Anonymous users2024-02-10OK. It is often assumed that the power of wind power is determined entirely by the power of the wind turbine, and that there is always a desire to buy a larger wind turbine, but this is not true. At present, wind turbines only charge batteries, and the batteries store the electric energy, and the amount of electricity that people ultimately use is more closely related to the size of the battery.
The amount of power depends more on the amount of airflow, not only the power of the head. In the mainland, small wind turbines are more suitable than large ones. Because it is easier to be driven by a small amount of air to generate electricity, a continuous light wind will provide more energy than a temporary strong wind.
When there is no wind, people can also use the electric energy brought by the wind normally, that is to say, a 200W wind turbine can also be used with a large battery and an inverter to obtain 500W or even 1000W or even greater power.
A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and finally outputs alternating current. Broadly speaking, wind energy is also solar energy, so it can also be said that wind turbines are a kind of thermal energy utilization generators that use the sun as the heat source and the atmosphere as the working medium.

Anonymous users2024-02-09At present, most wind turbines are AC asynchronous generators, and the electrical energy generated by them needs to pass through a rectifier to charge the battery. As long as the voltage generated by the wind turbine is greater than the battery voltage and the cut-off voltage of the rectifier diode (or thyristor of the controllable rectifier), the battery can be charged.
However, there is one thing that I don't understand, that is: the charging current depends on how much the generator voltage is larger, how can it be said that the charging current is very small? If the generator voltage is really too small, it is estimated that the generator rotor has no remanence, and measures should be taken to magnetize!
After the magnet is charged, the voltage increases. After the voltage is generated, the specific charging voltage can usually be controlled by the controllable rectifier, and the current cannot be very small after connecting the battery!

Anonymous users2024-02-06Summary. Hello! Can the electricity generated by the wind turbine be charged directly to the battery?
Hello, happy to serve you, no. When charging the battery, the battery can only be charged if the voltage is greater than or equal to the charging voltage of the battery. When the voltage is lower than the rated input voltage, the battery cannot be charged.
Hello! Can the electricity generated by the wind turbine be charged directly to the battery?
Hello! Can the electricity generated by the wind turbine be charged directly to the battery? Hello, happy to serve you, no.
When charging the battery, the electric defeat alarm voltage can only be charged when it is greater than or equal to the charging voltage of the battery. When the hood voltage is lower than the rated input voltage, the battery cannot be charged.
What kind of voltage can rush in.
The charging voltage must be higher than the rated voltage of the battery before it can be charged.
Can the mobile phone rush into it?
No. How much wind does the wind have to play to produce 3,7 electricity?
The electricity generated by the wind turbine can only be used, not stored.
How no one. The small household wind-powered generator can be connected to the Youshen battery pack to store electric energy; The generation of large (MW level) wind turbine generators needs to be connected to the grid and cannot be stored.

Anonymous users2024-02-05This failure is generally caused by the desoldering and disconnection of individual silicon diode leads or the poor contact between the brush and the slip ring, and the specific reasons are as follows:
1. The belt is slippery.
2. The voltage of the regulator is low.
3. The magnetic field line of the diesel generator is tied to the iron or the magnetic field coil is partially connected to the iron and short circuit, etc.
4. The silicon diode lead wire of the diesel generator is unsoldered and disconnected, so that the armature coil is disconnected from one or two phases.
5. The contact between the brush and the slip ring is poor (there is dirt on the slip ring, the carbon brush is too worn, the spring pressure is insufficient, etc.), and the contact resistance is large, which makes the excitation current smaller.
The following solutions should be taken to address this phenomenon:
1. Check the contact between the brush and the slip ring of the diesel generator, and no abnormality was found.
2. Measure the output voltage of the regulator with the DC voltage block of the multimeter, and find that the output voltage is very low.
3. Measure the output voltage of the generator with the DC voltage block of the multimeter, and find that the output voltage is 5V (disconnect the wiring between the regulator and the battery during measurement), which proves that the fault is on the charging generator.
4. When measuring the diode, it was found that 4 diodes burned out. When the diode is replaced, the diesel generator is assembled, and then the diesel generator is started to 1300r min, the charging ammeter on the dashboard shows 15A, indicating that the diesel generator is charging normally.

1) If the load is too large, the load should be lightened.
2) In the event of a phase-to-phase short circuit or grounding fault in the transmission line, the line should be overhauled, and it can be restored to normal after troubleshooting.
1) In the low wind speed area, the role of the pitch is mainly to reduce the blade angle in the case of a sudden decrease in wind speed, so that the wind turbine can recover the stable power generation capacity faster. 2) In the area of high wind speed, the oars should be quickly retracted at the moment of fall to prevent the impact on the fan, the overspeed of the impeller and the overcurrent impact on the converter. However, due to the speed limitation of the pitch, the angle of the pitch is also limited at the time of voltage drop, which can generally be changed by about 5-10 °, and its effect is not small. >>>More
The basic principle of the design of wind turbines is that when the power that can be captured by the kinetic energy of the air is less than its rated power, the wind energy can be captured as efficiently as possible, but not beyond some constraints, such as its rated speed. When the kinetic energy of the air that can be captured is greater than its rated power, the capture of wind energy is actively reduced and maintained at the rated power. Friends who know more about it may know that the power curve is such a thing, as the wind speed gradually increases from cut-in speed (cut-in speed), the power curve of steady state can be basically divided into three dash lines: >>>More
Although the leaves of wind power generation rotate slowly, the energy generated by one rotation is very large, so it can generate electricity, and if the leaves of wind power generation turn fast, they will be damaged.

2. Dismantle three more heart-piercing wires; >>>More
Generally, the height of the wind turbine should be 6 meters higher than the surrounding obstacles, so as to achieve the best power generation effect. >>>More
