The 102MW second phase of Shanghai Donghai Bridge was hoisted and connected to the grid in June 2015. According to relevant information, it was learned that after the second phase of the wind power project was connected to the grid offshore Shanghai Donghai Bridge in June 2015, it was listed as a major project in Shanghai this year. The offshore wind energy project will also begin to be connected to the grid before the end of the year.
How many wind turbines are there in Yangshan Deepwater Port?
(1) The wind speed of the turbine is: v=
The resistance is : f=
(2) The power of the wind is P=
The wind energy used by each wind turbine each year is E wind=Pt=6×1 0 6 ×2000×3600J=4.32× 1 0 13 J; (3) The power generated by each wind turbine is P 0 = 3,000kW Coal consumption for electricity production = 1.8 × 10 6 / (3,000 × 2,000? )kg/kwh=0.3kg/kwh Answer : (1) The resistance of the wind turbine when towed is approximately 1.44×10 4 (2) The natural resistance of the wind energy used by each wind turbine each year is 4.32×10 13 J; (3) The consumption of coal for the production of electricity (mass of coal/kWh) is 0.3 kg/kwh |
From Yangshan Deepwater Port to Donghai Bridge, there are at least 20 units. Reason: Total capacity of 100,000 kilowatt units installed. the first phase will reach 204,200 kilowatts, so there will be at least 20 units

?The 32.5-kilometer East China Sea Bridge connects Shanghai Pudong and the deep-water port of Yangshan. Overlooking the bridge from the air, the sea bridge is the same color as the waterand the sky. The bridge extends to the end of the horizon. forest" spread over the sea on both sides of the bridge is the Donghai Bridge offshore wind power project. It is the first offshore wind power project in China and the first outside Europe. Wind farm, Donghai Bridge offshore wind farm with a total investment of 4.08 billion was completely independently developed, manufactured and completed by the Chinese, from exploration and design to main engine manufacturing and installation equipment
?2010 Donghai Bridge Offshore Wind Farm After the 100,000 kilowatt wind unit the first phase was connected to the grid to generate electricity, the builders continued to challenge the second phase. of the project on September 1, 2015, as the second phase of the project.The total installed capacity of Shanghai Donghai Bridge Wind Power Project reached 204,200 kilowatts D.ince the commissioning of the first phase of the entire offshore wind power project, a total of nearly 1.2 billion kWh has been produced compared to thermal power generation. it consumed 540,000 kilowatts less than standard tons of coal.
