In wind-energy plants, an emergency power supply is currently provided for specific parts by accumulators, in particular, lead accumulators, so that if a power failure should occur, the wind-energy plant can be positioned to preve nt damage to said plant. However, the disadvantage of lead accumulators is that they are relatively heavy, occupy a great deal of space and cannot be charge d and discharged indefinitely. The charging and discharging properties of the lead accumulators also diminish with time and in addition, accumulators require relatively costly maintenance, which increases the cost of a wind- energy plant and its operation. The aim of the invention is to avoid the aforementioned disadvantages. To achieve this, a capacitor accumulator is us ed instead of an accumulator as the storage device for electric energy in a win d- energy plant. |
