The invention discloses a grid structure optimization method for realizing reliable splitting based on node relevancy. According to the method, aiming at the problem that a splitting strategy is not converged due to the fact that a grouping mode is not remarkable and a splitting range is widely distributed in the current splitting process, the association degree between system nodes is changed byadopting a method of adjusting the number of lines, so that the purpose of reducing a splitting decision space is achieved. According to the invention, generalized characteristic analysis is carried out based on a slow homology theory, and a dominant mode is acquired to construct a modal matrix; a slow homology matrix is acquired through Gauss elimination of principal elements; a node classification criterion is improved, and a node relevancy model is constructed; system stability constraint conditions are comprehensively considered, and a DPSO intelligent optimization algorithm is utilized toobtain an optimization sc
