Description

Fault on line side

The line protection IED detects a fault, issues a trip command to the CB and indicates the

issued trip on the station bus by GOOSE. The GOOSE DA is received by the REB500

Central unit.

The REB500 central unit forwards the information to the bay unit (see Table 10).

Due to the REB500 configuration (made with the HMI500 tool) the GOOSE data attributes

of the issued trip is mapped to the breaker failure start signal(s).

The bay unit starts the breaker failure protection

The circuit breaker fails to trip (trip issued by line protection IED à see "Step 2"

If circuit breaker tripping is not successful after BFP timers have passed:

· a remote tripping command is sent (via teleprotection)

· intertripping is sent to the central unit

The Central unit performs the intertripping to the respective bay units

The bay units of the respective zone issue a trip command and consequently clear the

fault

Interface to System engineering Tool

Using GOOSE input signals for protection functions requires interaction between

the REB500 configurator (HMI500) and the System engineering tool. Table 10

provides an overall view of the engineering process.
