The deployment of wind farms in bodies of water is known as offshore wind power or offshore wind energy. Because offshore wind speeds are higher than on land, offshore farms generate more electricity per unit of capacity building.
What is Meant by Offshore Wind Energy?
Unlike how the term “offshore” is commonly used in the marine sector, offshore wind power encompasses both inshore and deeper-water locations, such as lakes, fjords, and sheltered coastal areas. In relatively shallow water, most offshore wind farms use fixed-foundation wind turbines.
How does Offshore Wind Power Work?
The blades are first turned by the wind’s power. Through the hub, the blades are connected to the nacelle. The blades rotate at the same speed as the low-speed shaft (7 – 12 turns per minute). The gearbox multiplies this speed by a factor of 100 before transferring it to the high-speed shaft. The generator receives this speed via the high-speed shaft (+1,500 revolutions per minute). The generator converts the received kinetic energy into electricity.
The generator produces electricity, which is fed down the inside of the tower. Direct current is converted to alternating current via the converter. To transmit the voltage across the wind farm, the transformer raises the voltage (33 kV – 66 kV). The electricity is delivered to the substation via underwater cables. The electricity is transformed to a high voltage current (+150 kV) at the substation. Electricity is delivered to households via the distribution network.
What are the 3 Advantages of Wind Power?
Wind power has numerous and compelling benefits. Let’s have a look at the three key benefits of wind energy:
1- There is no pollution.
There are two primary drawbacks of relying on fossil fuels for energy.
One is that they are a scarce resource that will, in as soon as 70 years, be unavailable to us.
The second is more regrettable: the massive amount of pollution produced by their use. Particulates, carbon dioxide, nitrogen oxides, and sulfur dioxide cause a slew of health, environmental, and economic issues, as well as being the primary contributors to greenhouse gas emissions, smog, and acid rain. Wind energy does not emit any pollutants.
It is the primary source of renewable energy we purchase for our consumers because it is clean and renewable.
Land-based wind turbines produce some of the cheapest electricity on the planet thanks to a free energy source. Only 1-2 cents per kilowatt-hour, according to the Office of Energy Efficiency and Renewable Energy (kWh).
