The development status of offshore wind farms in China

As global offshore wind power begins to enter a large-scale development stage, the 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 market conditions for development and utilization are good, however, as those in 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, Provinceof Hebei, 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 investment owners of a 100,000 kilowatt Shanghai Donghai Bridge wind farm was successfully completed in 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. develops Donghai Bridge 100MW offshore wind farm project with total investment of 2.25 billion yuans. 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 electricity production 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 can be completed in 2014. The use of wind energy can reducere carbon dioxide emissions of 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 is expected to be planned and constructed 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 period of the “Twelfth Plan", Hebei Province will prioritize the development of some wind farms in Tangshan, with a newly installed capacity of 500,000 kilowatts.

The first is the principle. If you can connect to the grid, then the phase, frequency and waveform of the electricity sent will be consistent with the grid. Then the load of the power grid is determined by the user, and the load is changed according to the distribution curve calculated by statistics, and then the task of adjusting the load is simply left to the power plant (if convenient )). Thermal power plants, nuclear power plants and hydroelectric power plants can all adjust load levels. Of course, nuclear power plants generally do not operate as peak-shaving power plants. Thermal power plants adjust the amount of coal burned, hydroelectric power plants adjustTent water flow and nuclear power plants are too difficult to adjust. Then came the wind power adjustment. You cannot decide the speed or direction of the wind. If it is windy, you will have electricity. If there is no wind, it will be lowered. generated. When the wind is weak, the electricity will be weak. This electricity. How can I offer it? The power grid is actually allowed to fluctuate, and it is impossible for all power plants to operate stably, so low impact is still acceptable for the large power grid. It therefore does not matter whether small-capacity wind energy is connected to the electricity grid. If you change it here, I will have to work hard to change the thermal power generation there (people at this plant will scold you). to death, it's really annoying). However, there are problems with large capacity wind energy access systemsity. Instability means the power supply is unreliable, which will impact the power grid. Instability is the most taboo of the power grid, so unreliable power supply is a significant problem. factor limiting the development of wind energy. So how wonderful is a big battery? If you put a large battery in a wind power station for charging, it can be connected to the grid when it is full, and then recharged when it is empty, which can solve the problem of. energy storage is good wind energy.
