The power output of a 750 kW wind turbine is typically 300 to 500 degrees per hour (calculated based on wind energy levels 3 to 4).
The rated power output of the 750 kW wind turbine is 750 degrees per hour, and the actual power output depends on the actual wind power and wind volume. When the wind is from level 3 to level 4 (the wind speed is about 5-8 meters per second), the power of the wind turbine is generally 40-60% of the designed power. When the wind is level 5 (the wind). speed is about 9.5 meters per second), it can generally achieve more than 90% output.
A wind turbine is an electrical device that converts wind energy into mechanical work, which causes the rotor to rotate and ultimately produces alternating current. Generally speaking, wind energy is also solar energy, so we can also say that a wind turbine is a generatorur using thermal energy which uses the sun as a heat source and the atmosphere as the working fluid.
Converting the kinetic energy of wind into mechanical kinetic energy, and then converting the mechanical energy into electrical kinetic energy, is wind power generation. The principle of wind power generation is to use wind energy to rotate the blades of the wind turbine, then use a speed multiplier to increase the rotation speed to induce the generator to produce electricity. According to current wind turbine technology, electricity production can begin at a breeze speed of around three meters per second (the degree of breeze).
Wind energy is gaining popularity around the world because it does not require the use of fuel and does not produce radiation or air pollution.
According to measurements, a 55 kilowatt wind turbine has an output power ofe 55 kilowatts when the wind speed is 9.5 meters per second; when the wind speed is 8 meters per second, the power is 38 kilowatts; wind speed When the wind speed is 6 meters per second, it is only 16 kilowatts; when the wind speed is 5 meters per second, it is only 9.5 kilowatts. It can be seen that the stronger the wind force, the greater the economic benefits.
Common circular tower wind turbines are typically between 120 and 140 meters tall, but are prone to resonance. The current tallest is the 160m pre-stressed steel tube wind turbine tower, which improves the safety and service life of the tower. The four corners of the frame-type wind turbine tower have stronger bearing capacity through the lower tower body, which can effectively avoid resonance. In the future, it may continue to rise to 180m, or even 200 m, which will better obtain wind resources and improve the efficiency of electricity production. Additional information: A wind turbine is an electrical device that converts wind energy into mechanical work, drives the rotation of the rotor, and ultimately produces alternating current. Wind turbines generally consist of a wind turbine, a generator (including devices), a direction regulator (tail), a tower, a speed-limiting safety mechanism and a device energy storage. The operating principle of wind turbines is relatively simple. The wind wheel rotates under the influence of the wind, and the wind converts the kinetic energy of the wind into the mechanical energy of the wind wheel shaft. The generator rotates under the drive of the wind wheel shaft to produce electricity. Generally speaking, wind energy is also solar energy, so we can alsoalto say that a wind turbine is a generator using thermal energy which uses the sun as a heat source and the atmosphere as the working fluid.
