Abstract
A wind farm in which electrical power produced in the wind farm is transported via a wind-farm-internal network to a substation. Upon being transferred to an external network, the electrical power is transformed to a voltage which is higher by a selectable step-up ratio than the voltage in the wind-farm-internal network. The electrical load level on a wind energy installation in the wind farm is determined, and the step-up ratio is adjusted as a function of the electrical load level. Accordingly, it is possible to influence the voltage in the wind-farm-internal network such that the wind energy installations are subject to a lower electrical load level.
