Abstract. The paper presents <strong>the</strong> methodology and <strong>the</strong> results<br />
from <strong>the</strong> analysis by numerical simulation <strong>of</strong> a self adaptive<br />
hydraulic transmission in closed circuit for low power wind<br />
turbines. In order to analyze <strong>the</strong> simulation model, realized using<br />
Simulink, <strong>the</strong> pump drive speed was considered as input value.
