<p>The purpose of the invention is to reduce the disadvantageous torque vibrations occurring on the electric network of a ship. The vibrations of the local network can be reduced by controlling the load of the network so that the vibrations are dampened. The load to be controlled can be, for example, an electric motor (7) receiving its electric power via a frequency converter (5). When the frequency converter is suitably controlled, the frequency converter and the electric motor consume vibrations, i.e. the vibrations of the local network are dampened.</p> |
