The invention relates to an electronic circuit design technology, in particular to an active disturbance rejection based frequency control system and method for a wind power generator system. The system comprises an AGC (automatic gain control) system and a HVDC (high voltage direct current transmission) system, wherein the AGC system comprises an ACE module, an ADRC (active disturbance rejectioncontroller), a generator speed regulation system and a generator connected in sequence; the HVDC system comprises a rectifier, a direct current transmission system, an inverter and an alternating current system which are connected in sequence as well as an AFC controller connected with the rectifier; the rectifier is connected with the generator; the AFC controller is used for primary frequency modulation control of the wind power generator system; the ADRC is used for secondary frequency modulation control of the wind power generator system. The disturbance rejection capacity of the control system is better than that
