Precise control of large plants
Hydroelectric power is indispensable among renewable energies these days and still harbours plenty of untapped potential. Mastering the immense forces of the water requires reliable closed-loop systems that work with the utmost precision.
Balluff supports and protects advanced turbine and control concepts with high-precision solutions comprising sensors and position measurement systems.
To ensure that the turbines run smoothly, the position of the guide blades in Kaplan turbines is adjusted as needed. Our BTL profile magnetostrictive linear position sensors allow you to reliably and safely control your turbines.
By adapting the rotor blades to the water volume, the turbine efficiency of Kaplan turbines is adjusted. Our BTL magnetostrictive linear position sensors are directly integrated into the shaft and thereby ensure optimum adjustment of the impeller. This makes it possible to efficiently control the output of your turbines.
In Pelton turbines, the speed of the impeller, and thus the output produced, is controlled via nozzles in the water jet. At several inlet nozzles there is high pressure of up to 200 bar, which has to be adjusted quickly and evenly. This is done by Balluff's BTL magnetostrictive linear position sensors – with high reliability.
By now, fully automatic control of the water level is standard in dams. Here, our BSI inclination sensors precisely detect the intermediate position and thereby reliably monitor your dams.
Floating debris at the infeed end of hydroelectric power plants can cause efficiency loss. In worst-case scenarios they can even cause downtimes. In the flotsam screen, our BHS pressure-rated inductive sensors detect the end positions of the screen and monitor them reliably. An important contribution to the efficiency of your plant.
