Hydropower Knowledge

The “Generator Operation Regulations” issued for the first time by the former Ministry of Power Industry provided a basis for the preparation of on-site operation regulations for power plants, stipulated uniform operation standards for generators, and played a positive role in ensurin...Read more »

Hydro generator is the heart of hydropower station. Water turbine generator unit is the most critical main equipment of hydropower plant. Its safe operation is the fundamental guarantee for hydropower plant to ensure safe, high-quality and economic power generation and supply, which is directly r...Read more »

Hydro generator is a machine that converts the potential energy and kinetic energy of water flow into mechanical energy, and then drives the generator into electrical energy. Before the new unit or overhauled unit is put into operation, the equipment must be comprehensively inspected before it ca...Read more »

Structure and installation structure of hydraulic turbine Water turbine generator set is the heart of hydropower power system. Its stability and security will affect the stability and security of the whole power system and the stability of power supply. Therefore, we need to understand the struct...Read more »

The unstable operation of hydraulic turbine unit will lead to vibration of hydraulic turbine unit. When the vibration of hydraulic turbine unit is serious, it will have serious consequences and even affect the safety of the whole plant. Therefore, the stability optimization measures of hydraulic ...Read more »

As we all know, water turbine generator set is the core and key mechanical component of hydropower station. Therefore, it is particularly important to ensure the stable operation of the whole hydraulic turbine unit. There are many factors that affect the stability of hydraulic turbine unit, which...Read more »

In the last article, we introduced a resolution of DC AC. the “war” ended with the victory of AC. therefore, AC gained the spring of market development and began to occupy the market previously occupied by DC. After this “war”, DC and AC competed in the Adams hydropower st...Read more »

As we all know, generators can be divided into DC generators and AC generators. At present, alternator is widely used, and so is hydro generator. But in the early years, DC generators occupied the whole market, so how did AC generators occupy the market? What’s the connection between hydro ...Read more »

The world’s first hydroelectric power station was built in France in 1878 and used hydroelectric generators to generate electricity. Until now, the manufacture of hydroelectric generators has been called the “crown” of French manufacturing. But as early as 1878, the hydroelectri...Read more »

Electricity is the main energy obtained by human beings, and the motor is to convert electric energy into mechanical energy, which makes a new breakthrough in the utilization of electric energy. Nowadays, motor has been a common mechanical device in people’s production and work. With the de...Read more »

Compared with steam turbine generator, hydro generator has the following characteristics: (1) The speed is low. Limited by the water head, the rotating speed is generally less than 750r / min, and some are only dozens of revolutions per minute. (2) The number of magnetic poles is large. Because t...Read more »

Reaction turbine is a kind of hydraulic machinery that converts hydraulic energy into mechanical energy by using the pressure of water flow. (1) Structure. The main structural components of reaction turbine include runner, headrace chamber, water guide mechanism and draft tube. 1) Runner. Runner ...Read more »
