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.
La presente invención se refiere a un método y sistema para el control de una instalación eólica conectada a una red eléctrica, cuando se produce una falta en dicha red. En las máquinas eléctricas que forman parte de la instalación eólica, generadores y transformadores, es posible modificar la impedancia de cierre del neutro introduciendo una pluralidad de elementos activos y pasivos. De esta forma se limitan las intensidades circulantes durante el fallo de red con lo que se reduce el pico de par en el tren mecánico de los aerogeneradores y permite a su vez garantizar el cumplimiento de los requisitos de conexión a red, ya que se mantiene en todo momento el control de las corrientes activas y reactivas.
