| titleOfInvention | Wind energy system having a connection protection device |
| abstract | The invention relates to a wind energy system having a rotor (12), a generator (2) driven thereby, said generator having a converter (3) for generating electrical power for supply to a grid (9) via a transformer (8) for which voltage monitoring is provided, and a control system (4) comprising a converter controller (34), wherein the control system (4) applies a control signal for a blind component to the converter (34). The invention provides that a voltage measuring device (51) is disposed on the transformer (8), the voltage signal of said voltage measuring device being applied to an input of a voltage-dependant target value valve (5), the output signal of said valve being applied to a limiting module (59) for the blind component acting on the converter (3). The blind component can therefore be adjusted into both directions (inductive/capacitive) as a function of whether or not an overvoltage or undervoltage is present. The invention thus achieves the combined protection, e.g. the protection of the power supply, of the transformer, and also of the wind energy system at a low additional expenditure. The invention further enables better utilization of the transformer (8). An over-dimensioning, as has been carried out thus far due to the exceeding of the tolerance threshold for the voltage, is therefore no longer necessary. In this manner smaller and more efficient transformers (8) may be utilized. At the same time, the protection of the power supply (9) and that of the wind energy system (1) are also improved. |
