Abstract
In the past several decades, there were presented different innovative technologies rather than traditional wind turbines for renewable energy that uses wind kinetic energy and remains in the air through aerodynamic forces. Unlike wind turbines with towers, their systems operate in a flight, and they are connected to a foundation by a cable that either transmits the energy generated at the airfoil or transmits mechanical energy to the ground. Nowadays, there are several existing and developing technologies; however, each of them has limitations and challenges. This work will present an analysis of air floating design for electricity generation at high altitudes. It is a tethered wind turbine with a Balloon system, which has a simple controlling system, relatively higher efficiency, and low-cost technology. The concept of the design is to model the electricity generation device powered by clean renewable energy, mainly wind power. Base on the concept of kite or helium balloon to provide enough buoyancy to keep the device working at certain altitude. To increase the energy conversion efficiency and the feasibility of the device, it is mostly used in the country, open area. Despite high efficiency which needs further investigation, the designed device is moveable, pollution free and little space consumed.
Highlights
Wind power has an important place in the future of the generation of electricity
Before modeling a tethered wind turbine with balloon, there was conducted a literature review base on all different existing design related to different kinds of kites, balloons, and relative electricity generators, wind technology
They differ in relation to the type of wing, which can be rigid or flexible; as to the location of the electric generator, which can be on the ground or suspended in the air
Summary
Wind power has an important place in the future of the generation of electricity. by using wind turbines, we can face problems with potential safety hazards and environmental implications. Some of the examples can be kite or balloon power generation, flying electric generators, rotor kites [1]. They are a low-cost renewable energy technology with a low environmental impact. The aim of the paper is to model a theoretical part of a tethered wind turbine with a balloon for electricity generation by using suitable environmentally harmless and low-cost materials. The modeling concept is to use tethered to the ground wind turbine (rotor with a shaft) that is lifted to the air due to the connected balloon, which will be filled with helium. A wind driven rotor with blades is affixed to the shaft, thereby enabling the shaft to impart rotational motion into the ground supported generator via tethered transmission cable
