Description
Summary:The scheme of secondary equipment outdoor layout in smart substation has become the development trend in constructing smart substation. In this study, some schemes about outdoor layout relay protection in smart substation using electronic transformer are provided and compared, which is mainly focused on technical ideas, implementation plan and their advantages and disadvantages in engineering application. In addition, aiming at the problem of changing in testing, operation and maintenance work under this new mode, the authors provide a brief introduction on assembly line automatically closed-loop test technology of outdoor layout, miniaturisation relay protection equipment. The research results have been initially applied in design, test, operation and maintenance work in smart substation.
