As an alternative to the power curve measurement of a turbine (IEC 61400-12-1), monitoring the overall performance has both advantages of implementation flexibility, while meeting the requirements of independence and accuracy.
This service, which can be implemented on all or part of a wind farm, according to the configuration of the latter, and which requires a reference measurement station, has the following features :
Performance monitoring of the park as a whole,
Use of elements independent from the manufacturer,
Flexible and economical implementation.
The main applications are the independent control of the overall performance of the park as part of a follow-up phase but also when taking over or at the end of the warranty period of a park.
