Summary

The aeroelastic assessment of turbulence appearing in artificial boundary layers of photovoltaic power plants is treated in this paper. The approach suggested takes into account multiple functions in the analysis of skew flat plates of solar panels subjected to laminar and turbulent wind forces. Analysis and experimental assessments in the aerodynamic tunnel are presented. Some results obtained are discussed.

The topic of thepaper is the assessment of ultimate aeroelastic behaviour of skew plates of solar panels in photovoltaic power plants subjected to the laminar and turbulent forcing of the wind. The skew flat plates of solar panels are supported by metal structures anchored into the terrain. The panels create the active fields of the power plants. The photovoltaic power plants are located in territories where the wind loads represent the dominant environmental forces. The forcing is to be unified into maximal design values for a given territory. All structural elements are to be designed in accordance with valid standards and their aeroelastic assessments are required, for example, as a result of the recommendations in [1].

As a result of the small height of solar panels above the ground cataract air flows occur on the edges of the flat plates which increase the wind speeds and pressures. Regarding the variability of configurations of the photovoltaic power plants with artificial boundary layers at small heights, there turbulent wind flows are measurable only in the wind tunnel. The measurements in aerodynamic tunnels provide the data required for the analysis of the problem. The results obtained are discussed in the paper.
