Applied Research of a New Ttpe of Gauss Seidel Method in the Power Flow Computation of Power System

This paper mainly introduces a new type of Gauss Sidel method in the applied reasearch of power flow computation of power system.First,old and new Gauss Sidel method is deduced respectively based on detailed conventional.Expression forms of node voltage equation of new method vary from traditional method.Computational formula is much simpler and the number of iterative times may be decreased and then use the C＋＋programming language for Gauss-Seidel method for programming.Finally the proposed new high method is applied to instances of power flow calculation.Calculation results show that the number of the new method′s iterative times compared with traditional methods reduces by 30%,and the application range of the acceleration factor extends for a wider range.
