6 FAQs about [Wind turbine transmission line routing]

How do I get access to a wind farm transmission system?

The process of gaining access to the transmission system is also complicated and costly. Much like securing a project site, when developing a new wind farm it is imperative to conduct similar due diligence on the local transmission system. Research the local infrastructure and look into proposed upgrades to transmission systems and substations.

What is the electrical network of an offshore wind farm?

An electrical network of an offshore wind farm can be seen in Fig. 3. It consists of: wind turbines with their own internal transformer; internal submarine cable; offshore substations (if needed); transmission submarine cables and onshore substation with onshore cables . This whole system is connected to a Point of Common Coupling (PCC).

Can transmission lines be located near a new wind-farm site?

Transmission lines may be located near a potential new wind-farm site, but gaining access to the lines is another matter that can prove challenging and costly. There have been plenty of new developers who’ve secured a project site and permits only to find out nearby transmission lines cannot carry more load.

What does a wind power request mean?

This request is for the right to use a specific amount of capacity on the grid to deliver wind-generated power from one location to another. It is a good sign and means your wind project is ready to go from a transmission viewpoint, but it won’t come cheap.

How many HVAC lines are needed for a wind farm?

Therefore several HVAC lines are needed (33 kV) for the transport of electrical power to the grid. Between 10 and 60 km, a preferred solution is now to use one transformer (or many) in an offshore substation. Offshore wind farms will be connected to the onshore electrical grid by one or several HVAC lines (130 kV - 150 kV).

How will offshore wind farms be connected to the onshore electrical grid?

Offshore wind farms will be connected to the onshore electrical grid by one or several HVAC lines (130 kV - 150 kV). Currently 245 kV HVAC lines are available and 400 kV HVAC lines will also be available in the near future . One of the problems is the limitation of the allowed transmitted power by these lines.
