Live replacement of transformers could realize a more convenient way for overhaul and maintenance for this importance equipment in distribution networks. However, a series of harmful impact of transient process may be introduced into the transformer itself and the power distribution system, which would affect accurate measurement and stable operation of the grid. A PSCAD-based simulation model of live replacement for transformers is presented in this paper, and the corresponding method of optimization is also proposed. The scheme presented here is proved to realize live replacement on site, which is significant for improving the level of live maintenance automation and reliability of power distribution systems.
