标准摘要
[中文适用范围]: IEC 62257 的这一部分提供了一种方法,用于描述电气化系统要实现的结果,独立于可以实施的技术解决方案。 IEC 62257 这一部分的目的是提供一种方法,帮助项目承包商和项目开发商为隔离地点选择和设计电气化系统,同时满足已确定的需求,例如 IEC TS 62257-2 中描述的需求。 IEC TS 62257-2 评估用户的需求以及可用于满足这些需求的不同电源系统架构。针对项目不同参与者的需求,列出了生产和分配子系统应实现的功能要求。第 5 条描述了需要考虑的能源管理规则。这些都是关键问题,因为它们对电气化系统的规模有很大影响。在第 6 条中,列出了系统选型过程提供的信息,以允许参与者选择能够满足功能要求的设备或组件。为了允许和促进微型发电厂的管理和整个电气化系统的维护,需要收集和监控一些信息。第 7 章专门定义数据采集的参数和指定规则。 [外文原描述]: IEC TS 62257-4:2015(E) provides a method for describing the results to be achieved by the electrification system independently of the technical solutions that could be implemented. The purpose is to provide a method to assist project contractors and project developers to select and design the electrification system for isolated sites while matching the identified needs, such as those described in IEC TS 62257-2. 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 .
