Siemens Smart Infrastructure has launched Siprotec V, a virtualised protection and control product for digital substations that runs on a server and replaces multiple dedicated devices.
Siemens positions the software-defined approach as a way for utilities and grid operators to reduce equipment in substations and standardise deployment across sites. Siprotec V is based on the Siprotec 5 protection and control range, which Siemens supplies as hardware devices for substations.
According to Siemens, Siprotec V can consolidate the functionality of up to 60 hardware-based Siprotec 5 devices into a single server-based implementation. That can reduce the number of protection and control panels required in a substation and cut capital expenditure by up to 25%.
Siemens also cited a reduction in building space, saying substation space usage can fall by up to 45% when utilities centralise protection and control functions in the server-based format.
