The invention relates to an automatic load distribution method for an intelligent transformer substation. The automatic load distribution method includes performing load flow calculation of the whole network according to network and load data acquired currently by the intelligent transformer substation of a power distribution network; by a reactive power optimization module, on given constraint conditions, solving the optimal solution of an objective function by a search algorithm to obtain schemes on in and out of a reactive power compensation device and transformer tap adjustment; by a power distribution network reconstruction module, on given constraint conditions, solving the optimal solution of the objective function by a virtual stream algorithm to obtain schemes on combined operation of states of network section switches and communication switches; by an interactive computation module, interacting the two sub problems including reactive power optimization and power distribution network reconstruction t
