| Abstract: | The substation is an important electrical device in the electrical system. The safe operation of the substation is directly related to the stable and safe work in the electrical system, so the acquirement of the substation protection reliability is extremely high. The substation served as the research object, the paper analyzes the large range differential protection fault action and find the reason of the substation differential protection fault action and presents the relevant countermeasures to improve the substation differential protection action. |
