PERFORMANCE OPTIMIZATION
MAXIMISE THE PERFORMANCE AND LONGEVITY OF YOUR WIND FARM
This service is designed to address the major challenges faced by wind farm owners and operators: continuous performance optimisation and asset life extension.
PERFORMANCE OPTIMIZATION
OUR OBJECTIVES
Improve the service life of wind farms and optimise their performance.
Measure and correct aerodynamic and mass imbalances for increased rotor efficiency.
Reduce nacelle oscillations.
Reduce fatigue in critical components (such as yaw, foundations, gearboxes, bearings, towers) and preserve their integrity and service life.
Reduce low-frequency vibrations, thereby helping to reduce noise pollution.
Improve overall fleet performance by reducing the need for component replacement and machine downtime.
Optimise aerodynamic flow within the rotor.
Support our customers in fatigue calculations and extending the service life of ageing wind farms, which were initially designed for a 20-year lifespan.
HOW WE WORK
DETAILED DESCRIPTION
CORRECTION OF AERODYNAMIC AND MASS IMBALANCES
- Diagnosis of imbalances via low-frequency vibration measurements carried out on 100% of turbines.
- Detection of aerodynamic and mass imbalances.
- Precise measurement of blade angle deviations (absolute and relative) using photometry, with an accuracy of +/- 0.1°.
- Identification of blades and allocation of measured deviations for immediate correction.
- Adjustment of blade angles using photometry to eliminate aerodynamic imbalances (affecting approximately 30%
of turbines). - Mass balancing of the rotor using test weights, with vibration measurements taken before and during
balancing. - Final correction of mass imbalance by installing specific weights, adapted to the type of machine.
- Validation of the adjustment by turbine operators, based on the acceptability of vibration measurements.
EXTENDING THE LIFESPAN OF ASSETS
- Implementation of specialised fatigue calculation services to assess and extend operational lifespan.
- Detailed modelling of each turbine using ADCoS aerodynamic software.
- Comprehensive assessments of machines during in-depth technical inspections, focusing on:
- Fatigue in critical components.
- Risks specific to the turbine type.
- Risks inherent in operating conditions.
