范围:IEC 61400的本部分涉及安全理念、质量保证和工程完整性，并规定了小型风力涡轮机（SWT）的安全要求，包括在规定外部条件下的设计、安装、维护和运行。其目的是在这些系统的计划寿命期内，提供适当级别的保护，防止这些系统的危害造成损害。本标准涉及SWT的所有子系统，如保护机构、内部电气系统、机械系统、支撑结构、基础以及与负载的电气互连。小型风力涡轮机系统包括风力涡轮机本身，包括支撑结构、涡轮机控制器、充电控制器/逆变器（如果需要）、接线和断开装置、安装和操作手册以及其他文件。虽然本标准类似于IEC 61400-1，但为了适用于小型风力涡轮机，它确实进行了简化和重大修改。 如果可以适当证明汽轮机系统的安全性没有受到影响，则可以修改本标准的任何要求。然而，本规定不适用于第6条中外部条件的分类和相关定义。遵守本标准并不免除任何个人、组织或公司遵守其他适用法规的责任。本标准适用于转子扫掠面积小于或等于200m2的风力涡轮机，在交流电压低于1000 V或直流电压低于1500 V的情况下发电，用于并网和离网应用。本标准应与适当的IEC和ISO标准一起使用（见第2条）。

Scope: 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 standard is concerned with all subsystems of SWTs such as protection mechanisms, internal electrical systems, mechanical systems, support structures, foundations and the electrical interconnection with the load. A small wind turbine system includes the wind turbine itself including support structures, the turbine controller, the charge controller / inverter (if required), wiring and disconnects, the installation and operation manual (s) and other documentation.While this standard is similar to IEC 61400-1, it does simplify and make significant changes in order to be applicable to small wind turbines. Any of the requirements of this standard may be altered if it can be suitably demonstrated that the safety of the turbine system is not compromised. This provision, however, does not apply to the classification and the associated definitions of external conditions in Clause 6. Compliance with this standard does not relieve any person, organisation, or corporation from the responsibility of observing other applicable regulations.This standard applies to wind turbines with a rotor swept area smaller than or equal to 200 m2, generating electricity at a voltage below 1 000 V a.c. or 1 500 V d.c. for both on-grid and off-grid applications.This standard should be used together with the appropriate IEC and ISO standards (see Clause 2).
