Abstract
Provided is a method for removing moisture from a cooling air filter installed for filtering first cooling air for cooling a generator from a first end, the method including: pressurizing second cooling air cooling the generator from a second end; allowing the second cooling air having received heat from the generator to pass through the cooling air filter, in order to absorb and thereby reduce moisture from the cooling air filter.

A method for removing moisture from a cooling air filter installed for filtering first cooling air for cooling a generator from a first end, the method comprising:
- pressurizing second cooling air cooling the generator from a second end;
- allowing the second cooling air having received heat from the generator to pass through the cooling air filter, in order to absorb and thereby reduce moisture from the cooling air filter.
A cooling system for cooling a generator of a wind turbine, the system comprising:
- inlet fans;
- heated cooling air withdrawal fans;
- a cooling air filter;
- and
- a controller configured to supply control signals to the inlet fans and to the heated cooling air withdrawal fans,
- to control the inlet fans to convey ambient air into a space region as second cooling air and pressurize the second cooling air;
- and
- to control the heated cooling air withdrawal fans to withdraw cooling air being heated by heat reception from the generator and further to allow the second cooling air having received heat from the generator to pass through the cooling air filter, in order to absorb and thereby reduce moisture from the cooling air filter.
