Abstract：
 The invention relates to an online incorporated method of a tide model of a multiregion electric network, which belongs to the electric power system dispatching automatic field. The invention comprises an upper level electric network dispatching center and a lower level electric network dispatching center, wherein, an internal electric network model and tide distribution are automatically generated in the region by utilizing state estimation method according to real-time data of the electric network under jurisdiction, and simultaneously an external electric network equivalent model connected with the internal network model is built up; lower level electric network models and tide data are sent to the upper level electric network dispatching center through the wide area network; upper level electric network models are connected with the lower level electric network models through respective connecting lines; the upper level electric network models and the lower level electric network models are incorporated into a global electric network model for counting; tide matching method is utilized to regulate the tide of the lower level electric network models, and a global electric network tide model is achieved. The method guarantees unchanged tide of intermediate and upper level electric network parts in the global electric network model after incorporation; the invention guarantees the accuracy of online safety analysis and simulation results of the interconnecting electric network, and is of great importance for guaranteeing safe operation of the electric network.
