Summary:At present, developed cities such as Shanghai and Beijing, chain structure is mostly used in 110kV grids. There is a controversy for the implementation of the self-healing system and the PT layout scheme. By analyzing the role of self-healing system and its action logic, this paper gives the role of voltage value in the self-healing system. By comparing the reliability, floor area and investment of various PT arrangements, this paper proposes a PT setting recommendation plan, and analyzes the feasibility of the plan.
