Abstract: With the development of intelligent power systems, one click sequential control has become increasingly practical in substation switching operations. However, due to the fact that intelligent substation technology is still in the development stage and there are still a large number of conventional substations that have not undergone intelligent transformation. Currently, there are few substations using sequential control technology, and there is a lack of practical operation and management experience. This article studies and introduces the substation sequence control renovation plan and acceptance process, providing reference for the optimization of substation sequence control renovation and construction in the future.
