Method for operating a windmill generating station system and windmill generating station system per se

摘要

The invented method for operating a windmill generating station system with an electric generator driven by a rotor for the production of electrical power for an electrical user, in particular an electrical network is characterized in that in case of a short circuit within the electrical network or a similar operating failure during which voltage deviates by more than 20 percent from a reference value, an actuating and regulating device (10) switches on (10). The aim of this device is to regulate electric power supply to the network (6) without exceeding predetermined threshold values of current supplied to the network by the electric generator (12). The invention also relates to such windmill generating station system provided with an electric generator that is permanently connected to an electrical network (6) even when a short circuit or the like operating failure occurs and voltage deviates by more than 20 percent from a reference value. Such system comprises an actuating and regulating device (10) situated if front of external input (22) in the network (6) and intended for regulating delivery of electric power to the network (6) and to supplementing the network (6). Current supplied by the electric generator (12) achieves in case of a short circuit or another operation failure a predetermined threshold value.
