In this paper, the mathematical models including the line of DVR, the on-load tap-changer, the load and other related equipment are established, and the multi-time-scale characteristics of the system are pointed out. Integrating a fast process into a slow process using the integral flow pattern. The calculation example shows that this method can greatly improve the simulation efficiency under the premise of ensuring the analysis accuracy
