The automatic brake system can detect the parameter such as the wind speed, DC Output Voltage of the system and the switch signal to control the status of brake on and brake off.
The blade angle of normal wind turbines was fixed, thus rotating speed of the wind rotor will be increased rapidly. In this case, it will cause the blades break away from wind turbine body.
As the traditional wind turbine has the problems of high wind speed start-up, sluggish control, and meanwhile it exists security risk and reduces the use efficiency of wind power...
Under the right conditions, for example when the utility pays a sufficient price for wind-generated electricity, you may be able to farm the wind for profit.
There are two types of wind turbines suitable for producing utility-compatible power: those that use induction (or asynchronous) generators, and those that use inverters. Regardless of which is used, their interconnection with the utility is the same.
If installation place is limited and many wind turbines are arranged, find the prevailing wind
direction and take full advantage of local conditions according to local terrain.
If wind turbine is installed in the upwind direction of building, it needs to be at least 2 times of building height away from buildings; if wind turbine is installed in down ...
Mountains can be natural high tower for wind turbine, and air flow near ridges can get accelerated and has more power, but wind direction and ridge direction can influence ...
