The invention discloses a static synchronous compensator optimal configuration method and system. The method comprises the following steps: utilizing a secondary commutation failure judgment method toscreen out faults that can cause the secondary commutation failure from a fault set; A static synchronous compensator with different capacity is installed on the commutating bus of each inverter station, calculating the decrease of the secondary commutation failure severity of each fault after the static synchronous compensator with different capacities is installed on the commutation bus of eachinverter station, and performing fitting processing on the capacity of the corresponding static synchronous compensator to obtain a fitting relationship; Finally, according to the constraint conditions determined by the fitting relationship and the established optimization objective function, the capacity of the static synchronous compensator on the commutator bus of each inverter station is optimized. The invention optim
