Head of Test and Validation within Innovation Alstom Wind, the mission of department is to lead Validation of prototype units in both platforms, Offshore & Onshore. Responsibilities comprise as mainly goals Validation Plans, Commissioning and Prototype Sites Management. The area is formed by a group specialized in Instrumentation & Data Processing; another focused in Field Test activities and finally Validation Engineers ensuring the validation life-cycle.
Main achievements of team have been prototype units ECO100 and ECO86 in USA country, ECO100 and ECO110 in Spain; and nowadays HAL150 6MW in France plus ECO122 in Netherlands.

Abstract

Haliade150 6MW long term experimental characterization: multi-disciplinary approach covered by an integral solution

Introduction

Wind turbines are increasingly demanding more mature methodologies for experimental validation from a multi-disciplinary approach (loads, electrical, mechanics, thermal, dynamics and turbine controller including field-bus plus logical control) being a key point to be able to characterize and validate the wind turbine performance as a whole system and respecting V-Cycle including sub-systems and components.

Approach

Furthermore, rapid comparison or checks are required during the commissioning phase of the prototypes which obliges to develop powerful tools to cover these needs. Good validation practices involve not only increasing the number and type of measurement points but also the level of parameters and algorithms. Therefore, complete validation enlarges the range of test cases causing unavoidable long term testing campaigns.

Main body of abstract

To be able to fully characterize the wind turbine it is necessary to have an integral solution which allows correlating all the experimental data with the expected values coming from design numerical models. Given that databases are collected during a long term period, the management, synchronization, data mining, report and analysis of high volume of data is not obvious. Additionally, in order to permit a high level of analysis and interpretation, the method and tools should consider the possibility to integrate numerical data coming from simulation codes. These data should be analysed and post-processed using the same methodology and algorithms which will be used to analyse the experimental data. This additional capability reduces uncertainties during the process of validation and comparison of experimental data with the numerical data. It is also important to remark that harmonisation of methodologies between designs and testing is an added value to this proposed solution.

Conclusion

Due to the fact that no market solutions were covering Alstom Wind Innovation validation requirements, an integral solution was internally developed and will be presented in this paper. Haliade 150 6MW wind turbine prototype installed at Le Carnet, France, has been fully instrumented and experimentally characterized through experimental campaigns accomplishing the goal assigned to site validation.


Learning objectives
The acquired data has been merged respecting synchronization and offering an innovative visualization plus reporting solution of large datasets; allowing analysis through internal tools maximizing the transversal impact of analysis oriented to be multi-user and multi-discipline.
