Background of the problem
The wind energy is used to reduce the climate that change pollution and sustain the economic growth. This renewable energy standard encourage officials to develop strong methods to decline the carbon emissions.
One particularly important method that can be sluggish in reacting with high-speed wind is reduce the area that expose in the wind. It need the blade incline to one side just like a helicopter or by the means of combining two blades.
Design and build a renewable energy system that can reach and sustain the highest possible voltage.
The principle of wind power generation is the use of wind power to promote the rotation of the wind turbine blade, then, the speed would increase through the wind-power speed increaser.
In the mainland, small wind turbines will be more appropriated. Because it is more likely to be moved by small wind, in that condition, the generator would even produce greater energy than strong wind.
By means of choosing the box that can change the speed and the angle between two blades carefully, it is suitable to use the stall point to avoid the overload. However, this is just really matter to some extent. It need a wonderful brake to stop the turbine if the situation is in a stronger wind. This is an attractive option for some turbine designers that want to use the electrical load, instead of the means that use machine to protect it from overloading.
When the wind becomes stronger, the turbine will produce more current and hence higher torque. However, the rpm does not increase enough to maintain an angle of attack that it can use, so “stall-regulated” limits their output and protect themselves to avoid the strong wind without any mechanisms.
Wind turbine blades pass through the wind and slow the wind down. This kind of interaction is produced by the lift force on the blades that drives to rotate. The airflow over a blade of the windmill turbine is divided into two parts—the natural wind and the wind produced by the rotation of the blades. When the shaft acts as electric braking, the rpm depends on the balance between what the wind can do to the turbine and how much power it needs. But if the shaft spins without resistance, the wind will over speed. In that case, the turbine will overload and its lift-drag will drop dramatically.
For the electrical braking, it depends on the speed of the the balance between the use of wind and the power that it is required when the turbine is working. If the turbine rolls without the resistance, the blades will over speed.
The wind turbine consists of a nose, a swivel, a tail, and a blade.
The machine should be converted into a communication 220V to ensure stability.
