Introduction

The wind turbine certification standard GB/Z 25458 introduces the general rules and procedures for wind turbine combination certification Evaluation modules under the three different types of certification of power generator set type certification, component certification and project certification Content. As one of the evaluation modules for unit type certification --- design certification, the module diagram of the design evaluation certification process is shown in Figure 1.

Figure 1.Module diagram of design evaluation certification process

For the mechanical components and key structural parts of wind turbines, the standard states that the certification body should comply with GB/Z 25458, GB/T 18451.1 and GB/T 31517 for design evaluation, and especially pointed out that the evaluation of the gearbox is based on the standard GB/T 19073. But for key structural parts, Because there is no specific design standard, how to conduct design evaluation, the above standards lack specific guidance.

This standard takes into account the relevant requirements of GB/Z 25458, GB/T 18451.1 and GB/T 31517, and Based on the evaluation method of key structural parts, the design evaluation process, methods and specific requirements of each evaluation link for key structural parts are specified.

Make the design and evaluation of key structural parts rule-based. This helps to unify the design assessment requirements and Method, and thus improve the quality level of critical structural design assessment. In addition, this standard can also be used as a the basis for communication when conducting critical structural design assessments.
