1. The wind angle of the wind turbine is adjustable. When the wind force changes within a certain level, the blade torque can be kept unchanged and the speed is stable;
2. the speed increases At this time, the power output of the generator will also increase, and the energy consumed in power generation will compensate for the increase in wind energy, making the speed of the motor stable;
3. by wind energy production is converted and used by special equipment. The generator itself allows considerable fluctuations in electricity production (voltage, current);
4. Wind power plants are built in places where wind energy is relatively stable;< /p>
5. Pass With the above method, the wind turbine can generate stable power most of the time under special circumstances (like super typhoon), special methods such as blade lockand disconnecting the motor. can be used to avoid accidents
Can the leaf shape of a wind turbine be transformed into an electric fan?
1. Because wind energy harms the environment much more than wind energy. Due to the economic benefits it generates and being even less environmentally friendly, it was discontinued. The damage includes:
2. Wind power generation will harm the local ecological environment, destroy vegetation, change topography, cause water erosion and soil and will make the land desertified.
3. Electromagnetic radiation produced by wind power generation affects human habitation. In wind power generation systems, generators, substations, transmission lines, etc. are the main causes of electromagnetic radiation. . When the receiving device fixed to the wind power plant receives the signal, it will receive the electromagnetic wave signal reflected from the wind turbine blades. Reflected signals are delayed signals that can have a significant impact on AM radio systems.
4. Wind energy affects the local climate. Wind energy uses wind energy present in the atmosphere. According to the law of conservation of energy, the consumption and production of one type of heat must produce or consume another type of energy. Therefore, the energy production process of wind turbines must consume some of it. Wind energy in the atmosphere, and wind energy is climate change. One of the important factors of change, its changes will inevitably lead to climate change.
5. Wind power blades are prone to safety accidents when wind turbine blades are subjected to strong winds of more than25 m/s, although the wind turbine is stopped. In the state, the root of the blade will be limited. In severe cases, the entire blade can fly away, causing casualties and damage to buildings on the road.
6. Noise hazards caused by wind power generation For a wind turbine of such size, when the long blades rotate, noise is inevitable. Wind blade noise can be roughly divided into three categories: Thickness noise, which is produced by the compression of the air and the blades. In windy weather, when doors and windows are closed, you often hear a sharp, harsh sound, which occurs. Does it look like a crying ghost or a howling wolf? , coupled with the dark sky outside, it's a bit scary to think about it; load noise, as the name suggests, is caused by the blades carrying a large load; that is, when Mach occurs when the number is close to 1. In this way, the imnoise pact on the environment cannot be ignored.
Are the fan blades of large-scale wind power plants located in mountains fixed in one direction or do they rotate automatically with the wind?
I personally think that if the blades Wind turbines are made like the blades of an electric fan, firstly, the weight is too high, and the second reason is that when the wind is strong, the connecting rod will be overturned. Fan blades are made like wind turbines, which must spin at high speeds to be efficient. This will inevitably consume energy and require higher structural strength of the blades.
In order to allow the turbine to naturally align with the direction of the wind, wind turbines generally use steering devices. For large wind turbines, motor-driven wind direction tracking systems are typically used. The ensThe entire yaw system consists of a motor and a reduction mechanism, a yaw adjustment system and a twisted cable protection device. The yaw adjustment system includes a wind vane and yaw system adjustment software. The weather vane has a pulse output signal corresponding to each wind direction. Its yaw direction and yaw angle are determined through the yaw system software, then the yaw signal is amplified and transmitted to the motor, and the wind turbine platform rotates. the deceleration mechanism until it is aligned with the wind direction.
