The invention provides a partition setting control method aiming at a large-scale wind electricity supply base. According to the method, all wind electricity fields are partitioned according to different belonging regions, on the basis of adopting the partition division according to the regions, the machine unit volume to be cut can be calculated in real time, the intelligent selective cutting of a wind electricity machine unit is carried out, and the machine units are selectively cut in an intelligent way in the cutting requiring regions, and the method realizes the effects that the requirement of solving the system stability problem can be sufficiently met, the effectiveness, the economy and the fairness of the machine cutting effects can be sufficiently embodied, and in addition, the fixed planting fixing requirements can be simplified. The control method has the advantages that the actual problems met in a wind electricity access electric network can be perfectly solved, and the stability of the electric network after the wind electricity access and the operation economy of an electric power system can be improved.
