This document presents measurement procedures that enable noise emissions of a wind turbine to be characterised. This involves using measurement methods appropriate to noise emission assessment at locations close to the machine, in order to avoid errors due to sound propagation, but far away enough to allow for the finite source size. The procedures described are different in some respects from those that would be adopted for noise assessment in community noise studies. They are intended to facilitate characterisation of wind turbine noise with respect to a range of wind speeds and directions. Standardisation of measurement procedures will also facilitate comparisons between different wind turbines. The procedures present methodologies that will enable the noise emissions of a single wind turbine to be characterised in a consistent and accurate manner. These procedures include the following: - location of acoustic measurement positions; - requirements for the acquisition of acoustic, meteorological, and associated wind turbine operational data; - analysis of the data obtained and the content for the data report; and - definition of specific acoustic emission parameters, and associated descriptors which are used for making environmental assessments. This International Standard is not restricted to wind turbines of a particular size or type. The procedures described in this standard allow for the thorough description of the noise emission from a wind turbine. A method for small wind turbines is described in Annex F.

This part of IEC 61400 deals with safety philosophy, quality assurance, and engineering
integrity and specifies requirements for the safety of small wind turbines (SWTs) including
design, installation, maintenance and operation under specified external conditions. Its
purpose is to provide the appropriate level of protection against damage from hazards from
these systems during their planned lifetime.
This standard is concerned with all subsystems of SWTs such as protection mechanisms,
internal electrical systems, mechanical systems, support structures, foundations and the
electrical interconnection with the load. A small wind turbine system includes the wind turbine
itself including support structures, the turbine controller, the charge controller / inverter (if
required), wiring and disconnects, the installation and operation manual(s) and other
documentation.
While this standard is similar to IEC 61400-1, it does simplify and make significant changes in
order to be applicable to small wind turbines. Any of the requirements of this standard may be
altered if it can be suitably demonstrated that the safety of the turbine system is not
compromised. This provision, however, does not apply to the classification and the associated
definitions of external conditions in Clause 6. Compliance with this standard does not relieve
any person, organisation, or corporation from the responsibility of observing other applicable
regulations.
This standard applies to wind turbines with a rotor swept area smaller than or equal to
200 m2, generating electricity at a voltage below 1 000 V a.c. or 1 500 V d.c. for both on-grid
and off-grid applications.
This standard should be used together with the appropriate IEC and ISO standards (see
Clause 2).

This part of IEC 61400 specifies additional requirements for assessment of the external conditions at an offshore wind turbine site and specifies essential design requirements to ensure the engineering integrity of fixed offshore wind turbines. Its purpose is to provide an appropriate level of protection against damage from all hazards during the planned lifetime. This document focuses on the engineering integrity of the structural components of an offshore wind turbine but is also concerned with subsystems such as control and protection mechanisms, internal electrical systems and mechanical systems. A wind turbine shall be considered as a fixed offshore wind turbine if the support structure is subject to hydrodynamic loading and it is founded on the seabed. The design requirements specified in this document are not sufficient to ensure the engineering integrity of floating offshore wind turbines. For floating installations, reference is made to IEC 61400-3-2. In the remainder of this document, the term "offshore wind turbine" is assumed to refer to those that are fixed to the seabed. This document should be used together with the appropriate IEC and ISO standards mentioned in Clause 2. In particular, this document is fully consistent with the requirements of IEC 61400-1. The safety level of the offshore wind turbine designed according to this document shall be at or exceed the level inherent in IEC 61400-1. In some clauses, where a comprehensive statement of requirements aids clarity, replication of text from IEC 61400-1 is included.

The purpose is to provide standardised metrics that can be used to create and organise methods for availability calculation and reporting according to the user’s needs. The document provides information categories, which unambiguously describe how data is used to characterise and categorise the operation. The information model specifies category priority for discrimination between possible concurrent categories. Further, the model defines entry and exit criteria to allocate fractions of time and production values to the proper information category. A full overview of all information categories, exit and entry criteria is given in Annex. The document can be applied to any number of WTGSs, whether represented by an individual turbine, a fleet of wind turbines, a wind power station or a portfolio of wind power stations. A wind power station is typically made up of all WTGSs, functional services and balance of plant elements as seen from the point of common coupling. This first edition cancels and replaces IEC TS 61400-26-1:2011, IEC TS 61400-26-2:2014 and IEC TS 61400-26-3:2016.

This Technical Report provides guidance on requirements for the electromagnetic compatibility of wind turbines of all sizes, to assist with achieving compliance with EMC standards. This Technical Report includes guidance on emissions, and for immunity to external disturbances. Safety related aspects are not included in this Technical Report. They are the subject of relevant parts of EN 61400. This Technical Report is applicable to electromagnetic emissions and immunity, both conducted and radiated, in the range 0 Hz to 400 GHz (although generally EMC standards do not at present contain test methods or limits at frequencies above 1 GHz). Fault conditions are not taken into account. This Technical Report does not include test procedures, conditions, limits, or reference values; these requirements are included in relevant parts of EN 61000, which are referred to in this Technical Report where necessary. This Technical Report also provides guidance for wind turbine installations (wind farms or single machines). The electromagnetic compatibility of components within the wind turbine (i.e. within enclosed parts of the wind turbine, which may include the hub, nacelle and tubular tower) with each other is solely a matter for the wind turbine manufacturer. The physical impact of the structure on the reception of radio services in the vicinity needs to be considered as a separate issue, and is not dealt with in this Technical Report. It should be noted that although experience to date has shown that physical interference to broadcasting services has caused the majority of complaints, wind turbines are capable of interfering with all radio services to some extent.

This European Standard specifies requirements for protective measures relating to the health and safety of personnel, relevant to commissioning, operation and maintenance of wind turbines. It does not describe instructions and provisions for safe working during manufacture, transport, assembly and installation of the wind turbine. Requirements are specified regarding – hardware provisions being a part of the turbine such as platforms, ladders, lighting, – manuals and warning signs to accommodate safe and quick operation, inspection and maintenance. The requirements and/or measures specified account for the hazards – of mechanical origin such as falling, slipping, locking in, – of thermal origin (fire) such as burns by flames or explosions, – of electricity such as contact with live parts, – generated by noise such as stress and loss of hearing, – generated by neglecting ergonomic principles in machine design such as unhealthy postures or human errors. This standard is prepared for horizontal axis, grid connected wind turbines. For other concepts (e.g. vertical axis turbines) the principles are still valid, but the specific rules or requirements have to be adjusted to the actual concept. Additional provisions and procedures are necessary for turbines installed in water or offshore. The present document only draws attention to these. Provisions and procedures for lifts and Suspended Access Equipment (SAE) in the turbine tower are not included in this standard. This standard is not applicable to wind turbines manufactured before the date of its publication by CENELEC.
