Construction of Wind Pressure Database for Variously Arranged Photovoltaic Arrays

Toshiba has developed a method to predict wind pressure distribution, which is expected to contribute to the construction of a reliable large-scale photovoltaic (PV) power generation plant that can withstand strong winds. This method can be applied to variously arranged PV arrays to realize cost-effective design of the array arrangement.

In order to design an array arrangement in a short period, a wind pressure distribution database has been constructed on the basis of precise computational fluid dynamics (CFD) analysis for several probable array arrangements. Through the selection and interpolation of pre-analysis results, the database makes it possible to obtain the wind pressure distribution of a specified array arrangement without the need for time-consuming and costly large-scale analysis.
