What is pitch misalignment?

Pitch misalignment is a condition where a wind turbine blade's physical angle does not match its setpoint. This creates an aerodynamic imbalance that causes uneven loading on the hub and drivetrain, leading to reduced power production and increased structural fatigue.

What causes pitch misalignment?

Common causes include errors during initial turbine assembly or blade installation, mechanical wear in the pitch gearing, and sensor drift or calibration issues within the pitch control system.

How to correct pitch misalignment?

Advanced turbine controls detect rotor imbalances and automatically adjust blade pitch to correct misalignment. This improves energy production (up to 0.7%) while reducing rotor fatigue for more reliable performance.

Power Plant Controller

A PPC to Optimize Energy Production While Maintaining Grid Stability

The Ovation™ power plant controller (PPC) is designed to optimize energy production, enhance efficiency, and maintain grid stability. Utilized across solar farms the controller integrates real-time monitoring, automated adjustments, and predictive analytics to better manage power output, and lower the operational costs of your solar plant.

Tackling Common Plant Control Challenges

Short-term variability in the power generated by solar photovoltaic arrays can negatively affect other generating assets, power quality and grid reliability. The Ovation power plant controller delivers precise ramp rate control to meet grid operator dispatch instructions as a % of plant rated output.
