Abstract

A controller 101 for one or more generators, for example doubly fed induction generators (DFIG) attached to a wind-turbine 100, where each generator has voltage source converters 110, 112 connected on its rotor side for controlling the power at its output side. An imbalance detector 116 detects any imbalance in the grid served by the generators and the voltage source converters are controlled accordingly. Processing means 118 are provided for calculating the current orders for both positive and negative sequences according to a required active power output and these are communicated to the controllers of the voltage source converters. A plurality of DFIGs (e.g. a wind farm) may be provided (100a-g, Figure 2) having a system controller (200, figure 2).
