| Abstract: | The signaling-transmit and signaling-stop of high frequency blocking protection is the main factor to determining the proper action of the protection. The signaling-transmit circuit of high frequency blocking protection is comparatively simpler than signaling-stop circuit. The signaling-stop criterions of high frequency protection position signaling-stop, lines protection trip signaling-stop, busbar differential protection signaling-stop, failure protection operation signaling-stop and weak-infeed protection function have been presented. The problems should be noticed bin high frequency protection signaling-stop circuit have been summarized. |
