Abstract
The invention discloses an energy storage transient power coordinated control method for restraining subsequent commutation failures, which includes: detecting DC current, AC bus voltage and arc quenching angle on the inverter side; Controlling the energy storage power station to enter the transient control mode when the DC current is greater than the first current threshold or the AC bus voltage is less than the voltage threshold or the arc quenching angle is less than the first arc quenching angle threshold. By detecting the DC current and arc quenching angle on the inverter side, the active power output time instruction and reactive power output time instruction are determined respectively. The active power output amplitude instruction is determined by detecting the AC bus voltage, and the reactive power output amplitude instruction is determined by using the constraint of the total energy storage capacity.
