Summary This standard applies to wind turbine load measurements, mainly for horizontal axis wind turbine (wind turbine swept area> 40m2). The method described here can also be used for other wind turbine (such as wind water pumping machines, vertical axis wind turbine). The purpose of this guidance document is to provide technology wind turbine load measurement methods and related technologies. The technical guidance document can be used as a measurement guide or direct validation rules to determine structural loads. The technical guidance document can be used as a measure of normative documents.

Foreword

This instructional technical document has been prepared for this purpose. --- Promote the standardization of wind turbine and wind turbine international standardization work; --- Improve the test capability and level of wind turbine mechanical load, promote the improvement of wind turbine product quality, improve product Market Competitiveness. The revised technical documents adopted IEC TS61400-13.2001 "wind turbine generator 13th part of the mechanical load measurement" (English version). This instructional document is redrafted in accordance with IEC TS 61400-13.2001. Poor editing with IEC TS61400-13.2001 Different. 1) 1.1,1.2,1.3,1.4 in Chapter 1 of the original text should be changed to the range of 1, 2 normative references, 3 terms and definitions Meaning, 4 symbols, units and abbreviations; 2) Change chapter 2 of the original text to .5 test safety; change chapter 3 to .6 measuring load; and so on. For ease of use, the following technical amendments have been made to the guidance document. a) Replace "This Part of IEC TS 61414" with this Guidance Document; b) Use the decimal "." instead of the comma "," as the decimal point; c) deleted the IEC foreword and introduction; d) Added the preface to this guidance document; Appendix A, Appendix B, Appendix C, Appendix D of this guidance document are informative appendices.
