GB/T 20319-2017Wind turbine generator systems—Specification for acceptance (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 20319-2006 "Acceptance Specification for Wind Turbine Generator." Compared with GB/T 20319-2006 main change As follows.

--- Modify the scope of the standard Chapter 1 (see Chapter 1, 2006 edition Chapter 1);

--- Added terms and definitions (see 3.1 ~ 3.7);

--- Increasing the conditions before acceptance (see 4.1, 4.2);

--- Added Chapter 5 acceptance started (see Chapter 5);

--- Revised the time required for trial operation and assessment indicators (see 6.1, 2006 Edition 4.3);

--- Modify the pre-acceptance inspection items and content (see 6.1, 2006 version 4.4);

--- Modify the final acceptance of the main contents (see 6.2, 2006 version 4.6);

--- Removed the measurement of grounding resistance (see.2006 version 5.3);

--- The provisions of the acceptance criteria based on the content of some of the acceptance method has been revised and moved into the appendix (see 6.1, 7.2, Appendix A, Appendix C, Appendix D, Appendix E);

--- Modify the acceptance of qualified conditions (see 7.1, 7.2, 2006 Edition 4.4,4.6);

--- Modify the acceptance document, and gives the file format for reference (see Chapter 8 and Appendix A, Appendix B, 2006 edition Chapter 6).

1 Scope

This standard specifies the general principles, contents and methods of pre-acceptance and final acceptance after the wind turbine is installed and commissioned for grid-connected power generation.

This standard applies to wind turbine swept area of more than 200m² horizontal axis wind turbine (referred to as "unit").
