Introduction

The purpose of this standard is to provide a unified approach to ensure the consistency of wind turbine sound radiation testing and analysis, accuracy and Repeatability. This standard applies to. ● wind turbine manufacturer, to meet defined noise emission requirements and/or possible reporting standards (such as. IEC /T S61400-14 wind turbine nominal apparent sound power level and sound value); ● wind turbine purchaser to clarify noise requirements; ● wind turbine operators for new or repaired wind turbines, can validate specifications for noise Regulations or requirements; ● wind turbine planning parties and regulators, must be accurate and fair evaluation of noise radiation characteristics of the wind turbine, so that new or It means improved compliance with environmental regulations or licensing criteria. The standard measurement of radiation in the wind turbine noise, analysis and report writing to provide guidance. It will involve wind turbines Group manufacture, installation of the parties, planning, licensing, operation, use and control of the benefit. The standard recommended test and analysis techniques suitable for the above Parties, in order to ensure consistency and accuracy of wind turbine development and operation technologies. Based measurement and reporting standards given in the preparation of this Program can get accurate results that others can duplicate. Wind turbine noise measurement method

1 Scope

This standard provides a measurement procedures to characterize the wind turbine noise emission characteristics. Measurement procedures, including attachments in wind turbines Near the measurement method for evaluating a position suitable for measuring noise emissions, in order to avoid errors caused by sound propagation, while ensuring a sound source with respect to the limited size Measuring distance far enough.

Standardized measurement procedure also facilitates different wind A comparison between the performance of the generator set. Measurement procedure provides a consistent method for accurately measuring single wind turbines noise radiation characteristics. Measuring program comprising. ● positioning acoustic measurement position; ● acoustics, meteorology and wind turbine operation related data collection requirements; ●, the content of the test report on the analysis of the data collected; ● define the specific parameters of noise emissions, as well as the definition of relevant terms when used in environmental assessment. This standard is not limited to a specific capacity or type of wind turbine. Procedures given in this standard can be used comprehensively Description of wind turbine noise emissions. For the measurement of small wind turbine is described in Appendix F.
