农村电气化用可再生能源和混合系统的建议.第6部分:验收、操作、维修和替换

[中文适用范围]： IEC 62257 的这一部分是一项技术规范，旨在描述适用于分散式农村电气化系统 (DRES) 的验收、操作、维护和更换 (AOMR) 的各种规则，这些系统旨在为以下场所提供电力：没有连接到大型互连系统或国家电网来满足基本需求。这些地点大部分是： 独立住宅；村屋；社区服务（公共照明、抽水、保健中心、礼拜或文化活动场所、行政大楼等）；经济活动（作坊、微型工业等）。本技术规范提出了一种方法，以实现设备的验收、运行、维护和更换以及整个系统生命周期的最佳技术和经济条件。它不能替代制造商为每台设备提供的技术手册。系统和应用程序的复杂性将决定所需的 AOMR 文档的级别。 [外文原描述]： IEC TS 62257-6:2015(E) describes the various rules to be applied for acceptance, operation, maintenance and replacement of decentralized rural electrification systems which are designed to supply electric power for sites which are not connected to a large interconnected system, or a national grid, in order to meet basic needs. This technical specification proposes a methodology to achieve the best technical and economic conditions for acceptance, operation, maintenance and replacement of equipment and complete system life cycle. The main technical changes with regard to the previous edition are as follows: - redefine the maximum AC voltage from 500 V to 1 000 V, the maximum DC voltage from 750 V to 1 500 V; - removal of the limitation of 100 kVA system size. This publication is to be read in conjunction with IEC 62257 series .
