Technical committeeTypeAcronymIEC 61400-24CommitteePublished year2010Description
IEC 61400-24:2019 applies to lightning protection of wind turbine generators and wind power systems. Refer to guidelines for small wind turbines in annex.
This document defines the lightning environment for wind turbines and risk assessment for wind turbines in that environment. It defines requirements for protection of blades, other structural components and electrical and control systems against both direct and indirect effects of lightning. Test methods to validate compliance are included.
Guidance on the use of applicable lightning protection, industrial electrical and EMC standards including earthing is provided.
This second edition cancels and replaces the first edition, published in 2010. This edition includes the following significant technical changes with respect to the previous edition:
a) it is restructured with a main normative part, while informative information is placed in annexes. -
Technical committeeTypeAcronymIEC 61400-23:2014CommitteePublished year2014Description
IEC 61400-23:2014 defines the requirements for full-scale structural testing of wind turbine blades and for the interpretation and evaluation of achieved test results. The standard focuses on aspects of testing related to an evaluation of the integrity of the blade, for use by manufacturers and third party investigators. The following tests are considered in this standard: - static load tests; - fatigue tests; - static load tests after fatigue tests; - tests determining other blade properties. The purpose of the tests is to confirm to an acceptable level of probability that the whole population of a blade type fulfils the design assumptions.

IEC 61400-21-1:2019 includes: - definition and specification of the quantities to be determined for characterizing the electrical characteristics of a grid-connected wind turbine; - measurement procedures for quantifying the electrical characteristics; - procedures for assessing compliance with electrical connection requirements, including estimation of the power quality expected from the wind turbine type when deployed at a specific site. The measurement procedures are valid for single wind turbines with a three-phase grid connection. The measurement procedures are valid for any size of wind turbine, though this part of IEC 61400 only requires wind turbine types intended for connection to an electricity supply network to be tested and characterized as specified in this part of IEC 61400. This first edition cancels and replaces the second edition of 61400-21 published in 2008. This edition includes the following new items with respect to 61400-21: a) frequency control measurement; b) updated reactive power control and capability measurement, including voltage and cos φ control; c) inertia control response measurement; d) overvoltage ride through test procedure; e) updated undervoltage ride through test procedure based on Wind Turbine capability; f) new methods for the harmonic assessment.

Technical committeeTypeAcronymIEC 61400-1:2019 RLVCommitteePublished year2019KeywordsDescription
IEC 61400-1:2019 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 61400-1:2019 specifies essential design requirements to ensure the structural integrity of wind turbines. Its purpose is to provide an appropriate level of protection against damage from all hazards during the planned lifetime. This document is concerned with all subsystems of wind turbines such as control and protection functions, internal electrical systems, mechanical systems and support structures. This document applies to wind turbines of all sizes. For small wind turbines, IEC 61400-2 can be applied. IEC 61400-3-1 provides additional requirements to offshore wind turbine installations. This document is intended to be used together with the appropriate IEC and ISO standards mentioned in Clause 2. This edition includes the following significant technical changes with respect to the previous edition: a) general update and clarification of references and requirements; b) extension of wind turbine classes to allow for tropical cyclones and high turbulence; c) Weibull distribution of turbulence standard deviation for normal turbulence model (NTM); d) updated design load cases (DLCs), in particular DLC 2.1 and 2.2; e) revision of partial safety factor specifications The contents of the corrigendum of September 2019 have been included in this copy.
