Optimal Structural Design for Floating-Plants of Tidal Power Stations

An optimal structural model for floating plants of tidal power stations is developed. Based on the knowledge base of floating structure stability, the optimal design is performed by use of the mixing penalty function method, in which step optimization is combined with integral optimization, and the variable scale method is adopted for unconstrained minimization. Then a program of optimal structural design for tidal power stations is worked out. The stability and convergence of the computation results show that the optimal design is feasible.
