[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 threephase 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.
