Pitch battery management system

What is pitch system?

Topic background Pitch System is one of the important components of large wind turbines, it has a very important role for the entire wind turbine system’s security,stability and economy. pitch system is typically equipped with backup power. When the grid power supply stopped, backup power is enabled to ensure proper operation of the pitch.

What is a pitch motion controller?

The pitch motion controller is based on our advanced wind turbine controller platform. Being the centre of the system, it collects all inputs from other components such as sensors, chargers and drives. The pitch motion controller works by command from the wind turbine controller, or independently if communication to the controller is lost.

Why should you choose a pitch system for a wind turbine?

A safe and reliable pitch systems is critical for the wind turbine’s performance and power production. DEIF’s pitch system solution is perfectly developed for wind turbines from 1.5 MW up to 2.5 MW with Aerodyn design.

Are lithium batteries suitable for pitch back-up power?

Lithium batteries have mature technology and cost suitable for using in the pitch back-up power. With the development of lithium batteries, different cathode materials have also been developed, lithium batteries can achieve higher energy density .

Why should I use a hydraulic pitch system?

If you chose to use a hydraulic pitch system, we customise the pitch design perfectly tailored to your wind turbine design in collaboration with our supplier. The primary functions of the pitch system are to optimise the power production and to stop the wind turbine in maintenance and emergency situations.

How does a Deif pitch system work?

DEIF designs the pitch system to individually match the specific wind turbine design in order to optimise the operation under the following conditions; high, medium, low wind and extraordinary situations like LVRT (Low Voltage Ride Through) conditions and emergency stop.
