Pelton turbine Knowledge

In 1880, Lester Pelton applied for a patent for the turbine named Pelton. Pelton turbine is very suitable for high head and relatively low flow. It is easy to adjust and guarantees the best efficiency within partial load range.

Turgo turbine Knowledge

Turgo turbine was improved and invented by Gilbert Gillke on the basis of Pelton in 1919.

Francis Turbine Knowledge

Francis turbine belongs to a type of reaction hydraulic turbine, and is invented by American engineer Francis in 1849, also known as Francis turbine.Water radially flow into runner from all around, and then flow out runner approximately axially.Runner consists of crown, band and blade.The development trends in recent years are high head, large capacity, high specific speed and high efficiency.

Kaplan Turbine Knowledge

It is named after its great inventor, Victor Kaplan, and continues to shape modern hydroelectric power generation on a global scale. After the Austrian developed the Kaplan turbine from the Francis turbine, he first showed this turbine to the public in 1913. This technological innovation can

Tubular turbine Knowledge

Shaft extension Tubular unit was invented by by German Kuhne in1930 and was patented. Generator of this unit is installed outside the flow channel,so this unit has feature of convenient installation, repair and maintenance, and is widely used in medium and small hydropower with low

Inlet valve knowledge

In the water passing system of turbine , according to the needs of operation and maintenance for the hydropower station, corresponding valve is installed at the connecting position between penstock and turbine, and the valve installed in front of the turbine spiral casing is usually called the

Hydraulic turbine governor Knowledge

Governor of turbine is one of the most important auxiliary control equipment of hydraulic generating set, its operation quality directly determines safety and stable operation of unit. Reducing fault rate of turbine governor is the most effective method to improve reliability of unit operation.

Generator knowledge

Hydrogenerator refers to the generator that uses turbine as the prime motor to convert water energy into electric energy. When the water flows through the turbine, the water energy is converted into mechanical energy, and the shaft of the turbine drives the rotor of the generator, and then

Excitation System knowledge

Excitation system of generator is the general name of the power supply which provide excitation current of synchronous generator,and its auxiliary equipment. Excitation system is commonly composed of two main parts: excitation power unit and excitation regulator. Excitation system of

SCADC Knowledge

SCADA (Supervisory Control And Data Acquisition) system, that is, data acquisition and monitoring control system. The SCADA system is DCS based on computer and power automation monitoring system.This system has a wide range of applications and can be applied to many fields such
