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.

Application examples

  • Control guide blades in Kaplan turbines

    Smooth turbine operation through reliable control

    The solution

    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.

    The features

    • Extremely reliable
    • No reference run required after voltage interruption
    • Rugged, non-contacting

  • Control guide vanes in Kaplan turbines

    Efficient output adjustment through reliable control

    The solution

    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.

    The features

    • High protection class
    • Pressure-rated for installation inside hydraulic cylinders

  • Control Pelton turbines

    Reliable adjustment of water pressure

    The solution

    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.

    The features

    • Reliable and rugged
    • Compact design

  • Monitor dams

    Precise control of the water level

    The solution

    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.

    The features

    • Large temperature range
    • Analog output 4...20 mA
    • Compact design

  • Monitor rakes

    Robust solution for greater efficiency

    The solution

    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.

    The features

    • High pressure rating
    • Easy to install

  • Reliable closed position

    Reliable detect butterfly valves

    The solution

    Butterfly valves in hydroelectric plants are used to reliably regulate the flow of water. High-pressure rated inductive sensors from Balluff can be installed directly at the sealing edge to verify that the valve is fully closed.

    The features

    • High pressure rating
    • Variety of housing and thread variations
    • With cable or connector
    Reliable detect butterfly valves

  • A single concept for field installation

    One concept for handling field installation for various markets

    The solution

    System building often requires connecting sub-components to the controller over long distances. With IO-Link just one concept is capable of handling field installation for various markets. To adapt the bus system, simply deploy the desired master. The circuit diagrams remain unchanged.

    The features

    • One fieldbus/IP address for up to 136 I/O signals and diagnostic points
    • Digitized analog values instead of analog signals (no shielded cable necessary)
    • Control actuators with up to 2 A
