REC670 用于电网中不同类型的托架的控制、保护和监测

REC670用于电网中不同类型的托架的控制、保护和监测。简易爆炸装置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消息和垂直客户端-服务器MMS通信到本地站或远程SCADA操作员工作场所的全站联锁。这支持在所有机柜中使用分布式控制ied的架构，对可靠性要求很高。
通过内置的PRP特性获得冗余通信，该特性可用于星型或环总线架构。REC670可用于所有电压水平。适用于任何类型开关柜布置中所有设备的控制。
通过IEC 61850-8-1 Ed1或Ed2站通信或内置多显示本地HMI，从远程(SCADA/站)执行控制。实施网络安全措施，确保即使同时发生网络攻击，保护和控制功能也能安全自主运行。对于所有常见类型的开关柜布置，有不同的控制和联锁预配置。一个REC670控制IED可用于单仓或多仓应用。控制操作基于先选择后执行原则，以提供尽可能高的安全性。有同步检查功能，以协助zui佳断路器关闭在正确的实例在同步和异步网络。
许多保护功能可灵活地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功能，例如，多达6个瞬时相和接地过流功能，4步定向或非定向延迟相和接地过流功能，热过载和频率功能，两个2步欠压和过压功能，自动重合闸功能和几种不同的测量功能。这与每个馈线可以显示一个或多个页面的多显示本地HMI一起，允许使用REC670保护和控制变电站中多达六个托架。

The REC670 is used for the control, protection and monitoring of different types of brackets in the power grid. Improvised explosive devices are particularly suitable for applications in control systems where the REC670's IEC 61850-8-1 Ed 1 or Ed 2 station bus functions can be fully utilized. It is used for full-station interlocking via GOOSE messaging and vertical client-server MMS communication to local stations or remote SCADA operator workplaces. This supports an architecture that uses distributed control IEDs in the organic cabinet, with high reliability requirements.
Redundant communication is achieved through the built-in PRP feature, which can be used in star or ring bus architectures. The REC670 can be used at all voltage levels. Suitable for control of all equipment in any type of switchgear arrangement.
Control is performed from a remote (SCADA/ station) via IEC 61850-8-1 Ed1 or Ed2 station communication or built-in multi-display local HMI. Implement network security measures to ensure that protection and control functions operate safely and autonomously, even if simultaneous cyber attacks occur. For all common types of switchgear arrangements, there are different control and interlock preconfigurations. A REC670 control IED can be used for single or multi-bin applications. Control operations are based on the select-first, execute principle to provide the highest possible security. There is a sync check feature to assist in optimum circuit breaker closure in the right instance in both synchronous and asynchronous networks.
Many protection features are flexible for different station types and bus arrangements. To meet the user's application requirements, the REC670 features, for example, up to 6 instantaneous phase and ground overcurrent functions, 4 step directional or non-directional delay phase and ground overcurrent functions, thermal overload and frequency functions, two 2-step undervoltage and overvoltage functions, automatic reclosing functions and several different measurement functions. This, along with a multi-display local HMI where each feeder can display one or more pages, allows up to six bays in a substation to be protected and controlled using REC670.
