Wind turbine blade control system

4 FAQs about [Wind turbine blade control system]

How many wind turbines are equipped with the bladecontrol® system?

Around 5,450 onshore and 450 offshore wind turbines are currently equipped with the BLADEcontrol® system. Dr. Daniel Schingnitz, Head of Sales and Marketing at Weidmüller Monitoring Systems GmbH, says: “With over 24,200 machine years of experience, we are the experts in the field of rotor blade monitoring.

Why do wind turbine blades need to be adjusted?

However, as wind speeds increase, the blades need to be adjusted to reduce drag and prevent excessive mechanical stress. By altering the blade angle, pitch control systems enable turbines to maintain optimal rotational speed and maximize power output even as wind conditions fluctuate.

How do you control a wind turbine?

Two major systems for controlling a wind turbine. Change orientation of the blades to change the aerodynamic forces. With a power electronics converter, have control over generator torque. To maximize power output, want constant optimal tip speed ratio. As wind speed increases, rotor speed increases.

How is the pitch of a wind turbine controlled?

The pitch angle of the blades is controlled by hydraulic actuators, which are normally powered by hydraulic pumps. Figure 2 shows hydraulic pitch control system. The system may include sensors to measure wind conditions and a controller to analyse the data and adjust the blade pitch accordingly. Fig. 2.
