REG670 B30X00-B21H09-B1A2-E-B-KB-B-A4A5-E1AE1E1AA-D 发电机差动保护

REG670用于从相对较小的机组到最大的发电机组的发电机和发电机变压器块的保护，控制和监测。IED有一个全面的函数库，涵盖了大多数发电机应用的需求。大量可用的模拟输入，加上庞大的函数库，使许多功能集成在一个IED中。在典型的应用中，两个简易爆炸装置可以提供全部功能，也提供了高度的冗余。REG670也可用于并联电抗器的保护和控制。
定子接地故障保护，包括传统的95%和100%注入和三次谐波。采用注射式保护时，在所有工作模式下，包括星点在内的电机定子绕组100%受到保护。基于三次谐波的100%定子接地故障保护采用三次谐波差分电压原理。基于注入的100%定子接地故障保护，即使在机器静止状态下也可以运行。在IED中包含了极滑、欠激励、转子接地故障、负序电流保护等行之有效的算法。
REG670中的发电机差动保护适用于考虑长直流时间常数和短跳闸时间要求等因素的发电机应用。
由于许多保护功能可以作为多个实例使用，因此有可能在一个IED中保护多个对象。在对发电机具有主保护的同一简易爆炸装置中，可以对辅助电力变压器进行保护。因此，该概念实现了非常具有成本效益的解决方案。
REG670还实现了有价值的监控可能性，因为许多过程值可以转移到操作员HMI。
广泛的应用灵活性使该产品成为新安装和现有发电厂翻新的绝佳选择。

强制二进制输入和输出是测试变电站布线以及测试ied配置逻辑的方便方法。基本上，这意味着IED I/O模块(BOM, BIM, IOM和SOM)上的所有二进制输入和输出都可以强制为任意值。
中央帐户管理是一种身份验证基础设施，它为对变电站内的ied和其他系统实施访问控制提供了安全的解决方案。
这包括对用户帐户、角色和证书的管理，以及对用户完全透明的分发过程。
灵活的产品命名允许客户使用独立于IED供应商的IEC 61850型号的IED。该客户模型将在所有IEC 61850通信中公开，但IED的所有其他方面将保持不变(例如，本地HMI上的名称和工具中的名称)。这为使IED适应客户的系统和标准解决方案提供了极大的灵活性。

REG670

The REG670 is used for protection, control and monitoring of generators and generator-transformer blocks from relatively small units up to the largest generating units. The IED has a comprehensive function library, covering the requirements for most generator applications. The large number of analog inputs available enables, together with the large functional library, integration of many functions in one IED. In typical applications two IED units can provide total functionality, also providing a high degree of redundancy. REG670 can as well be used for protection and control of shunt reactors.
Stator earth fault protection, both traditional 95% as well as 100% injection and 3rd harmonic based are included. When the injection based protection is used, 100% of the machine stator winding, including the star point, is protected under all operating modes. The 3rd harmonic based 100% stator earth fault protection uses 3rd harmonic differential voltage principle. Injection based 100% stator earth fault protection can operate even when machine is at standstill. Well proven algorithms for pole slip, underexcitation, rotor earth fault, negative sequence current protections, and so on, are included in the IED.
The generator differential protection in the REG670 adapted to operate correctly for generator applications where factors as long DC time constants and requirement on short trip time have been considered.
As many of the protection functions can be used as multiple instances there are possibilities to protect more than one object in one IED. It is possible to have protection for an auxiliary power transformer integrated in the same IED having main protections for the generator. The concept thus enables very cost effective solutions.
The REG670 also enables valuable monitoring possibilities as many of the process values can be transferred to an operator HMI.
The wide application flexibility makes this product an excellent choice for both new installations and for refurbishment in existing power plants.

Forcing of binary inputs and outputs is a convenient way to test wiring in substations as well as testing configuration logic in the IEDs. Basically it means that all binary inputs and outputs on the IED I/O modules (BOM, BIM, IOM & SOM) can be forced to arbitrary values.
Central Account Management is an authentication infrastructure that offers a secure solution for enforcing access control to IEDs and other systems within a substation.
This incorporates management of user accounts, roles and certificates and the distribution of such, a procedure completely transparent to the user.
The Flexible Product Naming allows the customer to use an IED-vendor independent IEC 61850 model of the IED. This customer model will be exposed in all IEC 61850 communication, but all other aspects of the IED will remain unchanged (e.g., names on the local HMI and names in the tools). This offers significant flexibility to adapt the IED to the customers’ system and standard solution.
