Siemens Distribution Feeder Automation

Siemens Distribution Feeder Automation (SDFA) is a feeder-based, distribution automation solution that improves distribution network reliability by employing self-healing, smart grid technology.





SDFA minimizes feeder down time by quickly and automatically restoring operation to serviceable feeder sections, while isolating those requiring repair. This results in minimal outage time, fewer service calls, and reduced monitoring and management demands.

Siemens vision was to create a peer-to-peer, model-based solution according to smart grid standards established by the Department of Energy (DOE) and the National Institute of Standards and Technology (NIST). SDFA was the result. In its simplest configuration, SDFA consists of two or more Automation Controllers and a high-speed, IP-based network that allows for IEC 61850 peer-to-peer communications between controllers. Optional system components include all types of switchgear, wireless communications system, and PC-based and substation-hardened Human Machine Interfaces (HMI).

Siemens offers SDFA as a drop-into-place, turnkey solution, including system design, supply, configuration and site testing. Siemens can also help utilities with the planning, design, supply, configuration and testing of your communications system.
