The present invention relates to the field of UHV multi-terminal hybrid direct current transmission fault handling, in particular, to a fault exit method for a three-terminal hybrid direct current valve group when inter-station communication fails. After a valve group of the LCC station on the rectification side fails, it should be ensured that the constant power VSC station on the inverter side is out of service first, and the constant DC voltage VSC station on the inverter side is out of service last, so as to ensure that when each station exits, the DC The voltage can be kept stable, avoiding the oscillation of the DC system and the loss of stability of the DC system. In the case of communication failure between three terminal stations, when the valve group fails to exit, the corresponding station adopts the method of extreme outage, which can effectively prevent the non-faulty valve group from being activated again due to overvoltage after the faulty valve group is blocked. If the valve group of the LCC station is faulty, after the rectifier side is out of operation, the low-current blocking method can ensure that the constant DC power VSC station on the inverter side and the constant DC voltage VSC station on the inverter side are blocked successively, effectively preventing the VSC station from being out of control.
