GEK-113032A W650 Wind Generator Protection System 5-815 SETTINGS 5.5 CONTROL ELEMENTS5Once the breaker is open, it waits for the time set in the Dead Time N setting, N being the number of the cycle inprogress. If during this waiting the breaker is closed or reclose initiation conditions are given, the recloser will go toLOCKOUT status by anomaly (AR LCK BY ANOMALY).Once the Dead Time has expired, in case the Conditions Permission setting is disabled, a closing command wouldbe produced. If the conditions permission setting is enabled, the system will wait for the conditions fixed in theconditions input (AR CONDS INPUT) configured at Setpoint > Relay Configuration > Protection Elements; if thewaiting period for the reclosing conditions signal activation exceeds the Hold Time, the autoreclose will go to Lockoutstatus by conditions (AR LCK BY CONDS).The autoreclose gives a Closing command and waits for the breaker to close. If the Fail to Close Time setting isexceeded, the autoreclose will go to lockout by failure of closing (AR LCK BY FAIL CLOSE).At this point, the diagram indicates that a reclosing cycle has been reached, and so the cycle counter is increased. In thistime, the period set in Reset Time starts to count. If during the set element reset time there is no autoreclose initiation, thecycle counter will reset to its initial value (1), and the autoreclose will return to the standby status (READY). If during theReset Time setting period, there is a new autoreclose initiation, the Reclose In Progress sequence will start again. If thisreclose is produced after the last configured cycle in the Maximum Number of Shots setting, the autorecloser will go toLockout by maximum number of shots (AR LCK BY SHOTS).AR LOCKOUTThis is a safety status, scheme lockout blocks all phases of the reclosing cycle, preventing automatic reclosure.From the out of service (AR DISABLE) and BLOCK statuses, the autoreclose will stay in LOCKOUT prior to going toREADY.From the RECLOSE IN PROGRESS status, the recloser will go to LOCKOUT status if any of the anomalies describedabove occur.To go from the LOCKOUT status to READY it is necessary that the breaker is closed and stays closed for preset time inReclaim Time setting.AR BLOCKThe BLOCK status is similar to the LOCKOUT status, as it guarantees that if the autoreclose is in Block, no breakerclose command will be produced, but the difference between them is that this Block status is reached by an externalaction. The autoreclose block can be configured by pulse or level signals. This configuration must be selected atSetpoint > Relay Configuration > Protection ElementsWhen the autoreclose block signal is deactivated, either by a level change in the set signal (in case of block by level) orby an Unblock pulse (in case of block by pulse), the block status is abandoned and the autoreclose returns to theLockout status.Configurable signals to block the autorecloser are described in section 5.5.4.3.
