Abstract

It is known in wind power installations to provide for certain parts thereof an emergency power supply by means of accumulators, in particular lead accumulators, so that in the event of a power failure the wind power installation can be put into such a position that no damage to the wind power installation occurs.
The disadvantage of lead accumulators however is that they are relatively heavy, they take up a great deal of space, and lead accumulators cannot be charged and discharged an unlimited number of times. In addition the charging and discharging properties of the lead accumulators deteriorate with time and furthermore accumulator storage means require relatively expensive maintenance so that they increase the costs of a wind power installation and operation thereof.
The object of the invention is to avoid the above-mentioned disadvantages.
Use of a capacitor storage means as a storage means for electrical energy instead of an accumulator in a wind power installation.
