For grid connected systems, there must be a reliable power grid/transmission network near the site so that the wind generated power can be fed into the grid. Normally, the wind turbine generates power at 400 V, which is stepped up to 11-110 kV, depending upon the power capacity of the wind system. If the wind power capacity is up to 6 MW, the voltage level is stepped up to 11/22 kV; for capacity of 6-10 MW, the voltage level is increased up to 33 kV; and for capacity higher than 10 MW, it is preferred to locate a 66 or 110 kV substation at the wind farm site [9].
