IEC TS 61400-28:2025规定了行动、调查和评估的最低要求，以确保风电场资产（特别是风力涡轮机）的持续结构完整性，旨在验证人员操作它们仍然安全。该文件描述了如何维护这些资产并收集适当的证据，以向第三方证明风险被最小化，特别是在风险与附带损害或伤害相关的情况下，例如风电场附近的人员或结构可能遭受的损害或伤害。本文件涵盖了对当前状况和剩余使用寿命的评估，为证明结构或主要部件和系统在设计寿命（定义见3.1.3）和特定地点评估寿命（以较短者为准）之外的延长运行提供了技术依据，以证明对安全系统初级层有贡献。

IEC TS 61400-28:2025 sets out minimum requirements for actions, investigations and assessments to ensure the continued structural integrity of wind farm assets, particularly wind turbines, aimed at verifying that they remain safe for personnel to operate. The document describes how to maintain those assets and collect suitable evidence to demonstrate to third parties that risks are minimised, particularly where risks are related to collateral damage or injury, such as could be suffered by personnel or structures neighbouring the wind farm. Covered in this document are assessments of current condition and remaining useful life, resulting in the technical basis for justifying extended operation beyond the design life (defined in 3.1.3) and also beyond the site-specific assessed lifetime, whichever is shorter, for structural or major components and systems contributing to primary layer of the safety system.
