Patent number: 8541898Abstract: The present invention relates to a method and system for controlling a wind power installation connected to an electrical power grid, in case of a fault in said grid. In the electrical machines that form part of the wind power installation, generators and transformers, it is possible to change the impedance of the neutral closure introducing a plurality of active and passive elements. This limits the currents during the grid fault, thereby reducing the peak torque in the mechanical train of the wind turbines and allows guaranteeing compliance with the network connection requirements, as control of the active and reactive currents is maintained at all times.Type: GrantFiled: May 22, 2009Date of Patent: September 24, 2013Assignee: Ingeteam Power Technology, S.A.Inventors: Jorge Acedo Sánchez, Ainhoa Cárcar Mayor, Josu Elorriaga Llanos, Jesús Mayor Lusarreta, Susana Simón Segura, David Solé López, Mikel Zabaleta Maeztu, Jesús López Taberna, Luis Marroyo Palomo
