IEC 61400-12-1:20 17 RLV包含国际标准及其红线版本。红线版本只有英文版本。Redline版本为您提供了一种快速简单的方法来比较该标准与其前一版本之间的所有变化。红线版本不是IEC官方标准，只有标准的当前版本才被视为官方文件。 IEC 61400-12-1:20 17规定了用于测量单个风力涡轮机的功率性能特征的程序，并且适用于连接到电力网络的所有类型和尺寸的风力涡轮机的测试。此外，该标准描述了用于确定小型风力涡轮机（如IEC 61400-2中定义的）在连接到电网或电池组时的功率性能特性的过程。该程序可用于特定位置的特定风力涡轮机的性能评估，但同样地，当考虑到特定地点的条件和数据过滤影响时，该方法可用于在不同风力涡轮机模型或不同风力涡轮机设置之间进行一般比较。与上一版相比，新版本包括以下重大技术变化:风速的新定义、风切变和风转向的纳入、空气密度修正的修订、场地校准的修订、功率曲线定义的修订、仓中心法的插值、障碍物模型的修订等。 关键词:风力发电机、风能、可再生能源、性能、效率

IEC 61400-12-1:2017 RLV contains the International Standard and its Redline version. The Redline version is available in English only. The Redline version provides you with a quick and easy way to compare all the changes between this standard and its previous edition. The Redline version is not an official IEC Standard, only the current version of the standard is to be considered the official document.

IEC 61400-12-1:2017 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 wind turbines at specific locations, but equally the methodology can be used to make generic comparisons between different wind turbine models or different wind turbine settings when site-specific conditions and data filtering influences are taken into account. This new edition includes the following significant technical changes with respect to the previous edition: new definition of wind speed, inclusion of wind shear and wind veer, revision of air density correction, revision of site calibration, revision to definition of power curve, interpolation to bin centre method, revision of obstacle model, etc.
