The present invention relates to a chain type converter-based power distribution network electric energy quality comprehensive control method and system. The method includes a system-level control strategy and a device-level control strategy, wherein the system-level control strategy realizes load reactive power, harmonic and unbalanced current detection, power distribution network PCC fundamental wave positive sequence voltage control, and power distribution network PCC fundamental wave negative sequence voltage control, and comprehensively generates chain type converter current control instruction signals, and the device-level control strategy realizes sub-module direct-current side capacitor voltage control of chain type converter control, realizes three-phase conversion chain current control of a chain type converter according to a current control instruction from the system level, and generates chain type converter switching tube duty cycle signals. With the method and system provided by the technical scheme provided by the invention adopted, electric energy quality problems such as harmonic, flicker and imbalance in a power distribution network can be comprehensively controlled.
