TOPIC: WIND ENERGY
WIND ENERGY Energy of wind can be used for the generation of electrical energy. The potential of wind energy source of power is large. Wind energy which is an indirect source of energy can be utilized to run wind mill which in turn derive generator to produce electricity.
Characteristics of wind energy n n Wind power system is non-polluting. It is renewable source of energy. The energy generated by wind-power system is cheaper when produced on smaller scale. Wind energy system avoids fuel provision and transport.
Following problems are associated with wind energy n n n Wind energy is fluctuating in nature. Because of its irregularity it need storage device. There is sufficient noise produced by wind energy power generating system.
Wind mill n n Wind energy is used to run wind mill which in turn derives a generator to produce electricity. A wind mill converts the kinetic energy of moving air into mechanical motion that can be either Use directly to run the machine or to turn the generator to produce electricity.
Types of wind mills n Horizontal axis wind mills. • Multi blade type wind mill. • Sail type wind mill. • Propeller type wind mill. n Vertical axis wind mills. • • Savionius type wind mill. Darrieus type wind mill.
USES OF WIND POWER n n Cooling of homes. Space heating for operating irrigating. Navigational signals. Offshore drilling operations.
WIND TURBINE Wind energy conversion devices are commonly known as wind turbine because they convert the energy of wind stream into energy of rotation. ROTAR Component which rotates is called rotor.
DIFFERENCE BETWEEN VERTICAL AXIS WIND MILL AND HORIZENTAL AXIS WIND MILL. n n Vertical axis wind mill are of simple design as compared to the horizontal axis. Horizontal axis Wind mill may be single bladed, double bladed or multi bladed.
