Cascading failures are the main reasons for large-scale blackouts. Therefore, the studies on cascading failure phenomena in a power system have very important significance for prevention of blackouts. According to the analysis of prevention and emergency control strategies for cascading failures, this paper discusses about the rationality of the index based prevention control strategies, and further proposes a prevention model based on index. Because the model relates to the analysis of the transfer of the power flow in the power grid, it would bring some difficulties to solve. So, this paper presents the solving process of the model in detail, and demonstrates it in 14-node system. The simulation results prove the validity of the model.
