The scale and structure of the power communication network are becoming increasingly large and complex, and the large-scale failure will lead to the interruption of related power business. If not repaired in time, it will produce incalculable economic losses and dangers. However, the large-scale communication network fault repair work requires a lot of manpower, material resources and time, and the repair resources cannot arrive at the recovery site at the same time. Study the effective repair strategy, so that the relatively optimal repair strategy can be obtained as soon as possible after the large-scale failure, so that the damaged power service can resume communication as soon as possible, and avoid more serious economic losses and dangers caused by the power communication network which cannot be repaired quickly. This paper studies the network fault recovery method, for how to quickly and effectively restore large-scale network failure after power communication network, the single stage and multiple stage and fast network fault recovery method, in order to realize the power communi- cation network after large-scale fault communication, quickly and effectively operate safely and stably. The main research contents of this paper are as follows: (1) the single-stage recovery method of large-scale network failure. When power communication network large-scale failure, due to provide less recovery resources, namely cannot immediately completely repair the damaged network, also cannot make all damaged power service restore commu- nication, in this case need to use limited recovery resources to selectively repair the fault link in the network, to maximize the number of damaged business restore communication. This paper mainly introduces the power grid scheduling automation often fault problems, such as communication channel error code, remote control remote adjustment, etc., at the same time for the fault problems strategy analysis, and effectively improve the ability and level of power grid dispatching automation, power grid scheduling to provide reliable and accurate information data.
