LESSON 27. Wind energy conversion principles. The power in the wind. The wind systems that exist over the earth''s surface are a result of variations in air pressure.These are in turn due to the variations in solar heating. Warm air rises and cooler air rushesin to take its place. Wind is merely the movement of air from one place to another.

Working principle of a horizontal axis wind turbine. In a wind power plant, the kinetic energy of the flowing air mass is transformed into mechanical energy of the blades of the rotor. A gearbox is used in a connection between a low speed rotor and the generator. The generator transforms mechanical energy into electrical energy.

The total wind power is equal to the incoming kinetic energy of the wind stream. It can be expressed as: Total wind power, Pt = (ρACi3)/2. Where, ρ = density of air (in kg/m 3 ); A = rotor swept area = πr 2 (r = radius of blades in meters); C i = incoming wind velocity (in m/s). The density of air (ρ) is somewhat complicated since it

Direct energy conversion involves transforming one form of energy directly into another without intermediate steps. This includes solar cells, fuel cells, and thermoelectric generators. Thermoelectric generators directly convert heat into electricity via the Seebeck effect. Magnetohydrodynamic generators directly convert heat into

The equation for the power extracted by a wind turbine (P) is expressed as follows: P = 0.5 * ρ * A * v 3. Where: P is the power in watts (W), ρ (rho) is the air density in kilograms per cubic meter (kg/m 3 ), A is the rotor area in square meters (m 2 ), and. v is the wind speed in meters per second (m/s).

As wind power technology points to increase power ratings, the implementation based on a permanent-magnet synchronous generator (PMSG) with a full-power converter is expanding its market share. Multilevel converters, as for example, neutral-point clamped (NPC) converters, are therefore well suited for this application.

Wind turbines convert the kinetic energy of wind into mechanical or electrical energy. Modern wind turbines are much more efficient than older designs, able to generate 250-300 kilowatts compared to older models generating around 30 kilowatts. Wind turbines work by using wind to turn blades which spin a shaft connected to a generator,
