Description

Technical Field

[0001] The present invention relates to the technical field of offshore new energy equipment, and in particular to a dynamic response control and vibration reduction system and method for a floating photovoltaic platform. Background Art

[0002] With the global development of clean energy technologies, offshore floating photovoltaics, a key application area following land-based photovoltaics and inland lake floating photovoltaics, are being gradually deployed in nearshore and deep-sea areas due to their advantages such as not occupying land resources, strong environmental adaptability, and stable energy access. However, compared with land and still waters, offshore floating photovoltaic platforms face more severe marine environmental loads, including the long-term coupling of complex operating conditions such as waves, wind, and tidal currents. This results in more significant structural dynamic response, making photovoltaic modules, cables, and connecting components susceptible to fatigue failure, seriously affecting the overall safety and service life of the system.

[0003] In existing technologies, passive responses to wave loads are primarily achieved by optimizing the layout of the floating structure, increasing the free plate height, increasing the ballast mass, or employing damping panels. However, these passive wave-resistance measures place high demands on the platform's gross weight, construction cost, and spatial layout, and are unable to adjust transient responses in real time to varying sea conditions. Consequently, issues such as over-response, localized damage, and increased fatigue damage persist, making it difficult to meet the demands for long-term stable platform operation in multi-source composite applications such as wind, solar, and tide.

[0004] Although some recent studies have proposed using ballast tanks, flexible connection structures, or attitude adjustment systems to adjust platform responses, most of these systems still rely on static or fixed-value configurations, lacking sea state perception, response identification, and adaptive control capabilities. Consequently, an integrated, intelligent dynamic response control system has yet to be developed. Therefore, there is an urgent need for a control system that integrates multi-source information perception, response modeling and identification, and dynamic execution control. This system can intelligently adjust the platform's structural state based on actual operating conditions, significantly improving its adaptability to wave disturbances and enabling safe, stable, and long-term operation of offshore floating photovoltaic platforms in complex sea conditions. Summary of the Invention

[0005] The purpose of the present invention is to overcome the problems of existing offshore floating photovoltaic platforms under complex sea conditions, such as violent structural response, frequent component fatigue failure, and lack of dynamic control means. It provides a dynamic response control and vibration reduction system and method for floating photovoltaic platforms, which can realize real-time perception of the platform's motion state, accurate identification of structural response, and active optimization and adjustment of wave resistance performance, thereby improving the system's operational stability and overall reliability.
