Rapid distribution method for multiple fault first-aid repair tasks of distribution network

Abstract

The invention relates to a rapid distribution method for multiple fault first-aid repair tasks of a distribution network. The method comprises the following steps: 1) establishing a fault adjacent load live-line state matrix according to live-line states of adjacent load nodes at two ends of a fault in the distribution network; 2) establishing a fault adjacent matrix according to a connection relation between faults in the distribution network; 3) establishing a downstream fault state matrix according to the fault adjacent matrix obtained in the step 2); 4) establishing a fault adjacent state according to the fault adjacent load electrified state matrix and the downstream fault state matrix; and 5) classifying the faults based on the fault adjacent state, and automatically allocating first-aid repair tasks according to the fault types. Compared with the prior art, the invention has the advantages of reducing the solving complexity, greatly reducing the calculation amount and the like.

Description

technical field [0001] The invention relates to the technical field of distribution network fault emergency repair, in particular to a method for quickly allocating multiple fault emergency repair tasks of a distribution network. Background technique [0002] The network topology of modern distribution network is becoming more and more complex. Natural disasters or emergencies cause frequent faults in distribution network, and the power outage caused by the fault will seriously affect people's normal production and life. After a fault occurs, the elastic distribution network can restore power supply through reconstruction, distributed generation (Distributed Generation, DG), micro-grid, etc., but if the line, switch, transformer and other components fail, it is necessary to organize emergency repair personnel to repair them on site. Power supply, and the complexity of the distribution network structure, load and DG fluctuations, and randomness of faults bring certain difficu...

Problems solved by technology

For the distribution network with multiple faults, it is necessary to formulate a reasonable emergency repair task allocation plan under the condition of limited emergency repair resources and personnel. Most literatures use the discrete bacterial population chemotaxis algorithm (DBCC) to solve the emergency repair sequence. It is obtained only from the perspective of faults, that is, the relationship between the fault and the distribution network topology is not considered, and the quality of the emergency repair plan needs to be judged by the objective function. In the iterative process, each emergency repair plan needs to solve the objective function, and the amount of calculation is large.
