After proper justification, if changing the requirements of a clause in this document will not endanger the safety of the wind turbine, then the clause may be changed. payment. However, this provision does not apply to the classification and related definitions of external conditions in Chapter 6.Compliance with the requirements of this document does not relieve any individual The responsibility of a person, organization or group to comply with other applicable standards or regulations. This document does not give requirements for offshore wind turbines, especially for supporting support structure. For offshore wind power facilities, refer to the IEC 61400-3 series of standards. GB/T 18451 establishes the minimum Design requirements and structural design, involving control and protection functions, internal electrical systems, mechanical systems and support structures, etc., are determined by design requirements and power The characteristic test consists of two parts. ---GB/T 18451.1 Design requirements for wind turbines. The purpose is to provide uniform design requirements to ensure wind power generation The standardization of unit design prevents various hazards from causing damage to the wind turbine unit. ---GB/T 18451.2 Wind Turbine Power Characteristics Test. The purpose is to clarify the power characteristic test of wind turbine Requirements and methods to verify the power generation performance of wind turbines designed in accordance with Part 1. Wind Turbine Design Requirements1 ScopeThis document specifies the design requirements necessary to ensure the structural integrity of wind turbines. Its purpose is to determine the life expectancy of the wind turbine During the service life, an appropriate level of protection is provided to prevent damage to the wind turbine from various hazards. This document deals with the various subsystems of the wind turbine, such as control and protection functions, internal electrical systems, mechanical systems and support structures. This document applies to wind turbines of all capacities. For small wind turbines, refer to IEC 61400-2. IEC 61400-3-1 imposes additional requirements on the installation of offshore wind turbines. This document can be used together with the IEC and ISO standards mentioned in Chapter 2.2 Normative referencesThe contents of the following documents constitute the essential provisions of this document through normative references in the text. Among them, dated references For documents, only the version corresponding to the date is applicable to this document; for undated reference documents, the latest version (including all amendments) is applicable to this document.
