产品详情
产品介绍详情:RET670 1MRK002246-BD 线路差动保护RED670 Relion®670系列
RED670 ied还可以在直接传输跳闸方案中提供额外的逻辑,以最大限度地减少由保护通信中的错误信号引起的不必要操作的风险。
在为特定应用程序配置逻辑时,可以使用几种不同的保护功能作为本地标准。
此外,线路差动保护功能提供了额外的本地标准,如相对相电流变化。这保证了在保护通信频繁失败导致数据丢失的情况下,IED能够正常工作。
从而维护了保护系统的安全性,降低了客户供电中断的风险。
快速高效的系统集成
RED670简易爆炸装置不仅仅是装置。它们利用ABB独特的连接包概念,简化了系统工程并降低了系统集成中的错误风险。这个包包含了一个完整的描述,具体的IED,包括数据信号,参数,地址和IED文件。
信号数据根据连接包提供的信息自动配置,从而有效地将ied集成到ABB的MicroSCADA Pro自动化系统中。
Relion®670系列简易爆炸装置支持站总线上的IEC 62439标准冗余通信。ABB的解决方案采用IEC 62439-3标准化并行冗余协议(PRP)。PRP提高了通信系统的可靠性,并具有在通信故障情况下零秒恢复的独特能力。这意味着,如果一个链路发生故障,由于另一个链路立即接管通信,通信将不会中断。因此,在发生通信故障时不会丢失数据。
RED670
RED670 IEDs can also provide additional logic in the direct transfer trip schemes to minimize the risk of unwanted operation caused by a false signal in protection communication.
Several different protection functions can be used as local criteria when configuring the logic for a specific application.
Furthermore, the line differential protection function offers additional local criteria, such as phase-to-phase current variation. This ensures correct operation of the IED in case data is lost due to frequent failures in protection communication.
Consequently, the protection system security is maintained, and the risk of interruption in electricity supply to customers is reduced.
Fast and efficient system integration
RED670 IEDs are more than just devices. They utilize ABB’s unique connectivity package concept, which simplifies the system engineering and reduces the risks of errors in system integration. This package contains a complete description of the specific IED, consisting of data signals, parameters, addresses and IED documentation.
The signal data is configured automatically based on the information provided by the connectivity package to efficiently integrate the IEDs in ABB’s MicroSCADA Pro automation system.
Relion® 670 series IEDs support IEC 62439 standard redundant communications on the station bus. The solution from ABB utilizes the IEC 62439-3 standardized Parallel Redundancy Protocol (PRP). PRP improves the communication system reliability and features a unique capability of zero seconds’ recovery time in case of communication failures. This means that there will be no interruption in communication if one link fails as the other link instantaneously takes over the communication. As a result, there is no data lost when communication failures have occurred.
