详细介绍


REC670 1MRK002814-AB   间隔控制

1.应用程序REC670用于控制、保护和监测电网中不同类型的间隔。IED特别适用于控制系统中的应用,其中可以充分利用REC670的IEC 61850–8–1 Ed 1或Ed 2站总线功能。它用于通过GOOSE消息和与本地站或远程SCADA操作员工作场所的垂直客户端服务器MMS通信进行全站联锁。这支持了在所有机架中具有分布式控制IED的体系结构,对可靠性有很高的要求。冗余通信是通过内置的PRP功能获得的,该功能可用于星形或环形总线架构。REC670可用于所有电压电平。它适用于控制任何类型的开关设备中的所有设备。通过IEC 61850–8–1 Ed1或Ed2站点通信或通过内置的多显示器本地HMI从远程(SCADA/站点)执行控制。实施网络安全措施是为了确保保护和控制功能的安全自主运行,即使同时发生网络攻击。对于所有常见类型的开关设备布置,有不同的控制和联锁预配置。一个REC670控制IED可用于单隔间或多隔间应用。控制操作基于先选择后执行的原则,以提供尽可能高的安全性。在同步和异步网络中,有同步检查功能可帮助在正确的情况下优化断路器闭合。有许多保护功能可供灵活使用,适用于不同的站类型和母线布置。为了满足用户的应用要求,REC670具有多达六种瞬时相位和接地过电流功能、4步定向或非定向延迟相位和接地过电流功能,热过载和频率功能,两种2步欠压和过电压功能,自动重合闸功能和几种不同的测量功能。这与可显示每个馈线一个或多个页面的多显示器本地HMI一起,允许使用REC670对变电站中多六个隔间进行保护和控制。

1. Application REC670 is used for the control, protection and monitoring of different types of bays in power networks. The IED is especially suitable for applications in control systems where the IEC 61850–8–1 Ed 1 or Ed 2 station bus features of the REC670 can be fully utilized. It is used for station-wide interlocking via GOOSE messages and vertical client-server MMS communication to a local station or remote SCADA operator workplace. This supports the architecture with distributed control IEDs in all bays with high demands on reliability. Redundant communication is obtained through the built-in PRP feature which can be used in star or ringbus architectures. REC670 can be used on all voltage levels. It is suitable for the control of all apparatuses in any type of switchgear arrangement. The control is performed from remote (SCADA/Station) through the IEC 61850–8–1 Ed1 or Ed2 station communication or from the built-in multi-display local HMI. Cyber security measures are implemented to secure safe autonomous operation of the protection and control functions even if simultaneous cyber attacks occur. For all common types of switchgear arrangements, there are different pre-configurations for control and interlocking. One REC670 control IED can be used for single bay or multi-bay applications. The control operation is based on the select-before-execute principle to give highest possible security. There are synchrocheck functions available to assist optimal breaker closing at the right instance in synchronous as well as asynchronous networks. A number of protection functions are available for flexibility in use for different station types and busbar arrangements. To fulfil the user's application requirements, the REC670 features, for example, up to six instantaneous phase and earth overcurrent functions, 4–step directional or non-directional delayed-phase and earth overcurrent functions, thermal overload and frequency functions, two instances of 2–step under- and overvoltage functions, autorecloser functions and several different measuring functions. This, together with the multi-display local HMI that can show one or more pages per feeder allows using the REC670 for protection and control for up to six bays in a substation.
