Three-phase balance optimal design of power distribution for ship lightning system based on the improved simulated annealing algorithm

  Objectives  The three-phase balance optimization is of importance to the power distribution of ship lighting system design. For enhancing the design efficiency and accuracy, an optimal approach is presented based on a simulated annealing (SA) algorithm.

  Methods  Firstly, two optimal models are established for the upper-level distribution board and lower-level distribution box, respectively. Then, the SA algorithm is improved and applied to solve the problem of three-phase balance optimal design. Ultimately, a real case is tested based on the Matlab platform.

  Results  The test shows the presented approach can solve the three-phase balance of four power distribution boxes and one upper-level distribution board within one second.

  Conclusions  The presented approach can help relieve the excessive burden of three-phase load distribution for the lighting system by traditional design method and improve the design efficiency.
