Presenter's biography

Biographies are supplied directly by presenters at EWEA 2015 and are published here unedited

Mrs. Sabre is a climatologist working in the building company of the CSTB for 13 years in the CAPE department. She studies the impact of climate on the natural and built environments at the University of Jussieu in Paris. An important part of her job is to analyze the wind and its impacts on structures under all aspects. She has participate to the revision of the IEC-61400-2 and also to the redaction of the recommended practices for wind turbine testing and evaluation of the task 27 of the IEA wind group.

Abstract

A new testing French site for qualification of small wind turbines - The CREPE

Introduction

The market of the small wind energy in France is in full development but is at present submitted to no regulations. The purpose is to propose another testing site for small wind turbine that follows international rules.

Approach

It is onto this fact that the CSTB of Nantes gave for objective to create a Center of testing and research for the small wind energy (CERPE in French). At the international level a standard exists, the IEC-61400-2. The working group Task 27 of the IEA Wind has proposed a new consumer label for small wind turbines as recommended practices for wind turbine testing and evaluation. Those 2 documents are the base of the development of the CREPE.

Main body of abstract

The site of CREPE is located close to the city of Bouin in the Vendée department (85) at 46km south-west from Nantes at less than 1km from the sea. It is an open site with no tall vegetation nor houses in the neighborhood. It exists since the 80s and small wind turbines were tested already within the framework ELOISE. The aim is from now to redo it by following the rules of the art proposed by the standards. The procedure has followed several steps. The first ones were focused on the characterization of the site (instrumentation, assessment of the wind resource, classification, security, maintenance…). The second is to install a new small wind turbine to validate the whole procedure by putting forward the key points and the weak points and especially to identify deviations from the standards. This second step is supported by the AEROJOULES project financed by the Region Pays de la Loire. A small vertical axis wind turbine is installed on the CREPE site for a 6-month period, after the validation in the CSTB/Nantes wind tunnel, for two purposes. The first is to validate the process and the second is to test the performances of this prototype of small wind turbine. The third step will be the acceptance of the CREPE site to be able to propose to the manufacturer the IEA label and the last step, the accreditation following the standards (ISO/IEC-17025:2005 and IEC-61400 series).There are four steps in this process and the present work detailed step one and two.

Conclusion

The AEROJOULES project has allowed us to create the CREPE site for research, development and testing small wind turbines. The recommended practices proposed by the IEA Task 27 group are the first step to go to the certification of small wind turbines because this doesn’t exist yet in France. There are four steps in this process and the present work detailed step one and two and give the perspectives of the step three and four.


Learning objectives
To validate the ability of the field site as CREPE to qualify small wind turbines
To confirm our capacity to qualify small wind turbines before their launch on the market by following as much as possible the standards recommendations
To put forward the problems to follow the international standard's recommendations
To launch on the market reliable small wind turbines
