☆型号：REG670 发电机保护 采用先进创新的滤波技术

【产品详情】

REG670 IED（智能电子设备）为水电站、抽水蓄能站、燃气站、联合循环站、蒸汽站和热电联产站中的发电机、原动机和升压变压器提供保护和监控。凭借出色的性能、灵活性和可扩展性，它满足了世界各个角落对新安装和改造的苛刻要求。

基于日立能源的丰富经验，REG670将发电机保护提升到一个新的性能水平。多达 24 个模拟输入允许将主保护和备用保护集成在一个 IED 中。或者，其他物体（如变压器）可以包含在发电机保护范围内。这样就可以完全复制主 1 和主 2 中的保护。这些功能可以减少保护整个发电站所需的简易爆炸装置数量，同时提高可用性。这反过来又简化了安装，并降低了与调试、维护和备件相关的生命周期成本。REG670功能还集成了智能故障标准，确保了无与伦比的选择性和灵敏度。

REG670采用先进创新的滤波技术，还可以为涡轮发电机提供集成的次同步谐振保护。

REG670的发电机保护方案满足了对最大可靠性和可用性的要求。发电机差动保护具有极快的检测标准，典型运行时间为 15 ms;同时保持高安全性。

在众多可用功能中，REG670 可以包括基于注入的 100% 定子和转子接地故障保护以及基于三次谐波的 100% 定子接地故障保护。这些解决方案提供了一种新方法，可以根据发电站的重要性或规模来优化保护系统的性价比。日立能源创新地实施了喷射原理，允许通过中性点VT甚至通过位于发电机端子的开三角VT进行喷射。由于无需对初级电路或接地电阻进行任何更改，因此保护系统的设计、安装和调试既简单又快捷。基于三次谐波的 100% 定子接地故障保护采用差分原理，提供高灵敏度和安全性。这确保了即使在低负载条件下也能正确运行。

【英文介绍】

The REG670 IED (Intelligent Electronics) protects and monitors generators, prime movers and boost transformers in hydroelectric, pumped storage, gas, combined cycle, steam and cogeneration stations. With outstanding performance, flexibility and scalability, it meets the demanding requirements for new installations and retrofits in all corners of the world.

Building on Hitachi Energy's extensive experience, the REG670 takes generator protection to a new level of performance. Up to 24 analog inputs allow primary and standby protection to be integrated in a single IED. Alternatively, other objects (such as transformers) can be included in the generator protection. This makes it possible to fully replicate the protection in master 1 and master 2. These features can reduce the number of IEDs needed to protect an entire power station while improving availability. This in turn simplifies installation and reduces life cycle costs associated with commissioning, maintenance and spare parts. The REG670 feature also integrates intelligent failure standards, ensuring unmatched selectivity and sensitivity.

The REG670 uses advanced and innovative filtering technology to also provide integrated sub-synchronous resonance protection for turbines and generators.

The REG670's generator protection solution meets the requirements for maximum reliability and availability. Generator differential protection has a very fast test standard, typical run time of 15 ms; While maintaining high security.

Among the many available features, the REG670 can include 100% injected stator and rotor ground fault protection and 100% stator ground fault protection based on third harmonics. These solutions offer a new way to optimize the cost performance of a protection system depending on the importance or size of the power station. Hitachi Energy has innovatively implemented the injection principle, allowing injection through the neutral point VT and even through the open triangle VT located at the generator terminal. Since no changes are required to the primary circuit or ground resistance, the design, installation and commissioning of the protection system is simple and fast. 100% stator ground fault protection based on third harmonic uses differential principle to provide high sensitivity and safety. This ensures correct operation even under low load conditions.

Relion - Totally confident
