A Convenient Power Flow Method for Ship's Shore Power Supplying Networks

摘要

This paper presents a novel power flow method based on the Modified Backward-Forward Sweep algorithm of radial Ship's Shore Power Supplying Networks without involving node number and special rules. This method makes full use of the structure characteristics of the radiation distribution network; through the establishment of loop chain and a directional node table, by using breadth-first to search node sequence of generated power flow calculation, using the linear trend equation iteration to get each node voltage, it does not require complex number of nodes and branch, does not need to form the node admittance matrix and triangular matrix, with simple input data format, rapid computing speed, less memory and good convergence. Finally, the model of power distribution system should be set up on MATLAB platform and realized by fast plural matrix operation function, a practical calculation example proved the effectiveness of the proposed algorithm.
