For the achievement of voltage stability wind power into the power grid

a kind of new reactive voltage compensation and control method is discussed in this paper. As for the basic function of cluster interconnection possessed by the large wind farm in the field of reactive voltage control

stability control of grid safety

the hierarchical portioning control strategy of the cluster interconnection of the large of the wind farm in the aspects of multiple time and space scale is proposed based on the existing reactive voltage control technology of wind power grid and with addition of new theory of progressive reactive voltage optimization and control. In this paper

the simulation and verification analysis with certain wind farm in Xinjiang as an example is performed. It is shown by the result that the reactive power coordination and control result of this wind farm is remarkably superior to the control strategy of single wand farm or cluster station and the control scheme has an important guidance to the study of reactive power compensation in the future.
