Switchgear optimization using IEC 61850-9-2

This document describes the utilization of the nonconventional measurements and advanced features of IEC 61850 standard for substation automation systems, especially how sampled value sending according standard part 9-2 can be used between IEDs in medium-voltage substation to improve the reliability and functionality of the system. Calculated results indicate improvements on availability, performance and reliability with the selected application example, busbar voltage sharing.
