A system for protection and control against symmetric and asymmetrical faults for asynchronous generators.

摘要

The invention relates to a system for controlling and protecting against symmetrical and asymmetrical faults for double-fed asynchronous-type generators, which, in the event of a symmetrical or asymmetrical fault, remains connected to the grid, absorbing the initial transient, and maintains control of the aerogenerator. In this way, the invention fulfils the requirements of the various different grid connection standards relating to the supply of active and reactive power in fault situations, which are intended to assist in the recovery of the grid.
