Abstract

The invention discloses an intelligent distribution network distributed power supply restoration system. The system comprises a communication network module, wherein a distribution network module is electrically connected with the communication network module through N (N is greater than 2) STUs included in a STU module and an instruction is sent to the distribution network module through the STUmodule; a distribution network information module which includes network topology information, electrical quantity information and switch attribute information and executes the instruction sent by thecommunication network module through the STU; and a switch module which include a segment switch and contact switch, wherein te contact switch is used for dividing the distribution network into independent operation parts, and the contact switch is directly electrically connected to the non-fault power outage area to perform the closed operation to realize power supply restoration to the non-fault power outage area. Each STU can store its own information through its own terminal, and the STU can also store the terminal information of the adjacent STUs through upstream terminals or downstreamterminals in the storage terminals.

Description

technical field [0001] The invention relates to the technical field of power supply, in particular to a distributed power supply restoration system of an intelligent distribution network. Background technique [0002] The smart distribution network is a key component of the smart grid. Its power supply reliability directly reflects the power supply capacity to users. Failures will reduce the power supply reliability of the distribution network. After the distribution network fails, the power supply in the non-faulty power outage area must be restored as soon as possible. ; Distribution network power supply recovery means that after the fault is isolated, the power supply recovery strategy is obtained through calculation under the premise of satisfying the constraints, and then the corresponding contact switch or section switch in the power supply recovery strategy is closed or disconnected to quickly restore the load in the power outage area In the process of power supply, t...
