AI Technical Summary

Technical Problem

In existing offshore floating photovoltaic array designs, external wave protection/wave dissipation facilities are typically relied upon to reduce wave effects, resulting in high engineering construction and operation and maintenance costs, and failing to fully utilize the wave reflection and scattering potential of the array structure.

Method used

By arranging reflective unit groups around the outer periphery of the offshore photovoltaic array, and using the parameters of the cylindrical pontoon array to form a wave-reducing barrier, combined with the downsizing design of the internal unit groups, wave reflection and scattering are achieved, reducing wave transmission and lowering the structural strength requirements.

Benefits of technology

Without adding additional protective structures, the impact of waves on the array is reduced, material consumption and engineering costs are decreased, and the structural economy and feasibility are improved.

Abstract

This invention discloses a wave-reducing offshore photovoltaic array and its design method based on the wave reflection principle, belonging to the field of renewable energy development technology. The method involves setting a target wave period range; establishing a frequency domain hydrodynamic model of the cylindrical pontoon array; calculating wave transmission indices for different parameter combinations within the target wave period range; determining candidate parameter combinations based on these indices; establishing a structural finite element model of the reflection unit group based on the candidate parameter combinations and performing strength verification; establishing a coupled dynamic model of the array structure and mooring system; calculating the motion response and mooring forces; and making judgments based on preset criteria; and outputting the required reflection unit group pontoon array parameter combination. This invention solves the problem that existing offshore floating photovoltaic arrays rely on external wave protection / dissipation facilities to reduce wave effects, resulting in high engineering construction and operation and maintenance costs. Furthermore, it achieves internal wave load reduction and structural economic improvement within the array.
