1. Introduction
The wind energy is an environment-friendly and efficient source of renewable energy. The kinetic energy of the wind can be used to do work. This energy is harnessed by windmill in the past to do mechanical work. This is used for water lifting pump and generating electricity. To generate the electricity, the rotary motion of, the windmill is used to turn the turbine of the electric generator. The output of single windmill is quite small and cannot be used for commercial purposes. Therefore, a number of windmills are erected over a large area, which is known as wind energy farm. The each and every windmill is coupled together to get a electricity for commercial purposes. The wind speed should be higher than 15 Km/hr.
2. Components of a Windmill Working System
2.1 Rotor Blades -
The blades are the most recognizable part of a windmill. They are usually made of fiberglass or wood and are designed to be aerodynamically efficient to capture the maximum amount of wind energy.
2.2 Rotor Hub -
The rotor hub is the central part of the windmill where the blades are attached. It is connected to the gearbox that converts the rotational motion of the rotor into electricity.
2.3 Gearbox -
The gearbox is a complex mechanical device that increases the rotational speed of the rotor and converts it into electricity.
2.4 Generator -
The generator is responsible for converting the mechanical energy from the gearbox into electrical energy. It consists of a rotor and a stator, with the rotor rotating inside the stator.
2.5 Tower -
The tower is the tall structure that supports the entire windmill. It is usually made of steel or concrete and is designed to withstand high winds and extreme weather conditions.
3. Materials and methods
3.1 Windmill using multi generator
The two electromagnetic induction generator are connected in both end of the shaft through coupling. The windmill rotor transmit the power to the two generator through straight bevel gear. The power output of multi- generator used windmill will be two times of single generator used windmill.
3.2 Principle of the methods
The windmill is works on the principle of generating power through the force of the nature (air). The blades of windmill are rotated due to the force of wind strikes them. The rotating blades are transmitting the power to the generator through the shaft and gear box and generate the electricity.
3.3 Construction of the methods
For Horizontal blade wind turbine, the main parts are follows below:
• Blades and rotor,
• Electromagnetic Induction Generator
• Gears (straight bevel gear mechanism),
• Shaft.
The blades are attached with rotor by using bolt and nut. The rotor connected with gear through shaft and balance by bearing. The gear box consists of driver and driven gear. The driven gear teeth are mesh with driver gear. The one end of the low speed shaft is connected with driver gear and other end is connected with rotor turbine of the windmill. The long high speed shaft is connected at the center of the driven gear. The both end of the shaft is connected with two same or different generator through coupling.
The blade is attached with rotor. The rotor connected with straight bevel gear through shaft. The gear box consists of driver and driven gear. The one end of the low speed shaft is connected with driver gear and other end is connected with rotor turbine of the windmill. The long high speed shaft is connected at the center of the driven gear. The both end of the shaft is connected with two same or different generator through coupling.
3.4 Poles of generator
The one of the Generator is rotated at clockwise and other one is rotated at anticlockwise. The anticlockwise rotating Generator is not giving the current. So, we change the poles inside the motor. The poles of two motor is parallel and connected with driven gear through long shaft.
3.5 Working of the Method
The rotor is rotated due to the force of wind strikes the blades of windmill. The rotating blades are transmitting the power to the gear box (driver gear) through rotor from the shaft. In gear box, the straight bevel gear mechanism is used which consist of driver and driven gears. The driver gear is transmitting power to the driven gear. Finally, the gear box is transmitting power to the two Generator through shaft in driven gear. The Generator shaft is rotated and same torque is produced. Because, torque is product of force and area so we balance the force and area the torque will be same. The Generator generates current.
4. Wind power Equation
The Wind power Equation is a mathematical formula that is used to calculate the amount of power that can be extracted from the wind. It takes into account several variables, including the density of the air, the wind speed, and the size of the rotor blades. The equation is as follows:
Power = 0.5 x Density x Area x Velocity^3
where:
- Power is the amount of power that can be extracted from the wind (in watts)
- Density is the density of the air (in kg/m^3)
- Area is the area swept by the rotor blades (in m^2)
- Velocity is the wind speed (in m/s)
- 4.1.1 Density -
- The density of the air is an important factor in the Win dpower Equation because it affects how much air the rotor blades can capture. Air density decreases as altitude increases and temperature rises, so wind turbines at higher altitudes or colder temperatures can produce more power.
- 4.1.2 Area -
- The area swept by the rotor blades is also a critical factor in the Wind power Equation. Larger blades can capture more wind energy, but they also require a stronger tower and foundation to support the extra weight.
- 4.1.3 Velocity -
- Wind speed is the most significant factor in the Wind power Equation, as it has the most significant impact on power production. As the wind speed increases, the power produced by the turbine increases exponentially. However, turbines are designed to operate within a specific wind speed range to prevent damage.
