Method and system for controlling a wind installation to network faults.
2008
Method and system controlling a wind installation to network faults. The present invention relates to a method and system for controlling a wind power installation connected to an electrical network, when a fault occurs in the network. In electrical machines that are part of the wind farm, generators and transformers, you can change the impedance terminating the neutral introducing a plurality of active and passive components. Thus the circulating currents are limited during the power failure so that the peak torque is reduced in the mechanical train of wind turbines and allows in turn ensure compliance with the requirements of network connection as it remains in all times control of active and reactive currents.
