Standards

This part of IEC 61400 specifies a procedure for measuring the power performance characteristics of a single wind turbine and applies to the testing of wind turbines of all types and sizes connected to the electrical power network . In addition , this standard describes a procedure to be used to determine the power performance characteristics of small wind turbines (as defined in IEC 61400-2) when connected to either the electric power network or a battery bank . The procedure can be used for performance evaluation of specific turbines at specific locations, but equally the methodology can be used to make generic comparisons between different turbine models or different turbine settings.

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 part of IEC 61400 presents measurement procedures that enable noise emissions of a wind turbine to be characterized. 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 enough away to allow for the finite source size . The procedures described are different in some respects from those that would be facilitate characterization 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.

This part of IEC 6 1400 includes - definition and specifications of the quantities to be determined for characterizing the power quality of a grid connected wind turbine. measurement procedures for qualifying the characteristics. procedures for assessing compliance with power quality requirements, including estimation of the power quality expected from the wind turbine type when deployed at a specific site, possibly in groups.

This technical specification provides guidelines for the full-scale structural of wind turbine blades and for the interpretation or evaluation of results as a possible part of a design verification of the integrity of the blade.

During the last few years , all major wind turbine manufacture have made desiccated efforts towards development adequate lighting protection systems, and the first experiences with these new designs are beginning to be seen . It is therefore reasonable at the this time to consider and prepare for a standardization effort that will give both manufactures and operators a common framework for appropriate lighting protection of wind turbines.

This International standard covers those aspects to be considered when electrical/electronic/programmable electronic systems (E/E/PESs) are used to carry out safety functions. A major objective of this standard is to facilitate the development of application sector international standards by the technical committees responsible for the application sector. This will allow all the relevant factors, associated whit the applications, to be fully taken into account and thereby meet the specific needs of the application sectors. A dual objective of this standard is to enable the development of electrical/electronic/programmable electronic (E/E/PE) safety-related systems where application sector international standard may not exist.

This part of the IEC 61508 is intended to be used only after a through understanding of IEC 61508-1 which provides the overall framework for the achievement of functional safety.

This part of IEC 61508 - Is intended to be utilized only after a thorough understanding of IEC 61508 -1 and IEC 61508-2. - applies to any soft wear forming part of a safety - related system or used to develop a safety - related systems within the scope of IEC 61508 - 1 and IEC 61508-2 . Such software is termed safety-related software.

This part of the IEC 61508 contains the definitions and explanation of items that are used in part 1 to 7 of the standard 1.1 The definitions are grouped under general headings do that related terms can be understood within the content of each other . But it should be noted that these headings are not intended to add meaning to the definitions , and in this sense the headings should be disregarded.
