Abstract BATS are very important for power distribution reliability. However, BATS can’t consider whether it cause overloading of devices after it acts. In this paper, we propose an optimal strategy of on-line strap controlling considering the characteristics of power grid. This method controls the running state of BATS by strap-controlling. Oil temperature and initial load ratio of transformer are considered in this method, N minus one is also taken into account. Time characteristics and split characteristics are considered in the model of BATS. Site operation shows that the proposed method is feasible and it can ensure power distribution reliability.
