6 FAQs about [Battery function in pitch control system]
What is a pitch control system in wind turbines?
Today, pitch control systems in wind turbines are a standard component. The pitch control system is continuously adjusting the blade pitch in accordance to the operation strategy of the wind turbine. This ensures constant power output of the wind turbine.
How does a pitch control system work?
Without proper control, these forces could lead to structural damage and reduce the turbine’s lifespan. The Pitch Control System actively counters these stresses by adjusting blade angles in real-time to reduce the load on the structure during turbulent conditions, thereby extending the turbine’s operational life.
How does a pitch motion controller work?
The pitch motion controller works by command from the wind turbine controller, or independently if communication to the controller is lost. The application comprises sensors for monitoring of the pitch system itself and for monitoring the need of service of the wind turbine.
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.
Do wind turbines have a battery control system?
About 35 to 45% of the wind turbines in the field are equipped with a battery electrical pitch control system. Initial costs for battery-based pitch control systems and ultracapacitor-based systems are equal today. Battery based systems are likely to have a sophisticated charging and monitoring system to maximize life and provide battery safety.
