电力自动化中的通信表示

[中文适用范围]： 本文件规定了电力公用事业自动化系统中设备测试和维护所需交换信息的表示结构。主要适用于在其通信流程中至少有一部分按照IEC 61850（所有部分）进行信息通信的通信设备。 包括以下通信设备： - 光学互感器； - 与IEC 61850流量相关的传统互感器； - 合并单元； - 独立合并单元； - 具有至少一个IEC 61850接口的保护、控制和测量设备； - 开关设备控制单元（断路器IED）； - 提供IEC 61850接口的开关设备； - IEC 61850时间同步设备； - IEC 61850网关（RTU）和站HMI； - 数字扰动记录器/数字故障记录器； - 具有至少一个IEC 61850接口的数字通信协议网关； - 使用专有协议与具有至少一个IEC 61850接口的设备通信的保护、控制和测量设备。 不包括以下通信设备、方案和协议： - IEC 61850以太网交换机和网络拓扑； - 具有至少一个IEC 61850接口的PMU相量测量单元； - 变电站间通信的完整路径； - 仅通过硬连线通信的功能； - 仅使用专有通信协议系统的功能； - 协议映射到XMPP（IEC 61850-8-2）。 本文件是电力公用事业自动化其他文档标准的补充，并基于IEC 61850通信在不同设备之间协调逻辑数据流结构的表示，以提供可适用于任何IEC 61850变电站的参考文档。 [外文原描述]： IEC TS 63266:2023 specifies a structure for representation of exchanged information that is essential for testing and maintenance of the devices in power utility automation systems. It is mainly intended to be applied to communication equipment that communicate information in accordance with IEC 61850 (all parts) in at least one part of their communication flow. The following communication equipment is included within the scope: – optical instrument transformer; – conventional instrument transformers related to IEC 61850 traffic; – merging unit; – stand-alone merging unit; – protection, control and measuring devices with at least one IEC 61850 interface; – switchgear control unit (breaker IED); – switchgear providing IEC 61850 interface; – IEC 61850 time synchronization device; – IEC 61850 gateway (RTU) and station HMI; – digital disturbance recorder / digital fault recorder; – digital communication protocol gateways with at least one IEC 61850 interface; – protection, control and measuring devices that utilise a proprietary protocol for communication with devices that have at least one IEC 61850 interface. The following communication equipment, scheme and protocols are excluded from the scope: – IEC 61850 Ethernet switches and network topology; – PMU phasor measurement unit with at least one IEC 61850 interface; – the full path of substation-to-substation communication; EXAMPLE 1: The description of R­GOOSE Publisher in substation A does not include the description of R GOOSE Subscriber in substation B. – functions with only hardwired communication, e.g. direct analogue copper wired connection; EXAMPLE 2: A current transformer connected to a protection relay with hardwired tripping of a circuit breaker. – functions using only proprietary communication protocol systems; EXAMPLE 3: A dedicated system for collecting disturbance recorder files with courier protocol or path from IEC 60870­5­103 to IEC 60870-5-101 will not be presented in this document. – protocol mappings to XMPP (IEC 61850-8-2). This document forms a supplement to other documentation standards in power utility automation. It also harmonizes the representation of the logical data flow structures based on IEC 61850 communication among different devices in order to provide a reference document that can be created for any IEC 61850 substation. This document focuses in principle on the visualization of the digital information exchanged between IEDs and control or measurement devices in a power utility automation system. The information visualization does not refer to any graphical modelling but to a tabular format of presentation. The data in tabular format can be used as a basis for other kinds of visual presentation outside the scope of this document. For representing all kinds of substation information, a single suitable tabular form is not possible to find. This document instead presents a limited number of high visual performance representation formats. Presentation formats described in this document provide interactive visualization that assists users in analysing data and identifying some important and essential information in a more efficient way.
