A path towards cost effective and future-proof solutions

A Whitepaper by Welotec:

Unlike renovating the entire secondary system of power substations, adding software defined functions save time and cost. Retrofitting the virtual Merging Unit running on a Substation Server offers an efficient future proof upgrade. Simply add a substation server, some sensors and the virtual Merging Unit application and get IEC61850 interoperability, advanced measurements, and a future proof platform for virtualized applications.
