The substation automation system provides the customer with:
- Innovative and flexible migration concept for the stepwise modernization during continuous operation
- Compact and economical retrofit solution based on the IEC 61850 standard
- REC 670 bay control IED with multi-object technology and RTU 560 with integrated HMI for local operation
- Communication to the network control system via IEC 60870-5-104 protocol for reliable remote control and monitoring
The system configuration used is based on the RTU 560 as station unit as well as the bay control IEDs of the new IED 670 product family. Apart from the communication to the network control center, the RTU 560 assumes further central tasks within the station. A web-based local operator workplace is realized via its integrated HMI and allows local control and monitoring of the substation. In addition to the network connection of the new bay control IEDs via IEC 61850, it provides for the parallel integration of remaining parts of the station, e. g. the transformer tapchanger and Petersen coil controller. Within the compact and space-saving solution, each four switchgear bays are reliably controlled by one REC 670 bay control unit. For remote diagnosis and service purposes, a second Ethernet-based communication was established.
