A VARIABLE WIND TURBINE HAVING A POWER DISSIPATING UNIT; A METHOD OF OPERATING A POWER DISSIPATING UNIT IN A WIND TURBINE

WIPO Patent Application WO/2012/146250

A3

A variable speed wind turbine is provided. The variable speed wind turbine comprises a generator, a power converter for converting at least a portion of electrical power generated by the generator, the power converter comprising a generator-side converter, a grid-side converter and a DC (direct current) link therebetween, a power dissipating unit operatively coupled to the DC-link, and a controller. The controller is adapted to receive a request to reduce power output from the wind turbine, determine a feed forward power signal based on a reference generator power and a desired turbine power, and operate the power dissipating unit based on the feed forward power signal.

JP6312166	To control a wind turbine, a method of controlling the wind turbine, a power generation and transmission system equipped with the wind turbine, a computer program for controlling the operation of the wind turbine, and an operation of a grid-side bridge of a power converter in the wind turbine.
