Abstract

The invention discloses a low-voltage distribution network topology identification method based on unilateral optimization and genetic algorithm cooperation. The method comprises the following steps:reading electrical quantity data of distribution transformers and user ammeters in a distribution area, and screening and removing the electrical quantity data; determining an energy function taking the electrical quantity as a constraint; calculating a global optimal solution by adopting a genetic algorithm on the basis of the local optimal solution of the network topology; performing multi-section data sample verification and check based on a unilateral optimization construction method; and verifying the correctness, and outputting the topological connection relationship of a low-voltage distribution network under the condition that verification is correct. According to the invention, the low-voltage topological connection relationship of the transformer area is automatically inferred.

Description

technical field [0001] The invention relates to the technical field of distribution network topology identification, in particular to a low-voltage distribution network topology identification method based on cooperation of unilateral optimization and genetic algorithm. Background technique [0002] At present, there are mainly the following ways to distinguish the household-variable topology relationship in the low-voltage station area: [0003] 1. Line inspection method: For the power supply of users in the station area, the overhead line method is used. The traditional line inspection method starts from the outlet of the lower live wire of the user's meter box, traces the inspection line along the lower live line, and reaches the outlet end of the distribution transformer. Draw the wiring diagram and record the nameplate parameters and serial numbers of the equipment. The characteristics of this method are: heavy workload and low efficiency. Once the user changes the lin...
