Generator shaft encoders have a key role in the wind turbine control loop system, and they have to be robust, durable and reliable.

One OEM uses a pulse encoder on each rotor blade and one to track where the turbine is pointing. The main control system uses that position information to optimize generator speed relative to wind speed and direction. It is essential to use reliable components because wind turbines are sited in areas with large temperature fluctuations.

Most applications in the wind turbine will be 1,024 or, on the generator, you’ll see 3,072 ppr. Absolute encoders are a little different, but operate in much the same way. They rotate and output data is relative to their position.

series encoders set standards here when it comes to safety, accuracy and ruggedness – whether in. the drive or as a stand-alone measuring system in wind turbines. The flexible and wide-ranging options offered by the Kübler Sendix encoders create the ideal.

6 FAQs about [Which wind turbine generator encoder is better ]

What is a wind turbine generator encoder?

Generator encoders High-resolution speed feedback in the wind turbine generator system can ensure a stable operation by enabling efficient control of power and torque. Generator shaft encoders have a key role in the wind turbine control loop system, and they have to be robust, durable and reliable.

What is the resolution of a wind turbine encoder?

A common incremental resolution is 1,024 ppr. So for every complete rotation the encoder produces 1,024 pulses. Another common resolution is 2,048 ppr although incremental encoders come in resolutions from 1 to 80,000 ppr. Most wind-turbine applications will be 1,024 ppr. Some OEMs, however, expect 3,072 ppr on the generator.

What is a generator shaft encoder?

Generator shaft encoders have a key role in the wind turbine control loop system, and they have to be robust, durable and reliable. Be it doubly-fed asynchronous or synchronous equipment, the requirements that need to be met by the communications unit in the generator system are constantly increasing.

Are Leine Linde generator encoders easy to install?

The Leine Linde generator encoders are easy to install. Their product design and mounting solutions are well thought-through. For example, the Bearingless 2000 series, which are robust magnetic ring encoders with a diameter up to two meters, were developed especially for the gearless direct drives and hybrid drives of wind turbines.

How to measure the rotational speed of a wind turbine?

No matter if the shaft is large or small, slow or fast, we have the suitable robust encoder! For wind turbines with gearless drives or medium-speed hybrid drives, the simplest and most reliable solution is often to measure the rotational speed by an encoder directly on the main shaft.

What types of encoders are available?

The encoders can be equipped with additional scanning units to enable redundancy or extra output signals if this is of use in the system. And the classic encoder model 862 is also available in the form of a dual output solution, called model 865, providing two electrically isolated output signals from one single casing.
