Abstract
A system for voltage signal distribution in a digital substation protection system. In a system where a voltage signal from a bus is not available, an alternative voltage secondary signal may be selected as a reference voltage and made available to the appropriate protection devices in a digital substation protection system for synchronism check. Voltage signals may be distributed using software-defined networking. A voltage selection controller may select the reference voltage and control distribution of the voltage signal using the software-defined networking communication system.
