In Tuoli Township, Urumqi County, about 10 kilometers from Dabancheng Wind Farm, Tuoli Wind Power Plant with a total investment of 900 million yuan and a planned installed capacity of 100,000 kilowatts officially inaugurated.
According to Chen Sui, project investor and general director of Beijing SDIC Energy Saving Company, the Toli wind power plant is expected to be gradually completed in three phases over three years. By then, its size is expected to be larger than that of the current Dabancheng wind power plant.
The first phase of the power plant has an installed capacity of 30,000 kilowatts and a total investment of 260 million yuan. It is planned to use 20 wind turbines with a single capacity of 1,500 kilowatts. be completed and put into production by the end of 2005. After commissioning, the annual power generation capacity will be 95.43 million kilowatt hours. It should allowSave 34,000 tonnes of standard coal and reduce carbon dioxide emissions by 80,000 tonnes each. year. The installed capacity of the second and third phases of the project is 30,000 kilowatts and 40,000 kilowatts respectively and will be completed in 2006 and 2007. Additionally, once the construction of the 100,000 kilowatt Toli wind farm is completed, the company will continue to expand it and will strive to reach an installed capacity of 235,000 kilowatts.
Wind power generates several kilowatt hours of electricity per cycle
As global offshore wind power begins to enter the development phase at Large-scale construction of offshore wind farms in China has also begun. In terms of offshore wind power, the developable offshore wind resources on China's east coast amount to approximately 750 million kilowatts. Not only is the resource potential enormous, but the coMarket conditions for development and use are, however, good, as those of China. The coast is often affected by typhoons, construction conditions are more complicated than abroad.
In 2004, the 20,000 kilowatt offshore wind farm project in Nan'ao, Guangdong, with a total investment of 240 million yuan, was approved. This is the first offshore wind farm construction project in China. In mid-2005, the management committee of Huanghua Port Development Zone in Cangzhou City, Hebei Province signed an agreement with Guohua Energy Investment Co., Ltd. to cooperate in the construction of China's first large-scale offshore wind power plant, with a total installed capacity of approximately 1 million kilowatts. At the end of 2007, the bidding and evaluation process for investors in the 100,000 kilowatt Shanghai Donghai Bridge wind farm was successfully completedin Shanghai. On November 28, 2007, China's first offshore wind power plant located in Liaodong Bay, Bohai Sea, was officially put into operation. This technology and experience have been accumulated for the future development of offshore wind power in China and marked a new breakthrough in the development of wind power in China. .
Shanghai Donghai Wind Power Co., Ltd. is developing the 100MW Donghai Bridge offshore wind farm project with a total investment of 2.25 billion yuan. It is expected to be put into service in 2010 and will become the first. largest offshore wind farm in Asia, meeting the needs of the daily electricity consumption of 200,000 residents of Shanghai.
It is reported that Hong Kong is about to build the world's largest offshore wind power plant in the offshore area. The power plant occupies 16 square kilometers of sea area. Annual productionelectricity is planned. The new wind power plant will have a capacity of 201 megawatts, which will be the largest power supply in the world. The largest capacity wind farm will be connected to Hong Kong's power grid via a 25-kilometre-long underwater cable, which is expected to provide enough electricity to power 80,000 homes. CLP Hong Kong will launch a month-long public consultation If all goes well, the offshore wind farm could be completed in 2014. Using wind energy can reduce carbon dioxide emissions by up to 300,000 tonnes per year . Hong Kong also plans to turn the power station into a tourist attraction to attract tourists.
In 2012, the National Energy Administration issued a response to the "Hebei Province Offshore Wind Farm Project Plan" and agreed that the Hebei Province Offshore Wind Farm should be planned and constructedt with a total installed capacity of 5.6 million. kilowatts, including 4.3 million kilowatts in the Tangshan region, which has 1.3 million kilowatts. Hebei Province is speeding up preliminary work on its first offshore wind power project, the 300,000-kilowatt Bodhi Island Offshore Wind Power Demonstration Project in Leting County, Hebei Province, and is striving to meet approval conditions this year and begin construction next year. During the "Twelfth Five-Year Plan" period, Hebei Province will prioritize the development of some wind farms in Tangshan, with a newly installed capacity of 500,000 kilowatts.
Wind power generates approximately 0.1 kilowatt hours of electricity per revolution.
Wind power generation: At rated speed, a 100 kW wind turbine generates 0.1 kWh of electricity per cycle. When wind power is enoughhealthy and stable, 2MW direct drive wind power generator can do it. can generate 2000 degrees of electricity every 60 minutes. Among them, each rotation of the fan blade takes 3.5 seconds. Wind turbines from 50 W to 300 W are 12 V, and there are 24 V wind turbines in the range of 300 W to 800 W.
A wind turbine is an electrical device that converts wind energy in mechanical work. The mechanical work causes the rotor to rotate and ultimately produces alternating current. Its operating principle is relatively simple. It uses the sun as heat. source and atmosphere as operating principle. The thermal energy from the environment is used by the generator. As an energy source replacing human and animal energy, it plays an important role in developing productivity. Wind energy production often poses no fuel problems and does not produce pollution atmospheric.
Disadvantages of wind energy
1. Instability: Instability and unpredictability of wind speed is a major challenge for wind energy. Changes in wind speed will cause fluctuations in electricity generation, which will affect the stability of the power grid. In addition, the seasonality of wind speed and geographic location also affect the efficiency and scale of wind power generation.
2. High construction and maintenance costs: Although wind power is a type of renewable energy, its construction and maintenance costs remain high. Wind power generation requires equipment such as large generators and towers, which are expensive to manufacture and install. Additionally, because wind power equipment operates in harsh environments, it requires frequent maintenance and repairs, whichwhich also increases their operating costs.
3. Geographic Location Restrictions: Wind power generation requires sufficient air flow and appropriate wind speed, so choosing its geographic location is very important. A suitable geographic location can improve the efficiency and scale of wind power generation, but it is also limited by geographic location. For example, it is difficult to establish wind power plants in mountainous areas, oceans and other areas.
