Why to automate power substation? What do you get? | EEP

Integrated Protection Functions: Traditional Approach and Ied-Based ApproachAutomation FunctionsEnterprise-Level Application FunctionsIn the traditional approach, the relays had hardwired inputs from the instrument transformers, and from the relays, hardwires carried the trip signals to the circuit breakers, as shown in Figure 1. In the IED-based modern approach, the information from instrument transformers will reach the relay IEDs via LAN, the relays exchange information via LAN, and with the process bus becoming a reality, the circuit breakers will receive a trip signals via a generic object-oriented substation event (GOOSE) messagetraveling in the process bus, as illustrated in Figure 1b. In case of a breaker failure, in the traditional protection wiring scheme, the hardwiring will carry the trip signal to the backup protection scheme, as shown in Figure 2a. Protection functions like automatic reclosingand bus differential schemes can be implemented, and breaker failure can be dealt with effectively. Go back to contents ↑Get price
