the basic function of the governor? The basic function of the governor is: (l) It can automatically adjust the speed of the water turbine generator set to keep it running within the allowable deviation of the rated speed to meet the frequency quality requirements of the power grid. (2)...Read more »

Scraping and grinding of guide bearing bush and thrust bush of small hydraulic turbine is a key process in the installation and repair of small hydropower station. Most of the bearings of small horizontal hydraulic turbines have no spherical structure and thrust pads have no anti weight bolts. As...Read more »
