Foreword

The creation of the document is for the purpose of standardization of the load calculation for UP wind turbines. Besides that, it's also used as part of the load template report for the certification.

The document is created by the Department of Load Strength and Structure.

The document is used only in the UP Co. Ltd, and is prohibited to spread without permission.

1. Scope

This Design Load Cases Tables apply to the load calculation and preparation of the load report for UP wind turbines. The creation of the Tables is based on GL2010 and also refer to the standard of IEC 61400-1(2005).

The figures in the tables are only as an example, for a particular wind turbine it requires addition analysis whether it's applicable.

2. Normative references

The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. GL2010 Guideline for the Certification of Wind Turbines- Part 4 Load Assumptions IEC61400-1:2005 Wind turbines - Part 1 Design requirements

3. Load Case Descriptions

The tables give the case name, the initial turbine state, the initial conditions (wind speed,
