风能发电系统 第50-4部分：使用浮动激光雷达系统进行风力测量

[中文适用范围]： IEC 61400 的本部分（技术规范）旨在描述确保使用浮动式测风激光雷达系统进行测风并报告的程序和方法，并遵循最佳实践。本文件未规定测风的目的或用例。然而，由于本文件是 IEC 61400 系列标准和技术规范的一部分，预计测风将用于某种形式的风能测试或资源评估。本文件的范围仅限于在浮标内或浮标上垂直剖面测风激光雷达设备。本文件旨在适用于任何类型和品牌的浮动式测风激光雷达系统。本文件中提供的方法和要求与系统的型号、类型和测量原理无关，并允许应用于新推出的浮动式测风激光雷达系统。IEC 61400 的本部分旨在描述使用浮动式测风激光雷达进行的测风，其质量足以满足风资源评估的用例。本文档的读者可以考虑其他可能具有其他特定要求的用例。关于海洋气象测量的详细指导超出了本文档的范围。 [外文原描述]： IEC TS 61400-50-4:2025 describe procedures and methods which ensure that wind measurements using floating wind lidar systems are carried out and reported consistently and according to best practice. This document does not prescribe the purpose or use case of the wind measurements. However, as this document forms part of the IEC 61400 series of standards and technical specifications, it is anticipated that the wind measurements will be used in relation to some form of wind energy testing or resource assessment. The scope of this document is limited to vertically profiling wind lidar devices in or on buoys. This document aims to be applicable to any type and make of floating wind lidar system. The method and requirements provided in this document are independent of the model and type and of the measurement principle and allow application to new types of floating wind lidar systems as these become available. This part of IEC 61400 aims to describe wind measurements using floating wind lidar with sufficient quality for the use case of wind resource assessment. Readers of this document can consider other use cases that can have other specific requirements.
