System splitting problem (SS problem) is to determine proper points (or called strategies) split the entire interconnected transmission network into islands ensuring generation/load balance and satisfaction of capacity constraints when islanding operation a system unavoidable. For large-scale power system, its SS very complicated in general because combinatorial explosion strategy space happens. This paper mainly studies how find strategies systems using an ordered binary decision diagrams (OBDD)-based three-phase method. Then, time-based layered structure solving process introduced make this method more practical. Simulation results on IEEE 30- 118-bus networks show that by method, can be given quickly. Further analyses indicate effective for larger-scale systems.
