Claim 2:
3. The energy storage transient power coordinated control method for restraining subsequent commutation failures of claim 2, characterized in that after the step S203, the step S2 further comprises:
S205: issuing the active power rising edge instruction and making a duration of the value PT of the output time instruction corresponding to the active output of an energy storage exceed an active time threshold when the DC current Idci exceeds the second current threshold IdrefL for the first time during a recovery process after a first commutation failure on the inverter side, so as to avoid short-term repeated trigger caused by high-frequency oscillation of the DC current near the second current threshold;
issuing the reactive power falling edge instruction and making the duration of the value QT of the output time instruction corresponding to the reactive output of an energy storage exceed a reactive power time threshold when the arc quenching angle is lower than the second arc quenching angle threshold for the first time during the recovery process after each commutation failure on the inverter side, so as to avoid short-term repeated triggers caused by high-frequency oscillation of the arc quenching angle near the second arc quenching angle threshold.
