Development of power generating section of autonomous wind energy systems for regions of continental climate with low wind pressure

Abstract

This article describes a design option for an energy generating section of a multi-tiered type of a wind power installation with vertical axis of rotation, the design of which makes it possible to obtain the highest efficiency values relative to the known analogues with placement in areas of unstable-low wind pressure. The results of mathematical modeling and the principle of
operation of the tiers of elements of power generating section with the vertical axis of rotation both individually and in combination with each other forming a complete execution are considered. It is proposed to create a five-channel confused tier of concentration and reorientation of the air flow moving along the trajectory of 3-dimensional logarithmic spiral. The main and secondary acceleration zones with the placement of the power take-off unit and the dispersion zone of the spent air flow were designed. The total values of average coefficients of the acceleration of the air flow passing through the power generating section at different speeds of the incident flow are determined. The analyzed version of the design does not require orientation in wind and has the potential to stabilize oncoming air flow.
