In this paper, a blackout simulation model considering hidden failures and reclosing is proposed, which is more realistic than the previous model. The operation of reclosing devices, the synchronization control for reclosing in two-ended sources transmission lines and the interaction between reclosing and relay protection are simplified. Simulation results of IEEE39-bus test system are obtained to confirm the validity of the model. Compared with the blackout simulation model considering only the hidden failures of relay protection, it shows that the trip caused by the transient faults and hidden failures induced by transient faults can be corrected in this large-scale blackout simulation model. It also shows that with the increase of the probability of hidden failure, the failure rate of reclosing becomes an important factor affecting the system recovery.
