Zusammenfassung:	The invention discloses a direct current power transmission system commutation failure fault recovery method. The method comprises the following steps of step1, collecting the direct voltage and the direct current of a direct current power transmission system, and the alternating voltage of an alternating current power grid connected to a reverse converter station; step2, according to an analog quantity collected in step 1, determining whether the direct current power transmission system has a commutation failure fault; step3, If the commutation failure fault occurs, making a rectifier converter station increase a firing angle, and making the reverse converter station trip off a direct current circuit breaker, simultaneously using the commutation failure time accumulator of the reverse converter station to start carrying out timekeeping and accumulate commutation failure time; when waiting set time is up or the commutation failure fault disappears within a certain time, making the rectifier converter station
