GB/T 19068.1-2017Small wind turbines—Part 1: Technical condition (English PDF)

Foreword

GB/T 19068 "small wind turbine" is divided into the following three sections.

--- Part 1. Technical conditions;

--- Part 2. Test methods;

--- Part 3. Wind tunnel test methods.

This section GB/T 19068 Part 1.

This section drafted in accordance with GB/T 1.1-2009 given rules.

This Part replaces GB/T 19068.1-2003 "off-grid wind turbine generator Part 1 Technical conditions." This section compared with GB/T 19068.1-2003, in addition to editorial changes outside the main technical changes are as follows.

--- Expand the scope of this section (see Chapter 1, 2003 edition Chapter 1);

--- Adjust the contents of the generator unit (see 4.1.5, 2003 version 3.3.9);

--- Reflects the GB/T 17646 design grade grading ideas and methods and modify the working conditions of the content (see 4.2, 2003 edition Of 3.2);

--- Revised cut-in wind speed and rated wind speed requirements (see 4.3.1, 2003 version 3.3.1);

--- Modify the maximum working speed of the unit requirements (see 4.3.6, 2003 version 3.3.6);

--- Increase the wind turbine wind turbine utilization factor and the efficiency of the machine prerequisites, modify the machine efficiency requirements (see 4.3.9 and 4.3.10 and 2003.12 and 3.3.13);

--- Removed the rotor unit swept area material requirements (see 2003 version 3.3.14);

--- Adjust the contents of the cables and wires (see GB/T 19068.2-2017 5.4.5, this part of the 2003 edition of 3.3.17);

--- Increased power characteristics of the test requirements (see 4.3.14);

--- Increased durability test requirements (see 4.3.15);

--- Adjust and modify the contents of the safety requirements (see 4.4, 2003 version 3.1.6, 3.3.7 and 3.3.11);

--- The technical manual in the documentary requirement adds the power characteristic curve and the reference annual power generation (AEP) requirement [see 5.3c) and d)];

--- Increased unit nameplate (SWT) level requirements (see 6.2).
