In this research, a study of solution to the problems of transmission in
wind turbines, where the electronic appliances and gearboxes
components responsible for much of the wind turbine problems as they
increase the cost of operation and maintenan
ce of wind turbines and
here comes the role of variable transport systems ratios, which is a
solution more efficient than in fixed proportions regimes where create
a dynamic model of the turbine wind using the aerodynamic properties
of the blade wind and calculate torque when the wind changing speeds
values and this for each of the wind turbine with proportions variable
order and fixed ratio using MATLAB software and after study shows
that energy production is slightly higher and more importantly, so it is
possible to say that the CVT system is a candidate to be the subject of
research for future developments of the technology of wind turbines.
The objective of this research is to model the dynamic
characteristics of lead-acid batteries taking into account their
fundamental phenomena (the electric double-layer, the charge
transfer and diffusion phenomenon due to oxidation and reduction
reactions). The value of the equivalent circuit elements used in
modeling is determined experimentally using a pulsed discharge of
the battery.
