RESUMO:

Arc flash is one of the most hazardous phenomena in industrial electrical installations, capable of releasing high amounts of energy within milliseconds, resulting in severe human and material damage. Mitigating this risk depends directly on reducing the total protection response time, from fault detection to the circuit breaker trip command. Traditionally, arc flash protection is performed by specific devices that detect intense light emission and abrupt current increases, characteristic of short circuits, ensuring fault clearing times significantly shorter than those of conventional overcurrent relays. In industrial substations, typically fed by a main substation, a vulnerability is observed in arc flash protection at the cable entry region of the main panel, since the upstream circuit breaker responsible for fault interruption is often located kilometers away, making rapid and effective response by conventional protection systems difficult. In this context, this work aims to define a methodology for reducing the incident energy level in industrial substations through the use of the IEC 61850 communication standard, employing GOOSE (Generic Object Oriented Substation Event) messages to transfer the TRIP signal between substations. The experiments were conducted on a test bench, encompassing two test models: the first compared the performance of two arc flash detection and protection devices, while the second applied the best-performing configuration in three distinct arrangements of IEDs interconnected via an industrial switch, simulating the TRIP signal transfer via GOOSE messages. Preliminary results showed that arc protection relays achieved the shortest response times and, when combined with the most efficient GOOSE communication arrangement, provided faster response times than those typically applied in overcurrent protection schemes for industrial substation feeders. These results confirm the technical feasibility of using GOOSE communication in arc flash protection schemes, demonstrating a significant reduction in protection response time. Furthermore, the GOOSE protocol offers additional advantages, such as the ability to monitor the integrity of communication between devices, enabling continuous connection monitoring and alarm triggering in case of failures. This functionality directly contributes to the advancement of protection engineering practices by offering greater reliability and operational safety in industrial substations.
