Fault recovery method applied to intelligent distribution network and based on load balance

The invention discloses a fault recovery method applied to an intelligent distribution network and based on load balance, which includes the following steps: 1, one intelligent distribution terminal is respectively installed at the position of each switch of the intelligent distribution network, each intelligent distribution terminal is regarded as an Agent, and all the Agents are connected with each other through the optical Ethernet network, 2, each Agent automatically determines a fault zone, a non-fault zone and a fault recovery zone through information interaction; 3, the fault of the agent at the position of each interconnection switch is recovered; 4, all the Agents perform information interaction to judge whether a load shedding zone exists, if the load shedding zone exists, the step 5 is carried out; otherwise, a fault recovery task is completed; 5, the Agent in the load shedding zone searches whether a DG capable of achieving plan islet operation exists in the load shedding zone, if exists, power supply recovery commands are sent to the Agent at the position of a DG outlet; otherwise, a load at the zone is removed from the distribution network; and 6, the Agent at the position of the DG capable of achieving the plan islet operation recovers power supply for a load at the zone according to the fault recovery method in the step 3, and the load which fails to be recovered is removed from the distribution network.
