Abstract Achieving the betterment which exceeds the size of the feasibility study without land acquisition and realizing the goal with safety and without power cut, are the difficulties of the main electrical connection betterment of a 220kV large open-type substation. In this article, by analysis of the betterment of a 220kV key substation which changed double-bus type connection to sectionalized double-bus type connection, we provide technical guidance to solve the problems and realize the goal.
