Wind turbine generator encoder

Introduction to wind turbine encoders

One OEM uses a pulse encoder on each rotor blade and one to track where the turbine is pointing. The main control system uses position information to optimize generator speed relative to wind speed and direction.

6 FAQs about [Wind turbine generator encoder]

Why do wind turbines need encoders?

It turns out that high vibration and temperature extremes kill even “heavy duty” optical encoders. So to handle such loads, encoder manufacturers have designed units just for wind turbines. Yaw control, which lets the turbine face into the wind. Generator feedback and blade-pitch-control applications are considered mission critical.

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.

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 shaft encoder?

A common application is inside the turbine hub on pitch control units. Encoders are mounted behind pitch motors and brakes or directly engage the blade crown gear. Shafted encoders are picked for these applications as well as hollow-shaft devices. Of the recent encoders, one version for generators is intended for harsh conditions.

Why do wind turbine generators need high-resolution speed feedback?

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.
