The invention discloses an integrated offshore wind electric field fault ride-through method based on HVAC grid connected. The method comprises steps that 1), reactive demands under fault ride-throughconditions is calculated; 2), a reactive output limit of each set and a real-time reactive output limit of the whole offshore wind electric field set are calculated; 3), in a low voltage ride-throughcontrol mode, a dynamic reactive power compensator is cooperated by the wind electric field set to carry out layered capacitive reactive support; 4), in a low voltage ride-through continuity period,early removal of a crowbar circuit is considered, stator side reactive output capability of the set is recovered; 5), for the set of which a rotor transverter is under control and a reactive injectioncurrent can not satisfy requirements in the low voltage ride-through continuity period, through limiting output of active power, reactive output capability is enhanced; and 6), in a high voltage ride-through control mode, the dynamic reactive power compensator is cooperated by the wind electric field set to carry out layered sensitive reactive support. The method is advantaged in that offshore wind electric field fault ride-through capability is effectively improved.
