Study of Lighter than air wind turbine systems and feasibility test of wind turbine before mounting it on an aerostat

摘要

Wind energy is the leading renewable source of energy. It can be used as most reliable alternative source of energy. Nowadays for producing electricity from renewable resources a new class of wind energy converters i.e. lighter-than-air wind turbine platform are being used. Buoyant airborne wind turbines are devices capable of harnessing stronger wind at higher altitudes. A wind-based power generating system provides a wind energy converter for converting wind energy into electrical energy using an aerostat. This paper encapsulates concepts that can be used in designing of turbine to enhance the power output. It reviews techniques used for wind profiling, aerostat lift calculation and theoretical power calculation of a given turbine. Various measures have also been discussed in detail, to eliminate risk that can occur when the aerostat is aloft. Tethering mechanism and attachment mentioned in this paper gives a brief idea about concept used for stabilizing aerostat. Materials which can elevate the performance of a given aerostat have also been elucidated further.
