The invention provides a scheduling system for the grid connection of multiple wind electric fields. The scheduling system comprises at least one scheduling center, a plurality of transformer stations, a plurality of wind electric field monitoring systems, and a plurality of wind electric field information acquiring terminal devices. Each wind electric field monitoring system communicates with the plurality of wind electric field information acquiring terminal devices of the same wind electric field. Each transformer station communicates with the plurality of wind electric field monitoring systems. Each wind electric field monitoring system communicates with the corresponding transformer station. Each scheduling center communicates with the plurality of transformer stations. Each transformer station communicates with the corresponding scheduling center.
