This detection method is combined with a two stage passive rate of change of frequency (ROCOF) observation.
If the ROCOF of the grid exceeds the configured disconnection threshold of stage 1 for the configured discon-
nection time, the device switches to zero current mode. If the ROCOF of the grid exceeds the configured dis-
connection threshold of stage 2 for the configured disconnection time, the device switches off. In case of an is-
land, this will shut down the island instantaneously. If the grid stabilizes, what might be the case if the ROCOF
event was due to a short disturbance in the power grid, the inverter will resume normal operation. With stage
1 active, the device has switched to zero current mode and will recommence feed-in after only 100 ms. With
stage 2 active, the device has switched off and the set reconnection conditions shall apply.
10.6 Behavior in case of communication failure
NOTE
Communication in the event of a communication timeout
In the event of a communication timeout, the value is queried in the timeout parameter for the reactive power
shift factor cos ϕ [See section 10.1.3
} Page 58] , reactive power [See section 10.1.3 } Page 58] and active
power [See section 10.2.2 } Page 61]. If all values for the timeout are set to 0 seconds, the current functions
are retained without a fault message being issued.
