标准摘要
[中文适用范围]： 本部分的 IEC 61850 定义了电力公用事业自动化通信和自动化IED（智能电子装置）及系统在发电厂和变电站环境中的通用要求，主要包括构造、设计和环境条件。这些通用要求与在类似环境中使用的IED（例如测量继电器和保护设备）的要求一致。当通信或自动化IED是发电厂或变电站中另一设备的组成部分时，该设备本身的环境要求适用于通信设备。 [外文原描述]： IEC 61850-3:2013 defines the general requirements, mainly regarding construction, design and environmental conditions for utility communication and automation IEDs (intelligent electronic devices) and systems in power plant and substation environments. These general requirements are in line with requirements for IEDs used in similar environments, for example measuring relays and protection equipment. This new edition includes the following significant technical changes with respect to the previous edition: - requirements are in line with those of other equipment used in the same environment (e.g. protection relays); - product safety added based on IEC 60255-27; - EMC requirements completed and in line with IEC 60255 series and IEC 61000-6-5.
