The hydroelectric energy is one of the most common in the field of renewable energy and thanks to the innovation technologies that allow more efficiency and application facility, its diffusion will improve considerably in the next years.
With the main aim to achieve performance, reliability and good value for money, we drive drive things forward to ensure that our plants work maximizing the production of energy while reducing timing e costs as much as possible.
Throughout our solutions we could introduce our know how of of industrial field in the hydroelectric sector that is translated in an important reduction of mechanical components and move the regulation to the electronic part.
The speed system, realized through the combination between AFE and inverter, control the speed and the torque of the generator, allowing in the same time to decrease the mechanical stress and extend the system life: the main effect is an important productivity growth.
Thanks to this technology, with a dedicated software, it is possible to work with a wide range of capacities.
n many sites where the traditional fixed-speed turbine would not be able to meet these requirements, the use of variable speed has made it possible to exploit the site.
The technology is applicable to all types of existing hydraulic machines, from the traditional Pelton, Francis and Kaplan up to the augers. Thanks to the know-how and experience of BDF Industries in the control of electric motors for industrial automation, we are able to control any type of generator with or without position sensor:
- Direct drive synchronous generators with permanent magnets up to 160 poles
- Traditional or vector asynchronous generators
- Reluctance hybrid generators
For a better yield of the hydroelectric plant in some phases of work, we have developed a software called STARTER / BY PASS that allows to disconnect the generator from the electronics during operation at nominal revolutions at 50Hz and directly connect the machine in parallel with the electric network , thus reducing running losses and eliminating starting currents during start-up.
