1. Refers to the sum of the rated power of all steam turbines or hydroelectric generating units installed in a thermal power plant or hydropower station. It is one of the main indicators that characterizes the construction scale and power production capacity of a thermal power plant or hydropower station.
2. The unit is W. The installed capacity should generally be determined by the Electric Power Design Institute or other relevant technical departments according to the local objective conditions and the needs of the power industry construction and development plan at that time. It can only be determined after comprehensive consideration of different options and comprehensive analysis and comparison of politics, technology, economy and other aspects.
3. The sum of the installed capacity of all thermal power plants, hydropower stations and other types of power plants in the entire power system is called the "installed capacity" of the power system.
Annual power generation of wind power in Daan City
The investment amount, power generation and economic benefits of offshore wind power projects will be affected by many factors, such as the local water depth, wind speed, equipment selection, construction cycle, policy subsidies, etc. Therefore, it is impossible to give an accurate answer. The following only provides a rough reference:
1. Investment amount: The investment amount for 1GW of offshore wind power is usually more than billions of dollars. The specific investment amount depends on the project location, equipment selection, construction period and other factors.
2. Power generation: The power generation of offshore wind power is related to the water depth, wind speed, wind energy density and other factors of the location. Generally, a 1MW offshore wind turbine can generate about 25-35 million kilowatt hours per year. Therefore, a 1GW offshore wind power project can generate an average of about 25-35 billion kilowatt hours per year.
3. Economic benefits: The economic benefits of offshore wind power include power income, policy subsidies, carbon emission reduction and other factors. Generally speaking, the investment return cycle takes several years to more than ten years, depending on factors such as the investment amount of the project, policy support, and power market prices.
It should be noted that the above data are for reference only, and specific data need to be evaluated based on actual project conditions.
How much power can a 750KW wind turbine generate in one hour?
As of March 30, 2023, the annual wind power generation capacity in the region is 1.61 billion kilowatt hours.
According to the official website of the National Development and Reform Commission, we learned that the annual power generation capacity of the Huaneng Jilu Daan City 500 MW wind power project in Da'an City is 1.61 billion kilowatt hours.
The total installed capacity of this project is 500 MW and 119 wind turbines are installed. This kind of power generation can meet a large amount of electricity demand and also plays a positive role in environmental protection. It can replace 483,000 tons of standard coal and reduce carbon dioxide emissions by 1.256 million tons every year.
The power generation of a 750KW wind turbine is generally 300~500 degrees per hour (calculated based on wind power levels 3 to 4).
The rated power generation of the 750KW wind turbine per hour is 750 degrees, the actual power generation depends on the actual wind power and wind volume. When the wind is level 3 to level 4 (the wind speed is about 5 to 8 meters per second), the output of the wind turbine is generally 40% to 60% of the designed output. When the wind is level 5 (the wind speed is about 9.5 meters per second), it can generally reach More than 90% output.
A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. Broadly speaking, wind energy is also solar energy, so it can also be said that a wind turbine is a thermal energy utilization generator that uses the sun as the heat source and the atmosphere as the working medium.
Converting the kinetic energy of the wind into mechanical kinetic energy, and then converting the mechanical energy into electrical kinetic energy, this is wind power generation. The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then use a speed increaser to increase the speed of rotation to prompt the generator to generate electricity. According to current windmill technology, power generation can begin at a breeze speed of approximately three meters per second (the degree of breeze).
Wind power is forming a craze in the world because wind power 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 of 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; the 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.
