Coordinated control of DFIG's rotor and grid side converters during network unbalance
Voltage unbalance can cause wind farms to trip resulting in the loss of power generation. This research paper proposes a coordinated control strategy for operating doubly-fed induction generator (DFIG) based wind turbines during network unbalance. This enables the wind turbines to continue to operate during large voltage unbalance, and thus increases power production and reduces the likelihood of system disconnection. The new strategy developed during this EPSRC supported research [EP/D029775/2, £62k, 2007-2008] was adopted by Gamesa [Daniel Navarro, dnavarro@gamesacorp.com], one of the world’s major wind turbine manufacturers.
