The invention discloses a rectangular coordinate Newton method load flow calculation method for a small-impedance-branch-containing power grid based on a compensation method. Before performing load flow calculation, a small-impedance branch is processed firstly; the small-impedance branch is changed into two series branches, wherein the impedance of one branch is z1 which is equal to r<ij>+j(x<ij>+x<c>) while the impedance of the other branch is z2 which is equal to -jx<c>, wherein x<c> is a normal electric reactance average value x<av> of an electric power system. One small-impedance branch is changed into two branches with relatively high impedance through series compensation, so that the convergence of load flow calculation can be improved. By adoption of the load flow calculation method, the small-impedance branch of any impedance can be calculated, or even a branch with zero impedance also can be calculated; the small-impedance branch data is processed before the load flow calculation is performed; and the data is preprocessed, so that a load flow calculation program is not changed, so that the rectangular coordinate Newton method load flow calculation method is particularly suitable for transforming an old load flow calculation program.
