Traditional electric power network analysis doesn’t involve with the distribution of non-electric flows after the electric power network transmission .As a result, this paper expounds the basic calculation thoughts of power network composite flow state and proposes the corresponding calculation method. The bus model and bus-branch model between non-electric variables and electric quantities are established in this paper. According to the relation that the sum of non-electric flow in and out of each bus is equal, the equations of composite flow are established. After appropriate bus numbering, the equations are solved. The distribution state of non-electric flow after electric power network transmission is acquired. The correctness and feasibility of the model and solving method are proved by the example, and discusses the possible application of power composite flow state information.
