a new protection standard for your valuable assets
REG 670 IED (Intelligent Electronic Device) provides protection and monitoring for generators, prime movers and step-up transformers in hydro-, pump-storage-, gas-, combined cycle-, steam- and cogeneration stations. With excellent performance, flexibility and scalability it fulfils the demanding requirements of every corner of the world for both new installations and retrofits.
Based on ABB's extensive experience, REG 670 takes generator protection to a new performance level. Up to 24 analog inputs permit integration of main and back-up protection in one IED. Alternatively, additional objects, such as transformers, can be included in the generator protection scope. This enables full duplication of the protection in main one and main two. All this reduces the number of IEDs needed to protect the entire generating station, increasing availability at the same time. This in turn simplifies the installation and reduces its lifecycle cost from commissioning to maintenance and spare parts. Its functions also incorporate intelligent fault criteria to ensure unrivalled selectivity and sensitivity.
A generator protection system with REG 670 meets the requirements for maximum dependability and availability. The generator differential protection features extremely fast detection criteria, with a typical operate time of 15 ms - and yet the IED maintains high security. The internal/external fault discriminator is based on negative sequence differential values, enabling a fast and selective decision to operate. The detection criteria can be used to create intelligent, application specific functions to enhance your protection system to meet very specific requirements, for instance, when the operating conditions of the plant change.
The IEDs are delivered pre-configured and type-tested for easy handling of products – from ordering, engineering and commissioning, to reliable operation. If needed, additional I/O boards, communication options or application functions can easily be added to meet the specific requirements of your generating station. Furthermore, several instances of protection functions are readily included in the REG 670 IEDs, and you only need to set parameters related to the power system objects during commissioning.
REG 670 belongs to ABB's 670 series of IEDs that provide outstanding protection, monitoring and control capabilities for all transmission applications. All products in 670 series are based on a common hardware platform and software library. This enables increased efficiency because there is a single common procedure of working with all the products, and the same tool is used for all setting, configuration and disturbance handling.
