Title:
A WIND TURBINE GENERATOR
Document Type and Number:
WIPO Patent Application WO/2013/097862
Kind Code:
A3
Abstract:
A wind turbine generator is disclosed herein. In a described embodiment, the wind turbine generator comprises an electrical generator 101 configured to generate AC signals, a plurality of power converters 110,112,111 operated by a gating signal with each power converter configured to convert the AC signals from the electrical generator 101 into fixed frequency AC signals. The wind turbine generator further comprises a controller configured to enter a fault mode when a grid voltage falls outside an acceptable threshold, and during the fault mode the controller is configured to provide a reactive current reference dependant on a grid voltage distant from the wind turbine generator.A method of controlling a wind turbine generator is also disclosed.
