GB/T 13981-2009Design general requirements for small wind turbine (English PDF)

Foreword

This standard replaces GB/T 13981-1992 "General requirements for wind turbine design." This standard compared with GB/T 13981-1992 main changes are as follows:

--- Standard name to "small wind turbine design General requirements";

--- Chapter 1 - Chapter 3 to

1 Scope

GB/T 13981-2009 is the Chinese national standard on design general requirements for small wind turbine, in the field of energy and heat transfer engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 13 April 2009 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 January 2010. Classification: ICS 27.180, CCS F11. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

General This standard specifies the design, environmental conditions, aerodynamic design, load, strength criterion and structure design of small wind turbine. This standard applies to rotor swept area is less than or equal to an upwind horizontal axis wind turbine design 200m2; the other type of wind turbine You can use and reference.
