Design of Wind Power All-DC System Based on the Turbine-Side New Step-Up Conversion

Wind power all-DC system architecture is an important research approach for wind power system design. For effectively solving the problem of low energy output efficiency of all-DC wind farms due to turbine-side multi-stage energy transformation, a DC wind power system design architecture with turbine-side new step-up conversion as the carrier is proposed in this paper. Based on the adopted turbine-side new step-up conversion mode, the operation and control of the proposed system structure are analyzed in this paper. This paper sets up the simulation architecture of the system. On the basis of realizing the feasibility of system operation, it verifies that the proposed wind power all-DC system structure based on turbine-side new step-up conversion can effectively improve the energy transmission efficiency of the wind farm by comparatively calculating the steady-state operating loss of the wind farm.
