Abstract
A method and system to prevent the equipment corrosion in an offshore wind turbine by minimizing the humid ambient air entry into the turbine. The method uses the fact that the ambient air entry into or the inside air leakage out of the turbine can be minimized by lowering the air pressure difference across the outside and inside faces of the seals. The proposed system includes a slotted, streamlined plenum over each of these interfaces that helps moderate the air pressure on the outside of the seals. On the inside, the air pressure over the seals is controlled by a variable air flow resistance system that consists of two circular, coaxial perforated plates that can rotate relative to each other.
