Description
The 650 series IEDs include: • Customized versions providing the possibility toadapt the functionality to the application needs. • Configured solutions are completely ready to usesolutions optimized for a wide range ofapplications for generation, transmission and subtransmission grids. • Support for user-defined names in the locallanguage for signal and function engineering. • Minimized parameter settings based on defaultvalues and ABB's new global base value concept. You only need to set those parameters specific toyour own application, such as the line data. • GOOSE messaging for horizontal communication. • Extended HMI functionality with 15 dynamic threecolor-indication LEDs per page, on up to threepages, and configurable push-button shortcutsfor different actions. • Programmable LED text-based labels. • Settable 1A/5A -rated current inputs.
REC650 is used for the control, protection andmonitoring of different types of bays in powernetworks. The IED is especially suitable forapplications in control systems with distributedcontrol IEDs in all bays with high demands onreliability. It is suitable for the control of allapparatuses in single busbar single CB, doublebusbar single CB switchgear arrangement. The control is performed from remote (SCADA/Station) through the communication bus or fromlocal HMI. Different control configurations can beused, and one control IED per bay isrecommended. Interlocking modules are availablefor common types of switchgear arrangements. Thecontrol is based on the select before executeprinciple to give highest possible security. Asynchronism control function is available to interlockbreaker closing. A synchronizing function wherebreaker closes at the right instance in asynchronousnetworks is also provided. A number of protection functions are available forflexibility in use for different station types andbusbar arrangements. The auto-reclose includespriority circuits for single-breaker arrangements. Itco-operates with the synchronism check functionwith high-speed or delayed reclosing.
High set instantaneous phase and groundovercurrent, 4 step directional or non-directionaldelayed phase and ground overcurrent, thermaloverload and two step under- and overvoltagefunctions are examples of the available functionsallowing user to fulfill any application requirement. Disturbance recording is available to allowindependent post-fault analysis after primarydisturbances. Three packages have been defined for followingapplications: • Single breaker for single busbar (A01A) • Single breaker for double busbar (A02A) • Bus coupler for double busbar (A07A) The packages are configured and ready for directuse. Analog and control circuits have been predefined. Other signals need to be applied asrequired for each application. The main differencesbetween the packages above are the interlockingmodules and the number of apparatuses to control.
