高压开关设备和控制设备.第3部分:基于IEC 61850的数字界面

[中文适用范围]： IEC 62271的本部分适用于所有额定电压等级高于1 kV的高压开关设备和控制设备及其组件，并规定了与电力公用事业自动化其他部分进行数字通信的设备及其对测试的影响。这种用于数字通信的设备@取代金属并行布线@可以集成到高压开关设备@控制设备@及其组件@中，也可以是外部设备，以便使现有开关设备和控制设备及其组件符合以下标准： IEC 61850 系列。该国际标准是基于IEC 61850系列的产品标准。它涉及根据IEC 61850系列具有串行通信接口的开关设备和控制设备@及其组件的所有相关方面。它特别定义了： a) 从 IEC 61850 系列中选择由此类开关设备和控制设备@及其组件支持的信息模型； b) 开关设备和控制设备@及其组件支持的通信服务集的一致性等级； c) 由于串行通信接口而需要对开关设备和控制设备及其组件的型式和例行试验进行修改和扩展。该标准规定了高压开关设备@控制设备@及其组件@中使用的数字通信设备的要求以及相关的测试要求。 IEC 62271 系列的相关开关设备标准一般适用于本标准中描述的附加规范。注1：本标准旨在促进通信接口的互操作性。互换性超出了本标准@的范围，因为没有要求。互换性也不属于 IEC 61850 系列的范围。注 2：关于电力公用事业自动化通信以及相关术语@定义和模型@的介绍，请参阅 IEC 61850-1，它概述了 IEC 61850 系列的总体目标和要求。 IEC 61850-7-1 概述了建模技术。 [外文原描述]： IEC 62271-3:2015 is applicable to high-voltage switchgear and controlgear for all rated voltage levels above 1 kV and assemblies thereof and specifies equipment for digital communication with other parts of the power utility automation and its impact on testing. This equipment for digital communication, replacing metal parallel wiring, can be integrated into the high-voltage switchgear, controlgear, and assemblies thereof, or can be external equipment in order to provide compliance for existing switchgear and controlgear and assemblies thereof with the standards of the IEC 61850 series. This second edition cancels and replaces the first edition published in 2006. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) an update to the latest edition(s) of IEC 61850 series; (e.g. Annex B "LNs for sensors and monitoring" of edition 1 has been deleted since these LNs are now covered by standard IEC 61850-7-4:2010) b) an update of normative references; c) the minimum voltage range this standard refers to, was changed from 72,5 kV to above 1 kV; d) the description of performance tests and conformance tests became more specific; e) the new - informative - Annex C gives an example for performance type testing; f) 6.2.3 "transmission systems" as well as appropriate subclauses have been superseded by standard IEC TR 61850-90-4:2013; g) fibre optical connector type LC becomes only recommended type of fibre optic connector in accordance with IEC TR 61850-90-4:2013; h) electronic nameplates have been redefined as extension of LN XCBR and LN XSWI with data objects, reflecting required additional name plate information.
