An image on architecture of non-grid-connected wind system based on DC transmission

In this paper, the structure that could be applied for the power transmission in non-grid-connected wind power system is proposed. The power transmission system consists of several voltage source converters (VSC) in parallel. The wind power is connected to the high voltage DC lines in Distributed manner, and converted to low voltage by the dc/dc converters in the reception end of the grid. Finally, the wind power is used by those high-energy-cost enterprises, such as the of electrolytic aluminum production factory. In this paper, the structure of grid-connected in wind plants are analyzed and compared. Then the structure that could be applied to the power transmission in non-grid-connected wind power system is brought out.
