With a hydroelectric generator, the kinetic energy of the water is converted into electrical energy. Turbines convert hydropower into electrical energy.
In order to generate energy, the water is directed down a slope to turbines or water wheels. They in turn, drive an electrical generator that converts the kinetic energy into electricity. How much electricity a hydroelectric generator produces depends on various factors. The more water flows through the turbines, the more electricity can be generated. The height of the gradient is also decisive: the higher the gradient, the greater the efficiency. The amount of electricity generated depends primarily on the amount of flowing water and the height difference. With the latest technology, a hydroelectric generator today can achieve an efficiency of over 90 percent.
Hydropower is economical
Types of Hydroelectric Generators
Small power plant – watermill
Why has a technology that has proven itself for centuries been almost forgotten? In these structures, running water drives a wheel that using gears turns a generator.
Available in all sizes.
The screw turbine has minimal environmental disturbances, is environmentally friendly (no river bed change, high fish tolerance) and has a long service life. Swallowing capacity from 0.1 a 5.5 m3 / s and a head of up to 10 m.
Pico Hydroelectric Generator / Pelton Turbine
It is recommended to go with this variant of hydroelectric generator! The usable output is determined by the hydraulic parameters, water volume and net head. A Pelton turbine has a horizontal impeller arrangement. The discharge takes place via a pipe on which the turbine is placed. The water supply line is connected to bayonet couplings. Depending on the amount of water available, up to three nozzles are possible. The water leaves the turbine without pressure. These power plants are very compact and maintenance-free, simple, robust construction, low maintenance, no wearing parts suitable for drinking water, easily customizable, can be combined very well with photovoltaics, light weight, good efficiency, inexpensive.
