REM620C_F NCMNAAAAABC2BNN1XF  电机保护与控制

REM620是一个专用的电机lED完美对准的保护，控制。测量和监督中型和大型异步电动机，也需要差动保护，在制造和加工工业。REM620是ABB“Relion”保护和控制产品家族及其620系列的成员。620系列led的特点是其功能可扩展性和可取出单元设计。
620系列旨在释放lEC 61850标准的全部潜力，用于变电站自动化设备的通信和互操作性。

按钮和led可自由编程，可配置为操作和确认目的。这样，就有可能获得与按钮相关的已执行动作的知识。这种组合可以很有用，例如，快速选择或更改设置组，选择或操作设备，指示现场接触状态或指示或确认单个警报。
led也可以独立配置，以引起操作员注意的一般指示或重要警报。
为了提供按钮功能的描述，可以在按钮旁边的透明薄膜后面插入一张纸。

lED提供了大量的事件记录功能。普通用户可以使用PCM600中的事件查看器查看与流程相关的正常事件。关键系统和lED安全相关事件被记录到一个单独的非易失性审计跟踪中，供管理员使用。
审计跟踪是系统活动的时间顺序记录，允许构建和检查事件序列和事件中的变化。在PCM600中的事件列表和事件查看器的帮助下，可以以一致的方法检查和分析过去的用户和流程事件。lED将2048个系统事件存储到非易失性审计跟踪中。另外，1024个进程事件存储在一个非易失性事件列表中。审计跟踪和事件列表都根据FlFO原则工作。
用户审计跟踪是根据lEEE1686中选定的一组需求定义的。日志记录基于预定义的用户名或用户类别。用户审计跟踪事件在IEC 61850-8-1、PCM600、LHM和WHMI中得到支持。

lED支持一系列通信协议，包括lEC 6l850, IEC60870-5-103, Modbus*和DNP3。通过这些协议可以获得操作信息和控制。然而，一些通信功能，例如，led之间的水平通信，只能通过1ec 61850通信协议启用。
620系列led可以同时使用两种协议运行，其中一种协议始终是lEC6l850，另一种协议是基于订单码的任何其他可用协议(lEC 60870-5-103, Modbus或DNP3)。
lec6l850通信实现支持所有监控功能。此外，参数设置，干扰记录和故障记录可以使用lEC 61850协议访问。干扰记录可用于任何基于以太网的应用程序的标准COMTRADE文件格式。lED可以使用lEC61850-8-1 goose配置文件发送和接收来自其他lED的二进制信号(所谓的水平通信)，其中支持最高性能等级，总传输时间为3毫秒。此外，lED支持使用goosemessmessaging发送和接收模拟值。根据lEC 61850标准的定义，lED满足配电变电站跳闸应用的GOOSE性能要求。它可以同时向车站总线上的五个不同客户端报告事件。
lED可同时支持5个客户端。如果pcm600保留一个客户端连接，则只剩下四个客户端连接，例如lec6l850和modbus。
除前端口连接器外，所有通信连接器都放置在集成的可选通信模块上。lED可以连接到以太网-。基于RJ-45连接器(100Base-TX)或光纤LC连接器(100Base-FX)的通信系统。

REM620 is a dedicated motor lED perfectly aligned for the protection, control.measurement and supervision of medium-size and large asynchronous motors,requiring also differential protection, in the manufacturing and process industry.REM620 is a member of ABB’s Relion” protection and control product family andits 620 series. The 620 series lEDs are characterized by their functional scalabilityand withdrawable-unit design.
The 620 series has been designed to unleash the full potential of the lEC 61850standard for communication and interoperability of substation automation devices.

The buttons and LEDs are freely programmable, and they can be configured bothfor operation and acknowledgement purposes. That way, it is possible to getacknowledgements ofthe executed actions associated with the buttons. Thiscombination can be useful, for example, for quickly selecting or changing a settinggroup, selecting or operating equipment, indicating field contact status orindicating or acknowledging individual alarms.
The LEDs can also be independently configured to bring general indications orimportant alarms to the operator’s attention.
To provide a description of the button function, it is possible to insert a paper sheetbehind the transparent film next to the button.

The lED offers a large set of event-logging functions. Normal process-relatedevents can be viewed by the normal user with Event Viewer in PCM600. Criticalsystem and lED security-related events are logged to a separate nonvolatile audittrail for the administrator.
Audit trail is a chronological record of system activities that allows thereconstruction and examination of the sequence of events and changes in an event.Past user and process events can be examined and analyzed in a consistent methodwith the help of Event List and Event Viewer in PCM600. The lED stores 2048system events to the nonvolatile audit trail. Additionally, 1024 process events arestored in a nonvolatile event list. Both the audit trail and event list work accordingto the FlFO principle.
User audit trail is defined according to the selected set of requirements from lEEE1686. The logging is based on predefined usernames or user categories. The useraudit trail events are supported in IEC 61850-8-1, PCM600, LHM and WHMI.

The lED supports a range ofcommunication protocols including lEC 6l850, IEC60870-5-103, Modbus* and DNP3. Operational information and controls areavailable through these protocols. However, some communication finctionality,for example, horizontal communication between the lEDs, is only enabled by the1EC 61850 communication protocol.
The 620 series lEDs can run with two protocols simultaneously when one of theprotocols is always lEC6l850 and the other one is any of the other availableprotocols (lEC 60870-5-103, Modbus or DNP3) based on the order code.
The lEC 6l850 communication implementation supports all monitoring andcontrol functions. Additionally, parameter settings, disturbance recordings andfault records can be accessed using the lEC 61850 protocol. Disturbance recordingsare available to any Ethernet-based application in the standard COMTRADE fileformat. The lED can send and receive binary signals from other lEDs (so calledhorizontal communication)using the lEC61850-8-1 G0OSE profile, where thehighest performance class with a total transmission time of 3 ms is supported.Further, the lED supports sending and receiving of analog values using GOOSEmessaging. The lED meets the GOOSE perforance requirements for trippingapplications in distribution substations, as defined by the lEC 61850 standard. ThelED can simultaneously report events to five different clients on the station bus.
The lED can support five simultaneous clients. IfPCM600 reserves one clientconnection, only four client connections are left, for example, for lEC 6l850 andModbus.
All communication connectors, except for the front port connector, are placed onintegrated optional communication modules. The lED can be connected to Ethernet-.based communication systems via the RJ-45 connector (100Base-TX) or the fibre-optic LC connector(100Base-FX).
