Optimal Configuration of Fault Indicator Based on Bacterial Foraging Algorithm in Distribution Network

Fault indicator (FI) plays a crucial rule in enhancing service reliability in distribution network. This device is helpful to quickly find the fault location. To realize the economic configuration of fault indicator, this paper proposes an objective function with the consideration of equipment investment costs, operation maintenance costs and interruption costs. This paper takes use of the bacterial foraging algorithm (BFA) to solve the objective function and analyzes the fault indicator configuration of a small-scale network and makes algorithm simulation. In view of the BFA existed in solving discrete domain by defining the evolution domain to determine the direction of bacteria to promote chemo taxis solution, which can make it to solve 0 similar to 1 programming problem well. The simulation results prove the effectiveness and scientificity of the scheme.
