Now considering the 6 m/s rotor torque curve and the medium load curve. When the stationary rotor is subjected to a 6 m/s wind speed, the rotor rpm will accelerate from zero to the rpm of the intersection between two curves and stabilize there. The rotor will produce torque following the 6m/s curve until the rotor torque balances with load torque at the intersection. So by plotting the, rotor torque curve for various speeds, the intersection of these curves will form the actual operating rpm of the wind turbine at various wind speed. However the rotor/load torque at different wind speed is not the actual power output, the actual output will be lower due to losses in the generator mechanical components and conversion losses.
Fig 3.3 shows another 2 load which is a light and heavy load A light load will cause rotor to operate at high rpm (high tsr) which will not maximize the rotor efficiency while the heavy load causes the rotor to rotate slowly (low tsr) which also do not maximize the rotor efficiency. By selecting a load nearer to the rotor maximum efficiency point like the medium curve more power can be obtained.

And it is because of the search for another means of power generation that necessitated the development of wind turbine.The wind energy is abundant in several parts. Among the numerous natural energy resources that Nigeria was blessed with, wind is among the once in great quantity.

CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONE1.0 INTRODUCTIONSince ancient times, people have harnessed the winds and energy. Over 5,000 years ago, the ancient Egyptians used wind to sail ships on the Nile River. Later, people built wind mills to grind wheat and other grains. The earliest known wind mills were in Persia. These early wind mills looked like large paddle wheels. Centuries later, the basic design of the wind mills was improved. It was given a propeller type blade. The evolution has been slow but continuous, wi ... Continue reading---
CHAPTER TWO - [ Total Page(s): 3 ]CHAPTER TWO2.0 CONSIDERATION FOR WIND POWERED GENERATORIn the 1970s, oil shortage pushed the development of alternative energy source. In 1990s, the push came from a renewed concern for the environment in response to scientific studies indicating potential changes to the global climate if the use of fossils fuels continuous to increase. Wind is a clean fuel; wind farms produce no air or water pollution because no fuel is burnt.Providing new cost effective advanced and innovative technologi ... Continue reading---
CHAPTER FOUR - [ Total Page(s): 4 ]Improvement in the design of VSCF machine has led to the development of special type called the “Double Output Induction Generator†(DOIG). In this, the solid state handling only the slip power and this seems an interesting comparism between the VSCF and CSCF Systems.The solid state electronics is used for rectification and the line commutator inverter inverts the slip power back to alternating current. Another version of the VSCF system has power output at modulated frequency higher ... Continue reading---
CHAPTER FIVE - [ Total Page(s): 3 ]5.3 ADVANTAGESThe advantages that wind power generation gives are enormousi) It relies on the renewable power of the wind which can’t be used up. That is it is fueled by wind.ii) These sources do not use burning fuel thus avoiding the inconveniences of supply and the dangers that arise through their storage.iii) Wind energy turbine doesn’t pollute the air like power plants that rely on combustion of fossil fuel such as coal or natural gas which when burnt go ...

CHAPTER SIX - [ Total Page(s): 1 ]CHAPTER SIXCONCLUSIONAs the need to stabilize the nation’s energy resource and electricity demands, renewable energy comes into play and also at a time when customers across the country are facing electricity rate hikes due to supply shortage, wind power is an attractive option to consumers and business alike.Wind energy works because it generates energy without fuel. While providing a reliable edge against rising energy cost. Wind energy works because the wind energy industry is a good s ... Continue reading---
