Abstract
With the development of smart substation, information sharing and its redundant transmission of analog quantities in secondary system provide new research ideas for distributed state estimation of power system. This paper proposes distributed state estimation method based on information redundant of secondary system and gives its structure and content and builds a linear static model of distributed state estimation by using redundant relationship of analog quantities. Furthermore, a numerical example is designed to simulate and verify the proposed method. The experiment results show that the method can effectively reduce absolute error of analog quantities and improve uploading analog quantities reliability.关键词
