ABB REG670 Integrated protection relay

The REG670 is used for protection, control and monitoring of generators and generatortransformer 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 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. The protection function library includes differential protection for generator, block, auxiliary transformer and the whole generator block. Stator earth fault protection, both traditional 95% protection as well as 100% 3rd harmonic based stator earth fault protection are included. The 100% protection uses a differential voltage approach giving high sensitivity and a high degree of security. 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. Serial data communication is via optical connections to ensure immunity against disturbances. The wide application flexibility makes this product an excellent choice for both new installations and the refurbishment of existing installations.
